Linux之ansible模块使用大全（blockinfile,lineinfile,unarchive,archive,cron,user,group,yum_repository等）_ansible 写入内容

1.blockinfile模块使用： 在rhce上文件ansible.txt文件中写入内容 ansible

然后使用blockinfile模块，在文件中插入内容 blockinfile insert content

然后插入内容 blockinfile with marker 且使用指定标记: marker=#{mark}test

在blockinfile insert content之前插入 insertbefore

在blockinfile insert content之后插入 insertafter

删除其中一行内容

2.lineinfile模块使用 向node节点上文件 ansible.txt2文件如插入内容 lineinfile insert content

删除lineinfile insert content

重新插入lineinfile insert content

在之前插入： insertbefore

在它之后插入: insertafter

插入：Hello ansible,Hiiii

文件中的"Hello ansible,Hiiii"替换成"Hiiii"(使用正则表达式和backrefs)

3.unarchive模块使用 将node主机上的包解压

将server主机上的包解压到node主机且设置权限为644

4.archive模块使用 将node上的目录进行压缩

5.cron模块 在node上为student用户设置周一到周五早上的9:00输出闹钟到/root/alarm_cron

6.user模块 创建用户

删除用户

7.group模块 创建组

删除组

8.yum_repository 设置两个软件仓库BaseOS和APPStream(本地yum源的配置)到文件my.repo

9.yum/dnf模块 安装软件 lrzsz
