ansible创建连接：

客户端（管理节点）

可能需要安装包：

yum install -y libselinux-python

实现ssh免密码登陆管理的服务器

to make sure we haven't added extra keys that you weren't expecting.

测试是否成功：

[apps@anza ~]$ ssh root@192.168.111.131

编辑配置文件

加上：

[nginx_load]
192.168.111.131

测试：

执行带参数的脚本方式：

1先复制到目标服务器：

[apps@anza tmp]$ sudo ansible nginx_load -m copy -a "src=/tmp/Initialize.quan.sh dest=/tmp/Initialize.quan.sh  mode=0755"
192.168.111.131 | SUCCESS => {

}

指定脚本执行（带参数）：

[apps@anza tmp]$ sudo ansible nginx_load  -m shell -a "/tmp/Initialize.quan.sh nginxload.one.bbs 2004 2004 "
