ansible批量添加巡检服务器
大概思路图
步骤一：
添加ansible主机清单
vim /etc/ansible/hosts
查看安装版本
# ansible --version
ansible 2.9.6
配置文件路径config file = /etc/ansible/ansible.cfg
查询模块路径configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/site-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.5 (default, Aug 7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
首先配置不检测对方主机公钥
# vim ansible.cfg
[defaults]
host_key_checking = False #取消注释
二、playbook 批量推送
编写playbook文件
- hosts: ceshi
user: root
gather_facts: false #是否执行setup模块，搜集对方机器的信息
vars_files:
- /ansible/foo.yml # 设置用户名密码,设置你传输
tasks:
- name: Set authorized key taken from file
authorized_key: # 发送公钥的模块
user: root # 给这个用户发送公钥
state: present
key: "{
{ lookup('file', '/root/.ssh/id_rsa.pub') }}" # 发送本地用户的公钥路径
编辑foo.yml文件 设置密码
# vim foo.yml
ansible_ssh_pass: 1
#这里我是密码全为1 ，如果不是 请自行百度： 多主机且密码不一样时如何书写yml文件
执行结果
root@192:/ansible# ansible-playbook --syntax-check update.yml #检测语法
[WARNING]: Found both group and host with same name: tomcat
playbook: update.yml
root@192:/ansible# ansible-playbook update.yml #执行语法
创建巡检目录
tasks:
- name: 创建巡检目录
shell: mkdir /xunjian
三、定义发送巡检日志脚本
创建引用变量文件
/ansible/update #当前目录
vim files.yml #创建文件，定义变量
- src_path: "/ansible/update/scp.sh"
- dest_path: "/xunjian/"
创建巡检日志脚本
root@192:/ansible/update# vim scp.sh
# !/bin/sh
#echo "$processid 请管理员注意,99.88 拼接服务暂停服务 " >>monitor.log
#echo 启动了 | mailx -s "test" [email protected] -f [email protected]
#cd /email/file/error
filelist=`ls /xunjian/log`
for file in $filelist
do
echo $file
scp /xunjian/log/$file root@xxxx:/xunjian/
rm -rf /xunjian/log/$file
done
root@192:/ansible/update# chmod +x scp.sh
ansible-playbook剧本内容
- hosts: ceshi
user: root
gather_facts: false #是否执行setup模块，搜集对方机器的信息
vars_files:
- /ansible/update/foo.yml # 设置用户名密码,设置你传输
tasks:
- name: 执行传输公钥
authorized_key: # 发送公钥的模块
user: root # 给这个用户发送公钥
state: present
key: "{
{ lookup('file', '/root/.ssh/id_rsa.pub') }}" # 发送本地用户的公钥路径
tasks:
- name: 创建巡检目录
shell: mkdir /xunjian
vars_files: #自定义变量 调用变量文件
- /ansible/update/files.yml
tasks:
- name: 传输巡检日志脚本
copy: copy: src={
{
src_path }} dest={
{
dest_path }}
四、定义发送巡检脚本
创建引用变量文件
我这里是直接放在刚才的变量文件里面拉，改了一下名称
/ansible/update #当前目录
vim files.yml #创建文件，定义变量
#第一个是 巡检的日志，传输到控制节点脚本spc
- src_path: "/ansible/update/scp.sh"
- dest_path: "/xunjian/"
#第二个是巡检的脚本
- src_xunjian: "/ansible/update/xunjian.sh"
- dest_xunjian: "/xunjian/"
创建巡检脚本
vim xunjian.sh
#!/bin/bash
#主机信息每日巡检
IPADDR=$(ifconfig eth0|grep 'inet addr'|awk -F '[ :]' '{print $13}')
#环境变量PATH没设好，在cron里执行时有很多命令会找不到
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
source /etc/profile
[ $(id -u) -gt 0 ] && echo "请用root用户执行此脚本！" && exit 1
centosVersion=$(awk '{print $(NF-1)}' /etc/redhat-release)
VERSION="2017.08.22"
#日志相关
PROGPATH=`echo $0 | sed -e 's,[\\/][^\\/][^\\/]*$,,'`
[ -f $PROGPATH ] && PROGPATH="."
LOGPATH="$PROGPATH/log"
[ -e $LOGPATH ] || mkdir $LOGPATH

使用sed流编译器
我们这里需求是修改一下巡检的脚本，让他根据巡检的服务器ip定义巡检日志名称
sed -i 's#192.168.2.204#192.168.2.64#' /ansible/update/xunjian.sh
查看这里已经更改

解决没有执行权限
copy模块的作用就是拷贝文件，将ansible主机上的文件拷贝到远程主机中。
src参数 ：用于指定需要copy的文件或目录
dest参数 ：用于指定文件将被拷贝到远程主机的哪个目录中，dest为必须参数
content参数 ：当不使用src指定拷贝的文件时，可以使用content直接指定文件内容，src与content两个参数必有其一，否则会报错。
force参数 : 当远程主机的目标路径中已经存在同名文件，并且与ansible主机中的文件内容不同时，是否强制覆盖，可选值有yes和no，默认值为yes，表示覆盖，如果设置为no，则不会执行覆盖拷贝操作，远程主机中的文件保持不变。
backup参数 : 当远程主机的目标路径中已经存在同名文件，并且与ansible主机中的文件内容不同时，是否对远程主机的文件进行备份，可选值有yes和no，当设置为yes时，会先备份远程主机中的文件，然后再将ansible主机中的文件拷贝到远程主机。
owner参数 : 指定文件拷贝到远程主机后的属主，但是远程主机上必须有对应的用户，否则会报错。
group参数 : 指定文件拷贝到远程主机后的属组，但是远程主机上必须有对应的组，否则会报错。
mode参数 : 指定文件拷贝到远程主机后的权限，如果你想将权限设置为"rw-r--r--"，则可以使用mode=0644表示，如果你想要在user对应的权限位上添加执行权限，则可以使用mode=u+x表示
拷贝单个文件到目标服务器 实例
[root@Jenkins copymodule]# cat copy.yml
---
- hosts: all
remote_user: root
gather_facts: false
tasks:
- name: "复制主机上的文件到目标服务器上"
copy:
src: "/root/ansible/luyan/copymodule/copytest1.txt"
dest: "/opt/copymodule"
owner: root
group: root
mode: 755
拷贝多个文件到目标服务器
[root@Jenkins copymodule]# cat copyduogewenjian.yml
---
- hosts: all
remote_user: root
gather_facts: false
tasks:
- name: "复制主机上的文件到目标服务器上"
copy:
src: "{
{ item.src }}"
dest: "{
{ item.dest }}"
owner: root
group: root
mode: 755
with_items:
- {
src: "/root/ansible/luyan/copymodule/copytest1.txt", dest: "/opt/copymodule" }
- {
src: "/root/ansible/luyan/copymodule/copytest2.txt", dest: "/opt/copymodule" }
- {
src: "/root/ansible/luyan/copymodule/copytest3.txt", dest: "/opt/copymodule" }
则会报错。
group参数 : 指定文件拷贝到远程主机后的属组，但是远程主机上必须有对应的组，否则会报错。
mode参数 : 指定文件拷贝到远程主机后的权限，如果你想将权限设置为"rw-r–r–"，则可以使用mode=0644表示，如果你想要在user对应的权限位上添加执行权限，则可以使用mode=u+x表示
