测试
1、对单台主机执行命令
[[email protected] ansible]# ansible 192.168.1.132 -m command -a ‘ifconfig‘
2、对全部主机执行命令
[[email protected] ansible]# ansible all -m command -a ‘ifconfig‘
3、对指定主机组执行下载文件命令
ansible websrvs -a ‘wget -O /tmp/epel-release-latest-7.noarch.rpm http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm‘
注：必须指定文件名
4、对指定主机组创建用户
[[email protected] ansible]# ansible websrvs -m user -a "name=hacluster state=present"
5、对指定主机组删除用户
[[email protected] ansible]# ansible websrvs -m user -a "name=hacluster state=absent"
6、设置计划任务：从ntp服务器上同步所有主机时间
[[email protected] ansible]# ansible all -m cron -a ‘name="sync time from ntpserver" minute="*/10" job="/sbin/ntpdate 192.168.1.62 &> /dev/null"
7、取消所有主机上name="sync time from ntpserver"的计划任务
[[email protected] ansible]# ansible all -m cron -a ‘name="sync time from ntpserver" state=absent‘
8、复制本机上的文件至指定主机组
[[email protected] ansible]# ansible websrvs -m copy -a ‘src=/etc/fstab dest=/tmp/fstab.tmp mode=600‘
9、在所有主机上创建指定目录
[[email protected] ansible]# ansible all -m file -a ‘path=/tmp/testdir state=directory‘
10、对所有主机上的文件创建链接文件
[[email protected] ansible]# ansible all -m file -a ‘path=/tmp/fstab.symlink state=link src=/tmp/fstab.tmp‘
11、强制删除所有主机上的链接文件
[[email protected] ansible]# ansible all -m file -a ‘path=/tmp/fstab.symlink state=absent force=yes‘
12、测试管理主机是否在线
[[email protected] ansible]# ansible all -m ping
13、在指定主机组上用yum安装nginx
[[email protected] ansible]# ansible websrvs -m yum -a ‘name=nginx state=latest‘
14、在指定主机组上启动nginx并设定开机启动
[[email protected] nginx]# ansible websrvs -m service -a ‘name=nginx state=started enabled=yes‘
15、在指定主机组上停止nginx并取消开机启动
[[email protected] nginx]# ansible websrvs -m service -a ‘name=nginx state=stopped enabled=no‘
16、在指定主机组上添加centos用户，并设定密码为centos
[[email protected] nginx]# ansible websrvs -m user -a ‘name=centos state=present‘
[[email protected] nginx]# ansible websrvs -m command -a ‘echo centos | passwd --stdin centos‘ #错误，这里不能使用command,应使用shell，command命令不支持管道以下面语句为准
[[email protected] nginx]# ansible websrvs -m shell -a ‘echo centos | passwd --stdin centos‘
17、在指定主机组上执行本地shell脚本
[[email protected] ~]# vim /tmp/test.sh
#!/bin/bash
#
echo "$(hostname) ansible is good." > /tmp/ansible.txt
[[email protected] ~]# ansible websrvs -m script -a ‘/tmp/test.sh‘
18、取得指定主机组上的相关信息
[[email protected] ~]# ansible websrvs -m setup
