第十六周

1、使用ansible的playbook实现自动化安装httpd

安装ansible服务：

[root@Ansiable ~]# yum install -y ansible

配置ansible跟其他主机之间基于key验证

[root@Ansiable ~]# ssh-keygen

Generating public/private rsa key pair.

Enter file in which to save the key (/root/.ssh/id_rsa):

Created directory '/root/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /root/.ssh/id_rsa.

Your public key has been saved in /root/.ssh/id_rsa.pub.

The key fingerprint is:

SHA256:bAHlfv4EF2vxanwwjlT77C1E0XqR7JRsygOZtTOhSUU root@Ansiable

The key's randomart image is:

+---[RSA 2048]----+

|      ...  .*Eo.o|

|      o  .+o +O.|

|        o  o*+=o.|

|      o . . X=..|

|        S + B.o. |

|      . + B *.  |

|          o *.+  |

|          + o.. |

|            . ...|

+----[SHA256]-----+

[root@Ansiable ~]# ssh-copy-id 192.168.10.4

[root@Ansiable ~]# ssh-copy-id 192.168.10.5

配置ansible主机清单，将需要管控的主机地址添加进去：

[root@Ansiable ~]# vim /etc/ansible/hosts

[webser]

192.168.10.4

192.168.10.5

 编写playbook：

[root@Ansiable playbook]# vim http_install.yml

- hosts: all

  tasks:

  - name: install httpd

    yum: name=httpd state=present

  - name: start httpd

    service: name=httpd state=started

测试playbook：

[root@Ansiable playbook]# ansible-playbook -C http_install.yml

执行playbook：

[root@Ansiable playbook]# ansible-playbook http_install.yml

客户机验证：

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.access

(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

测试机修改hosts文件，进行测试：
