ansible通过yum/dnf模块给受控机安装软件(ansible2.9.5)

一,使用yum/dnf模块要注意的地方:

使用dnf软件安装/卸载时,需要有root权限,

所以要使用become参数

二,用yum模块卸载软件

#name:软件的名字

#state: 状态,取值有:present:默认的,表示为安装
                           lastest: 安装为最新的版本
                           absent:表示删除

[liuhongdi@centos8 ~]$ ansible yujian -m yum -a 'name=screen state=absent' --become  --become-method=sudo --become-user=root
121.122.123.47 | CHANGED => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": true,
"msg": "",
"rc": 0,
"results": [
"Removed: screen-4.6.2-10.el8.x86_64"
]
}

三,用yum模块安装软件:

[liuhongdi@centos8 ~]$ ansible yujian -m yum -a 'name=screen' --become  --become-method=sudo --become-user=root
121.122.123.47 | CHANGED => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": true,
"msg": "",
"rc": 0,
"results": [
"Installed: screen-4.6.2-10.el8.x86_64"
]
}

四,安装软件时关闭gpg验证

#disable_gpg_check 值为yes时,禁用gpg验证

[liuhongdi@centos8 ~]$ ansible yujian -m yum -a 'name=screen disable_gpg_check=yes' --become  --become-method=sudo --become-user=root

说明:如果对应的 yum 源没有开启 gpg 验证,则需要将此参数的值设置为 yes,否则会报错而无法进行安装

因为这里要和server交互

五,安装软件时指定来源库

#enablerepo 指定安装时的来源repo

[liuhongdi@centos8 ~]$ ansible yujian -m yum -a 'name=screen enablerepo=epel' --become  --become-method=sudo --become-user=root

六,查看centos的版本:

[liuhongdi@centos8 ~]$ cat /etc/redhat-release
CentOS Linux release 8.1.1911 (Core)
