1、基础配置

1.1、环境

主机配置
ansible版本：2.7.4
控制端：centos7.4，IP：192.168.1.213，主机名：operation
被控制端：
centos6.5，IP：192.168.1.216，主机名：master；
centos6.5，IP：192.168.1.217，主机名：slave
centos7.3，IP：192.168.1.214，主机名：lzcx

# 系统设置 # centos6.5 service iptables stop chkconfig iptables off sed -i '/^SELINUX=/s/enforcing/disabled/' /etc/selinux/config setenforce Permissive # 控制端 sed -i 's/localhost.localdomain/master/' /etc/hosts # 被控制端 sed -i 's/localhost.localdomain/slave/' /etc/hosts # centos7.4 systemctl stop firewalld systemctl disable firewalld sed -i '/^SELINUX=/s/enforcing/disabled/' /etc/selinux/config # 3台机器重启 shutdown -r now # 安装常命令 yum install wget vim lrzsz gcc xz -y

控制端安装python3.7和ansible

# 依赖安装 yum -y install epel-release yum -y install openssl openssl-devel openssl-static python-pip python-devel zlib-devel libffi-devel python-rpm-macros # 下载python3.7 wget -c https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz tar -Jxf Python-3.7.0.tar.xz mkdir -p /usr/local/python3 cd ./Python-3.7.0 ./configure --prefix=/usr/local/python3/ make make install ln -s /usr/local/python3/bin/python3 /usr/bin/python3 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3 # 安装ansible pip3 install ansible

1.2、创建ansible管理用户

生产环境中，不允许root通过ssh登录，所以选择一个普通用户做ansible的管理账户。这里的环境是新主机，刚刚申请后只有一个root用户，以下脚本完成ansible新建管理用户和实现管理用户的密钥分发，注意需要安装sshpass，脚本会检查，默认所有机器的root密码一样。

以下是批量部署，创建ansible用户、密钥分发和实现sudo权限，可以自定义用户名和密码

1.3、配置清单

下文中组名为 yuhui 的修改为 lzcx ，ip不变

[monitor] 192.168.1.213[centos6] 192.168.1.[216:217][lzcx] 192.168.1.214# 额外添加测试机器 [mysql] 192.168.1.20 192.168.1.21[gzyk] 192.168.1.130 192.168.1.38[dgyk] 192.168.1.162[uim] 192.168.1.98[yhgl] 192.168.1.172
