ansible测试环境

ip	user	sudo_user	port	usage
192.168.48.81	ansible	root	29922	nagios & ansible control
192.168.48.82	ansible	root	29922	nagios node1 & boston1
192.168.48.83	ansible	root	29922	target host
192.168.48.84	ansible	root	29922	target host
192.168.48.85	ansible	root	29922	nagios node1 & boston2
192.168.48.86	ansible	root	29922	target host
192.168.48.87	ansible	root	29922	target host

需求

1. 81不能直接访问83,84,86,87，可以通过82,85堡垒机变更部署
2. 所有服务器变更ssh端口22->29922，同时禁用root远程登录，允许ansible用户sudo到root
3. sshkey 81->82,85，82->83,84，85->86,87

ssh管理方式测试

# ansible idc1 -u root -k -m ping
SSH password: 

# results
192.168.48.82 | success >> {
    "changed": false,
    "ping": "pong"
}

192.168.48.83 | success >> {
    "changed": false,
    "ping": "pong"
}

192.168.48.84 | success >> {
    "changed": false,
    "ping": "pong"
}

服务器初始化

使用ssh password方式变更运维环境, 包括以下内容

1)建立ansible用户

2)sshd配置

3)sshkey

变更完成后，使用sshkey方式部署应用环境
