ansible安装及基本配置

准备

• 服务器安装python
• 服务器安装epel源
  安装ansible需要用epel源，故需要安装

[root@liuqin yum.repos.d]# yum list | grep epel-release
epel-release.noarch                      7-12                          epel     
[root@liuqin yum.repos.d]# yum install -y epel-release

Complete!

在/etc/yum.repos.d下可看到增加了epel源

基本配置

主要配置文件有两个：

• /etc/ansible/ansible.cfg
  ansible.cfg是基本配置文件，可用默认的，修改以下几个配置：

log_path = /var/log/ansible.log
hostfile = /home/ansible/hosts
host_key_checking = False

• /etc/ansible/hosts
  hosts为节点管理文件，主要配置需要ansible远程操作的服务器，hosts文件配置类似如下格式：

[portal]
IP ansible_ssh_user=user_name ansible_ssh_pass=user_passwd

PS：特别要注意一下hosts文件为严格的yaml格式，格式稍有差池就无法正常使用
