一：集中式编写lnmp剧本

vim /etc/ansible/lnmp.yml

- name: lnmp play
  hosts: dbservers
  remote_user: root
 
  tasks:
  - name: perpare condifure
    copy: src=/etc/yum.repos.d/nginx.repo dest=/etc/yum.repos.d/nginx.repo
  - name: install nginx
    yum: name=nginx state=latest
  - name: start nginx
    service: name=nginx state=started enabled=yes
    
  - name: install mysql
    yum: name=mysql57-community-release-el7-10.noarch.rpm state=latest
  - name: modify file
    replace:
      path: /etc/yum.repos.d/mysql-community.repo
      regexp: 'gpgcheck=1'
      replace: 'gpgcheck=0'
  - name: install mysql-community-server
    yum: name=mysql-community-server state=latest
  - name: start mysql
    service: name=mysqld state=started enabled=yes
 
  - name: add yum file
    command: 'wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm -P /etc/yum.repos.d' - name: rpm epel
    command: 'rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm'
  - name: rpm el7
    command: 'rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm'
  - name: install php
    command: 'yum install -y php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache'
  - name: start php-fpm
    service: name=php-fpm state=started  enabled=yes
  - name: copy configure
    copy: src=/usr/local/nginx/conf/nginx.conf dest=/etc/nginx/conf.d/default.conf
  - name: restart nginx
    service: name=nginx state=started enabled=yes

二：分布式安装lnmp

1、nginx 配置

#创建各个服务的节点
vim /etc/ansible/hosts

[webservers]
192.168.231.102

[dbservers]
192.168.231.103

[phpservers]
192.168.231.110

#免交互
ssh-keygen -t rsa
sshpass -p '123456' ssh-copy-id  192.168.231.102 

#创建文件
mkdir /etc/ansible/roles/nginx/{files,templates,tasks,handlers,vars,defaults,meta} -p
mkdir /etc/ansible/roles/mysql/{files,templates,tasks,handlers,vars,defaults,meta} -p
mkdir /etc/ansible/roles/php/{files,templates,tasks,handlers,vars,defaults,meta} -p
 
touch /etc/ansible/roles/nginx/{defaults,vars,tasks,meta,handlers}/main.yml
touch /etc/ansible/roles/mysql/{defaults,vars,tasks,meta,handlers}/main.yml
touch /etc/ansible/roles/php/{defaults,vars,tasks,meta,handlers}/main.yml

cd /etc/ansible/roles/nginx/files
 index.php  nginx.repo
#编写php测试文件
 vim /etc/ansible/roles/nginx/files/index.php
<?php
phpinfo();
?>

#编辑nginx配置源
vim /etc/ansible/roles/nginx/files/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

 vim /etc/ansible/roles/nginx/main.yml
- include: "init.yml"
 
- name: copy nginx repo
  copy: src=nginx.repo dest=/etc/yum.repos.d/
- name: install nginx
  yum: name=nginx state=latest
- name: copy index.php
  copy: src=index.php dest=/var/www/html
- name: transmit nginx configuration
  template: src=default.conf.j2 dest=/etc/nginx/conf.d/default.conf
- name: start nginx
  service: name=nginx state=started enabled=yes

vim /etc/ansible/roles/index.php
- name: stop firewalld
  service: name=firewalld state=stopped enabled=no
- name: stop selinux
  command: 'setenforce 0'

vim /etc/ansible/roles/nginx/template/default.conf.j2
server {
    listen       80;
    server_name  localhost;
 
    #access_log  /var/log/nginx/host.access.log  main;
 
    location / {
        root   /var/www/html;
        index  index.php index.html index.htm;
    }
 
    #error_page  404              /404.html;
 
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
 
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           html;
        fastcgi_pass   192.168.321.110:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
        include        fastcgi_params;
    }
 
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
 

  2、mysql配置

vim /etc/ansible/roles/mysql/tasks/init.yml
- name: stop firewalld
  service: name=firewalld state=stopped enabled=no
- name: stop selinux
  command: 'setenforce 0'

vim /etc/ansible/roles/mysql/main.yml
- include: "init.yml"
 
- name: remove mariadb
  shell: 'yum remove mariadb* -y'
- name: wget
  shell: 'wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm -P /etc/yum.repos.d'
- name: install mysql57-community-release-el7-10.noarch.rpm
  yum: name=epel-release
- name: sed
  replace: path=/etc/yum.repos.d/mysql-community.repo regexp="gpgcheck=1" replace="gpgcheck=0"
- name: install mysql-community-server
  yum: name=mysql-community-server
- name: start mysql
  service: name=mysqld.service state=started
- name: passd
  shell: passd=$(grep "password" /var/log/mysqld.log | awk 'NR==1 {print $NF}')
- name: mysql 1
  shell: mysql -uroot -p'passd' --connect-expired-password -e "ALTER USER 'root'@'localhost' IDENTIFIED BY 'admin@123';"
  ignore_errors: true
- name: mysql 2
  shell: mysql -uroot -padminabc@123 -e "grant all privileges on *.* to root@'%' identified by 'admin@123' with grant option;"
  ignore_errors: true

 3、php配置

vim /etc/ansible/roles/php/tasks/init.yml
- name: stop firewalld
  service: name=firewalld state=stopped enabled=no
- name: stop selinux
  command: 'setenforce 0'


vim /etc/ansible/rolesphp/tasks/main.yml
- include: "init.yml"
 
- name: install yum repo
  shell: "rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm && rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm"
  ignore_errors: true
- name: install php
  command: 'yum install -y php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache'
- name: add user
  user:
    name: php
    shell: /sbin/nologin
    system: yes
- name: copy php.ini
  copy: src=php.ini dest=/etc/php.ini
- name: copy www.conf
  copy: src=www.conf dest=/etc/php-fpm.d/www.conf
- name: copy index.php
  copy: src=index.php dest=/var/www/html
- name: start php-fpm
  service: name=php-fpm state=started

- name: nginx play
  hosts: webservers
  remote_user: root
  roles:
    - nginx
- name: mysql play
  hosts: dbservers
  remote_user: root
