最近在安装ansible，安装后命令找不到
[root@center ansible-2.7.5]# python setup.py install
安装后 查看相关版本
[root@center ansible-2.7.5]# ansible --version -bash: ansible: command not found
查看可执行文件目录为
[root@center ansible-2.7.5]# /usr/local/bin/ansible --version ansible 2.7.5 config file = None configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/local/lib/python2.7/site-packages/ansible-2.7.5-py2.7.egg/ansible executable location = /usr/local/bin/ansible python version = 2.7.8 (default, Jan 9 2019, 14:25:24) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] [root@center ansible-2.7.5]# echo $PATH /usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
当前PATH 并没有/usr/local/bin，因此需要将/usr/local/bin添加到环境变量中
下面列出三种添加方法
1、直接用export命令：
export PATH=/usr/local/bin:$PATH [root@center ansible-2.7.5]# echo $PATH /usr/local/bin:/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin 但是这种方法只会对当前用户及当前命令行窗口生效，退出后就会丢失
2、编辑修改.bashrc文件:
vim /root/.bashrc #在最后一行添上： export PATH=/usr/local/bin:$PATH 这种方法只会对当前用户生效，需重启系统
3、编辑修改profile文件:
vim /etc/profile export PATH=/usr/local/bin:$PATH 这种方法对所有用户生效，需重启系统 所以我们配置时需要结合1-2或者1-3 配置完之后再次执行ansible [root@center ansible-2.7.5]# ansible --version ansible 2.7.5 config file = None configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/local/lib/python2.7/site-packages/ansible-2.7.5-py2.7.egg/ansible executable location = /usr/local/bin/ansible python version = 2.7.8 (default, Jan 9 2019, 14:25:24) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]
