第十六周运维作业

1、使用ansible的playbook实现自动化安装httpd

环境主控端192.168.47.154 ，被控端192.168.47.{1，2}7

安装ansible 软件包,关闭selinux;firewalld;date 时间同步

[root@centos7 ~]# yum install ansible

[root@centos7 ~]# mkdir /data/playbook/

[root@centos7 ~]# vim /data/playbook/httpd.yml

---

 - hosts: websrvs

   remote_user: root

 

   tasks:

     - name: install

       yum: name=httpd

     - name: config

       shell: sed -i 's/Listen .*/^Listen 9527/' /etc/httpd/conf/httpd.conf

     - name: service

       service: name=httpd state=started enabled=yes

：wq

[root@centos7 ~]# ansible-playbook /data/playbook/httpd.yml --check –C 检查不操作

 

[root@centos7 ~]# ansible-playbook /data/playbook/httpd.yml  执行

 

成功

[root@centos7 playbook]# ansible websrvs -m shell  -a "ss -nult "  验证

[root@centos7 playbook]# ansible websrvs -m shell  -a "systemctl status httpd "

[root@centos7 playbook]# ansible websrvs -m shell  -a "cat /etc/httpd/conf/httpd.conf|grep Listen " 查看结果

  

2、建立httpd服务器，要求提供两个基于名称的虚拟主机: 

(1)www.X.com，页面文件目录为/web/vhosts/x;错误日志为/var/log/httpd/x.err，访问日志为/var/log/httpd/x.acces 

(2)www.Y.com，页面文件目录为/web/vhosts/y;错误日志为 /var/log/httpd/www2.err，访问日志为/var/log/httpd/y.access

(3)为两个虚拟主机建立各自的主页文件index.html，内容分别为其对应的主机名

服务端192.168.47.17 ，环境安装httpd

[root@centos7 ~]# mkdir -pv /web/vhosts/{x,y}

[root@centos7 ~]# echo www.X.com > /web/vhosts/x/index.html
[root@centos7 ~]# echo www.Y.com > /web/vhosts/y/index.html

[root@centos7 ~]# vim /etc/httpd/conf.d/test.conf

<virtualhost *:80>
documentroot /web/vhosts/x
CustomLog "/var/log/httpd/x.access" combined
ErrorLog "/var/log/httpd/x.err"
servername www.X.com
<Directory "/web/vhosts/x">
      Require all granted
      AllowOverride ALL
</Directory>

</virtualhost>

<virtualhost *:80>
documentroot /web/vhosts/y
CustomLog "/var/log/httpd/y.access" combined
ErrorLog "/var/log/httpd/www2.err"
servername www.Y.com
<Directory "/web/vhosts/y">
      Require all granted
</Directory>
</virtualhost>

：wq  保存退出

[root@centos7 /]# systemctl restart httpd   服务端重启httpd服务

[root@centos7 ~]# vim /etc/hosts   在客户端配置hosts文件

添加一条：

192.168.47.17 www.X.com www.Y.com

验证：

[root@centos7 ~]# curl www.X.com

[root@centos7 ~]# curl www.Y.com
