安装

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all
yum makecache
yum install -y ansible

查看ansible版本

[root@k8s-master ~]# ansible --version
ansible 2.9.21
  config file = /etc/ansible/ansible.cfg
  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, Nov 16 2020, 22:23:17) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

通过config file 可以得出默认配置文件的目录

/etc/ansible/ansible.cfg  # ansible 配置文件
/etc/ansible/hosts   # inventorys目录,以后被管节点的服务器都会放在这里

ansible.cfg

[defaults]

# some basic default values...
#inventory      = /etc/ansible/hosts         #主机列表配置文件
#library        = /usr/share/my_modules/    #库文件存放目录
#remote_tmp     = $HOME/.ansible/tmp        #临时python命令存放在远程主机的目录
#local_tmp      = $HOME/.ansible/tmp        #本地主机临时命令执行目录
#forks          = 5                         #默认并发数
#poll_interval  = 15                  
#sudo_user      = root          #默认sudo用户
#ask_sudo_pass = True           #每次执行ansible命令是否询问ssh密码
#ask_pass      = True
#transport      = smart
#remote_port    = 22       
#module_lang    = C
#module_set_locale = True
#host_key_checking = False #检查对应服务器的host_key,建议取消注释
#log_path=/var/log/ansible.log #日志文件,建议启用
module_name = shell #  模块默认模块是 command
