ansible自动化管理剧本方式一键完成三大服务器基础配置
环境准备：五台服务器：管理机m01:172.16.1.61,两台web服务器172.16.1.7，172.16.1.8，nfs存储服务器172.16.1.31，备份服务器rsync172.16.1.41
要求实现：nfs服务器共享目录/data给两台web服务器
三台服务器可以通过定时任务 备份到备份服务器rsync
实时监控nfs/data目录，并实时备份到备份服务器rsync
开整：
一、配置管理机m01
1.下载基本软件
cd /server/scripts
vim benjipeizhi.sh
#!/bin/sh
yum install oppenssh oppenssl -y &&\
systemctl restart sshd &&\
systemctl enable sshd &&\
yum install opel-releare -y &&\
yum install ansible -y &&\
yum install libselinux-python -y
3.编辑主机列表，方便批量管理（1代表服务端，2代表客户端）
vim /etc/ansible/hosts
[oldboy]
172.16.1.7
172.16.1.8
172.16.1.31
172.16.1.41
[rsync]
172.16.1.41
[rsync2]
172.16.1.7
172.16.1.8
172.16.1.41
[nfs1]
172.16.1.31
[nfs2]
172.16.1.7
172.16.1.8
[sersync]
172.16.1.31
4.创建并分发公钥，实现免密连接
vim fenfa.sh
#!/bin/sh
ssh-keygen -f ~/.ssh/id_rsa -P '' -q
for ip in 7 8 31 41
do
sshpass -p123456 ssh-copy-id -i ~/.ssh/id_rsa.pub "-o StrictHostKeyChecking=no" 172.16.1.$ip
done
5.下载sersync实时监控软件（本人是从桌面直接拉虚拟机的）
解压然后编辑配置文件(适当修改部分即可)这一个是通过copy模块远程复制过去的，在本机编辑好
vim /server/tools/appliction/sersync/conf
<?xml version="1.0" encoding="ISO-8859-1"?>
<head version="2.5">
<host hostip="localhost" port="8008"></host>
<debug start="false"/>
<fileSystem xfs="false"/>
<filter start="false">
<exclude expression="(.*)\.svn"></exclude>
<exclude expression="(.*)\.gz"></exclude>
<exclude expression="^info/*"></exclude>
<exclude expression="^static/*"></exclude>
</filter>
<inotify>
<delete start="true"/>
<createFolder start="true"/>
<createFile start="false"/>
<closeWrite start="true"/>
<moveFrom start="true"/>
<moveTo start="true"/>
<attrib start="false"/>
<modify start="false"/>
</inotify>
<sersync>
<localpath watch="/data">
<remote ip="172.16.1.41" name="backup"/>
<remote ip="172.16.1.41" name="oldboy"/>
<!--<remote ip="192.168.8.39" name="tongbu"/>-->
<!--<remote ip="192.168.8.40" name="tongbu"/>-->
</localpath>
rsync服务端配置文件也是通过copy模块远程推送，所以现在本机编辑好
vim /etc/rsyncd.conf
#!/bin/sh
uid = rsync
gid = rsync
use chroot = no
fake super = yes
max connections =200
timeout = 600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
read only = false
list = false
list = false
hosts allow = 172.16.1.0/24
auth users = rsync_backup
secrets file = /etc/rsync.password
[backup]
comment = welcome to oldboyedu backup!
path = /backup/
6.连接测试
sh fenfa.sh 执行创建并分发公钥的脚本
ansible oldboy -m command -a "ifconfig" 显示四台服务器IP说明远程连接成功
重点来啦，写剧本
在/etc/ansible下创建yaml目录，剧本名为one.yml
mkdir -p /etc/ansible/yaml
vim one.yml
