pip安装ansible

因为我的Linux的是CentOS Linux release 7.3.1611 (Core)，使用的ali仓库源。

我在yum安装的ansible是

[root@node4 ~]# ansible --version
ansible 2.3.2.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides
  python version = 2.7.5 (default, Nov  6 2016, 00:28:07) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

由于要使用playbook roles模板自动安装nginx，但该版本存在着BUG，所以只能降到ansible 1.9版本（经过亲测，可以使用）。

所以使用python-pip 安装 ansible1.9版本

yum install -y python-pip
pip install ansible==1.9.1

但在pip install ansible==1.9.1,出现pip版本过低的问题。

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
[root@node4 src]# 

只需将其升级即可

[root@node4 src]# pip install --upgrade pip

如果直接使用pip安装（在此之前为安装过ansible）

pip install ansible==1.9.1

会出现下列问题

compilation terminated.
    error: command 'gcc' failed with exit status 1

即使安装成功也找不到配置文件

[root@node4 ansible]# find / -name ansible
/usr/bin/ansible
/usr/lib/python2.7/site-packages/ansible

这是最绝望的！！！！

所以先使用yum 安装一次ansibel再使用pip安装ansible1.9版本

yum install -y ansible

并且查看/etc/ansible是否存在这些配置文件

[root@node4 ansible]# ls /etc/ansible/
ansible.cfg  hosts  roles

[root@node4 ~]# ansible --version
ansible 2.3.2.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = Default w/o overrides
  python version = 2.7.5 (default, Nov  6 2016, 00:28:07) [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

如果这些文件存在就可以使用

大大的Successfully！！！开心

Successfully installed ansible-1.9.1

查看此时的版本

[root@node4 ~]# ansible --version
ansible 1.9.1
  configured module search path = None

这就成功安装了ansible 1.9版本，哈哈！！！
