3.Ansible playbook实现apache批量部署,并对不同主机提供以各自IP地址为内容的index.html
准备：
(1)到https://mirrors.tuna.tsinghua.edu.cn/查询各个软件的现有版本。
(2)实现ansible主机连接互联网。
1.实现ansible主机与其它机器的基于key验证,ansible检查服务端到远程主机的健康性，准备hosts清单。
[root@ansible ~]# cat ssh_key.sh
#!/bin/bash
IPLIST="
10.0.0.8
10.0.0.6
10.0.0.5
"
rpm -q sshpass &> /dev/null || yum -y install sshpass
[ -f /root/.ssh/id_rsa ] || ssh-keygen -f /root/.ssh/id_rsa -P ''
export SSHPASS=123456789
for IP in $IPLIST;do
{ sshpass -e ssh-copy-id -o StrictHostKeyChecking=no $IP; } &
done
Wait
[root@ansible ~]# ./ssh_key.sh
[root@ansible ~]# ansible all -m ping
10.0.0.8 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
[root@ansible ~]# cat /etc/ansible/hosts
[websrvs]
10.0.0.8
2.编写playbook剧本
[root@ansible ~]# cat install_httpd.yml

3. 准备模版目录及相关文件
实验中，install_httpd.yml在放在哪里，我们就以此为准建立tmplates目录，并把xxxx.j2的模版文件放在tmplates目录下。
例如：
[root@ansible ~]# tree
.
├── install_httpd.yml
├── ssh_key.sh
└── templates
└── httpd.service.j2
install_httpd.yml和 templates处于一个目录下，而hppt.service.j2在template下。
[root@ansible ~]# cat ./templates/httpd.service.j2
