7 ping 模块
在ansible中使用ping模块来检测指定主机的连通性
[root@promote ~]# ansible all -m ping
192.168.199.130 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.199.131 | SUCCESS => {
"changed": false,
"ping": "pong"
}
8 yum 模块
ansible中的yum模块负责在被管理主机上安装与卸载软件包，但是需要提前在每个节点配置自己的yum仓库。其中name指定要安装的软件包，还需要带上软件包的版本号，否则安装最新的软件包，使用state指定安装软件包的状态，present,latest用来表示安装，absent表示卸载。
[root@promote ~]# ansible-doc -s yum
- name: Manages packages with the `yum' package manager
yum:
allow_downgrade: # Specify if the named package and version is allowed
to downgrade a maybe
already installed
higher version of that
package.
在web服务器上安装httpd服务：
[root@promote ~]# ansible web -m yum -a 'name=httpd'

[root@web ~]# rpm -q httpd #在web服务器上进行查看
httpd-2.4.6-80.el7.centos.1.x86_64
卸载的命令为ansible web -m yum -a 'name=httpd state=absent' 这里为了我下面的实验就先不卸载了
