系统平台

[scm@192 ~]$ uname -a
Linux 192.168.109.139 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
[scm@192 ~]$
[scm@192 ~]$ cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
[scm@192 ~]$
[scm@192 ~]$

执行上面的两条指令后，可以看到我当前的系统是 CentOS 7.9 系统平台。

系统更新

今天主要是安装 Ansible 工具，Ansible 是一个配置管理和自动化运维工具，是基于 Python 开发，那系统前提也必须要有 Python 工具环境，才能去执行安装。执行安装之前，还是老规矩先更新系统，执行如下指令：

系统更新完成，显示结果如下：

Install    2 Packages
Upgrade  236 Packages
Remove     1 Package

执行安装

下面接着安装 python-pip ，执行指令如下：

[root@192 scm]#
[root@192 scm]# yum install -y python-pip
Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

Loading mirror speeds from cached hostfile
 * base: mirrors.njupt.edu.cn
 * epel: mirror.sjtu.edu.cn
 * extras: mirrors.njupt.edu.cn
 * updates: mirrors.njupt.edu.cn
Package python2-pip-8.1.2-14.el7.noarch already installed and latest version
Nothing to do
[root@192 scm]#
[root@192 scm]#

可以看到直接安装 python-pip 显示 noarch already installed and latest version  是因为缺少了 epel 扩展源，需要先安装这个源再接着安装。

[root@192 scm]
[root@192 scm] yum -y install epel-release
Loaded plugins: fastestmirror, langpacks, product-id, search-disabled-repos, subscription-manager
