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)
