7.5、编写roles中的文件
首先切换到上层目录
然后进入到roles文件夹下，查看当前文件夹的文件情况，修改nginx文件夹的名称为wordpress。
7.5.1、修改files文件夹下的health_check.sh文件
#!/bin/sh
URL=$1
PORT=$2

7.5.2、删除files文件夹下的index.html文件，创建index.php文件
# 删除index.html文件
rm index.html
# 创建index.php文件
vim index.php
<?php phpinfo();?>
7.5.3、创建files文件夹下的www.conf文件
; Start a new pool named 'www'.
[www]
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = deploy
; RPM: Keep a group allowed to write in log dir.
group = deploy
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen = /var/run/php-fpm/php-fpm.sock
; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0660
listen.owner = deploy
listen.group = deploy
;listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =
; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
listen.allowed_clients = 127.0.0.1
; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
; - The pool processes will inherit the master process priority
; unless it specified otherwise
; Default Value: no set
; process.priority = -19
; Choose how the process manager will control the number of child processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on the
; following directives. With this process management, there will be
; always at least 1 children.
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 50
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 5
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 35
; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;
; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500
; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been reached,
; when pm tries to start more children (works only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460
; listen queue: 0
; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full
; The Full status returns for each process:
; pid - the PID of the process;
; state - the state of the process (Idle, Running, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:
; ************************
; pid: 31330
; state: Running
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 63087
; requests: 12808
; request duration: 1250261
; request method: GET
; request URI: /test_mem.php?N=10000
; content length: 0
; user: -
; script: /home/fat/web/docs/php/test_mem.php
; last request cpu: 0.00
; last request memory: 0
;
; Note: There is a real-time FPM status monitoring sample web page available
; It's available in: @EXPANDED_DATADIR@/fpm/status.html
;
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status
; The ping URI to call the monitoring page of FPM. If this value is not set, no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension or it
; may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping
; This directive may be used to customize the response of a ping request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong
; The access log file
; Default: not set
;access.log = log/$pool.access.log

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: chrooting is a great security feature and should be used whenever
; possible. However, all PHP paths will be relative to the chroot
; (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =
; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www
; Redirect worker stdout and stderr into main error log. If not set, stdout and

; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes
; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this

; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no
; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7
; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from

; same as the PHP SAPI:
; php_value/php_flag - you can set classic ini defines which can
; be overwritten from PHP call 'ini_set'.
; php_admin_value/php_admin_flag - these directives won't be overwritten by
; PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.
; Default Value: nothing is defined by default except the values in php.ini and
; specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f [email protected]
;php_flag[display_errors] = off
php_admin_value[error_log] = /var/log/php-fpm/www-error.log

php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session
php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache
7.6、编写templates中的文件
切换到templates文件夹中
删除nginx.conf.j2文件中的内容
> nginx.conf.j2
nginx.conf.j2需要配置内容
# For more information on configuration, see:
user {{ user }};
worker_processes {{ worker_processes }};
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
worker_connections {{ max_open_file }};
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
# Load config files from the /etc/nginx/conf.d directory
# The default server is in conf.d/default.conf
#include /etc/nginx/conf.d/*.conf;
server {
listen {{ port }} default_server;
server_name {{ server_name }};
root {{ root }};
#charset koi8-r;
location / {
index index.html index.htm index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}
7.7、编写tasks中的文件
切换到tasks文件夹下，main.yml文件就是ansible-playbooks的配置文件
# 删除main.yml文件的内容
> main.yml
main.yml文件的内容如下所示
- name: Disable system firewall
service: name=firewalld state=stopped
- name: Disable SELINX
selinux: state=disabled
- name: Setup epel yum source for nginx and mariadb(mysql)
yum: pkg=epel-release state=latest
- name: Setup webtatic yum source for php-fpm
yum: name=https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
- name: Ensure nginx is at the latest version
yum: pkg=nginx state=latest
- name: Write the nginx config file
template: src=roles/wordpress/templates/nginx.conf.j2 dest=/etc/nginx/nginx.conf
- name: Create nginx root folder
file: 'path={{ root }} state=directory owner={{ user }} group={{ user }} mode=0755'
- name: Copy info.php to remote
copy: 'remote_src=no src=roles/wordpress/files/info.php dest=/data/www/info.php mode=0755'
- name: Restart nginx service
service: name=nginx state=restarted
- name: Setup php-fpm
command: 'yum install -y php70w php70w-fpm php70w-common php70w-mysql php70w-gd php70w-xml php70w-mbstring php70w-mcrypt warn=False'
- name: Restart php-fpm service
service: name=php-fpm state=restarted
- name: Copy php-fpm config file to remote
copy: 'remote_src=no src=roles/wordpress/files/www.conf dest=/etc/php-fpm.d/www.conf mode=0755 owner={{ user }} group={{ user }} force=yes'
- name: Restart php-fpm service
service: name=php-fpm state=restarted
- name: Run the health check locally
shell: "sh roles/wordpress/files/health_check.sh {{ server_name }} {{ port }}"
delegate_to: localhost
register: health_status
- debug: msg="{{ health_status.stdout }}"
- name: Setup mariadb(mysql)
command: "yum install -y mariadb mariadb-server warn=False"
- name: Backup current www folder
shell: 'mv {{ root }} {{ backup_to }}'
- name: Close git ssl verification
shell: 'git config --global http.sslVerify false'
- name: Clone WordPress repo to remote
git: "repo=http://{{ gitlab_user | urlencode }}:{{ gitlab_pass | urlencode }}@192.168.2.200:8091/root/wordpress-project.git dest=/data/www version={{ branch }}"
when: project == 'wordpress'
- name: Change www folder permission
file: "path=/data/www mode=0755 owner={{ user }} group={{ user }}"
九、将源码和脚本提交到Gitlab仓库
# 将wordpress_playbooks文件夹下的文件添加到git管理
git add .
# 将代码提交到本地仓库
git commit -m "First commit"
# 将本地代码提交到远程仓库
git push origin master
十、pipeline任务构建脚本的编写
10.1、新建任务
点击新建任务
填写任务名称和选择任务类型后点击确定。
10.2、编写pipeline脚本
下面为脚本源码，
#!groovy
pipeline {
agent {node {label 'master'}}
environment {
PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/git/bin:"
}
parameters {
choice(
choices: 'dev\nprod',
description: 'Choose deploy envrionment',
name: 'deploy_env'
)
string(name: 'branch', defaultValue: 'master', description: 'Fill in your ansible repo branch')
}
stages {
stage ("Pull deploy code") {
steps {
sh 'git config --global http.sslVerify false'
dir ("${env.WORKSPACE}"){
git branch: 'master', credentialsId: 'edc4ee8c-db9a-4d09-bed6-5747da58d83b', url: 'http://192.168.2.200:8091/root/ansible-playbook-repo.git'
}
}
}
stage ("Check env") {
steps {
sh """
set +x
user=`whoami`
if [ $user == deploy ]
then
echo "[INFO] Current deployment user is $user"
source /home/deploy/.py3-a2.5-env/bin/activate
source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q
echo "[INFO] Current python version"
python --version
echo "[INFO] Current ansible version"
ansible-playbook --version
echo "[INFO] Remote system disk space"
ssh [email protected] df -h
echo "[INFO] Remote system RAM"
ssh [email protected] free -m
else
echo "Deployment user is incorrect, please check"
fi
set -x
"""
}
}
stage ("Ansible deployment") {
steps {
input "Do you approve the deployment?"
dir("${env.WORKSPACE}/wordpress_playbooks") {
echo "[INFO] Start deployment"
sh """
set +x
source /home/deploy/.py3-a2.5-env/bin/activate
source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q
ansible-playbook -i inventory/$deploy_env ./deploy.yml -e project=wordpress -e branch=$branch -e env=$deploy_env
set -x
"""
echo "[INFO] Deployment finished..."
}
}
}
}
}
源码中git部分的credentialsId为下图中的红色框中部分
十一、测试构建
11.1、测试构建
打开jenkins的界面，然后如图点击开始构建。点击后刷新页面，点击左侧构建小圆圈进入到日志输出界面。
由于构建过程中有一个校验，需要在这里确认点击后才会继续构建。
11.2、问题
注意点： 这里如下图出现了ansible的剧本脚本执行的时候出现的git命令不存在的报错。随后去到了testbox目标主机上去执行git --version的命令，发现可以执行。有点懵！！！
在textbox主机的git安装的时候由于在jenkins部分配置git的时候需要安装比较高版本的git。所以在testbox主机上也对git做了升级。但是如下图，升级的git的路径是/usr/local/git。并非在默认的ansible脚本执行的环境变量上。
默认安装的git的路径如下图
这里删除了原先升级的git，然后通过yum install -y git安装了较低版本的git，然后重新构建。构建成功！
11.3、处理WordPress需要的mysql数据库
MySQL如果通过ansible剧本一直去更新会出现问题，所以这里我们需要手动登录testbox目标主机去设置好MySQL。
Centos升级到7以后，MySQL更新为Mariadb
