192.168.1.101
192.168.1.102

3.在/etc/ansible/roles中创建nginx目录结构
|

|
[root@Centos roles]
# mkdir -p/etc/ansible/roles/nginx/{defaults,files,handlers,meta,tasks,templates,vars}
|
整体目录结构:

4.执行ansible-playbook进行安装:

[root@Centos files]
# cd /etc/ansible/
[root@Centos ansible]
# ls
ansible.cfg hosts roles webservice.yml
[root@Centos ansible]
# ansible-playbook webservice.yml
|
安装成功!
5.测试
由于webserver两个节点安装完没有启动脚本，我们从ansible主机上拷贝一下启动脚本：
|

|
[root@Centos ansible]
# scp /etc/rc.d/init.d/nginx root@192.168.1.101:/etc/rc.d/init.d/
[root@Centos ansible]
# scp /etc/rc.d/init.d/nginx root@192.168.1.102:/etc/rc.d/init.d/
