0、查看系统信息
编写查看系统信息脚本
vim sysinfo.sh
#!/bin/bash
uname -a && echo '' && \\
cat /etc/centos-release && echo '' && \\
hostnamectl && echo '' && \\
lscpu && echo '' && \\
free -h && echo '' && \\
lsblk && echo '' && \\
df -hT
授权可执行权限
chmod u+x sysinfo.sh
执行脚本
./sysinfo.sh
[root@localhost ~]# ./sysinfo.sh

[root@localhost ~]#
1、安装epel
yum install epel-release -y
2、安装ansible
- 查看是否支持ansible
yum search ansible
[root@localhost ~]# yum search ansible

[root@localhost ~]#
- 安装ansible
yum -y install ansible
3、查看安装版本
ansible --version
[root@localhost ~]# ansible --version
ansible 2.8.5
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/site-packages/ansible
executable location = /usr/bin/ansible
python version = 2.7.5 (default, Aug 7 2019, 00:57:09) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
[root@localhost ~]#
4、查看ansible默认安装目录
[root@localhost ~]# ll /etc/ansible/
total 28
-rw-r--r-- 1 root root 19980 Sep 14 2019 ansible.cfg
-rw-r--r-- 1 root root 1016 Sep 14 2019 hosts
drwxr-xr-x 2 root root 4096 Sep 14 2019 roles
ansible.cfg 是ansible配置文件
hosts 是管理端主机IP
roles 是规则
[root@localhost ~]# cd /etc/ansible/
[root@localhost ansible]#
[root@localhost ansible]# vim hosts
[root@localhost ansible]#
[root@localhost ansible]# vim ansible.cfg
5、测试一下ansible是否能够使用
注意细节：
这个时候不能再root用户下执行下面的命令，需要切换到普通用户下去执行
[coding@localhost ~]$ ansible all -m ping
[coding@localhost ~]$ ansible all -m command -a "free -h"
[coding@localhost ~]$ ansible all -m command -a "iostat"
[coding@localhost ~]$ ansible all -m command -a "cat /etc/centos-release"
下期预告：在鲲鹏架构openEuler上部署ansible
敬请期待！
都看到最后啦，点个赞支持一下再走呗！
