1、使用ansible的playbook實現(xiàn)自動化安裝httpd
yum安裝
yum install ansible -y
配置主機清單
vim /etc/ansible/hosts
[websrvs]
172.16.100.46
172.16.100.47
[app]
172.16.100.48
創(chuàng)建ssh免密鑰登錄
[root@localhost ~]# ssh-keygen
[root@localhost ~]# ssh-copy-id 172.16.100.46
[root@localhost ~]# ssh-copy-id 172.16.100.47
[root@localhost ~]# ssh-copy-id 172.16.100.48
編寫yml文件
[root@localhost playbook]#vim httpd.yml
---
- hosts: app
remote_user: root
tasks:
- name: install
yum: name=httpd
- name: config
copy: src=/data/playbook/httpd.conf dest=/etc/httpd/conf/
notify: restart httpd
- name: service
service: name=httpd state=started enabled=yes
handlers:
- name: restart httpd
service: name=httpd state=restarted
測試安裝
[root@localhost playbook]#ansible-playbook -C http.yml

查看測試機是否啟動HTTP
[root@localhost local]# ss -ntlp
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:* users:(("sshd",pid=5038,fd=3))
LISTEN 0 100 127.0.0.1:25 *:* users:(("master",pid=5573,fd=13))
LISTEN 0 128 :::80 :::* users:(("httpd",pid=24562,fd=4),("httpd",pid=24561,fd=4),("httpd",pid=24560,fd=4),("httpd",pid=24559,fd=4),("httpd",pid=24558,fd=4),("httpd",pid=24557,fd=4))
LISTEN 0 128 :::22 :::* users:(("sshd",pid=5038,fd=4))
LISTEN 0 100 ::1:25 :::* users:(("master",pid=5573,fd=14))
2、建立httpd服務(wù)器，要求提供兩個基于名稱的虛擬主機:
(1)www.X.com，頁面文件目錄為/web/vhosts/x;錯誤日志為
/var/log/httpd/x.err，訪問日志為/var/log/httpd/x.access
(2)www.Y.com，頁面文件目錄為/web/vhosts/y;錯誤日志為 /var/log/httpd/y.err，訪問日志為/var/log/httpd/y.access
(3)為兩個虛擬主機建立各自的主頁文件index.html，內(nèi)容分別為其對應(yīng)的主機名
建立主頁面
[root@localhost ~]# mkdir /web/vhosts/{x,y} -p
[root@localhost ~]# cd /web/vhosts/
[root@localhost vhosts]# echo www.X.com > x/index.html
[root@localhost vhosts]# echo www.Y.com > y/index.html
建立日志文件
[root@localhost vhosts]# cd /var/log/httpd/
[root@localhost httpd]# ls
access_log error_log error_log-20200913
[root@localhost httpd]# touch {x,y}.{err,access}
[root@localhost httpd]# ll
總用量 8
-rw-r--r-- 1 root root 0 9月 18 13:45 x.access
-rw-r--r-- 1 root root 0 9月 18 13:45 x.err
-rw-r--r-- 1 root root 0 9月 18 13:45 y.access
-rw-r--r-- 1 root root 0 9月 18 13:45 y.err
編寫配置文件
[root@localhost httpd]# vim /etc/httpd/conf.d/test.conf
<virtualhost *:80>
documentroot "/web/vhosts/x"
servername www.X.com
customlog "/var/log/httpd/x.assess" combined
errorlog "/var/log/httpd/x.err"
<Directory "/web/vhosts/x">
Require all granted
</Directory>
</virtualhost>
<virtualhost *:80>
documentroot "/web/vhosts/y"
servername www.Y.com
customlog "/var/log/httpd/y.assess" combined
errorlog "/var/log/httpd/y.err"
<Directory "/web/vhosts/y">
Require all granted
</Directory>
</virtualhost>
檢測語法是否正常
[root@localhost httpd]# httpd -t
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK
[root@localhost conf]# systemctl start httpd
增添解析配置
[root@localhost ~]# vi /etc/hosts
172.16.100.47 www.X.com www.Y.com
檢測
[root@localhost ~]# curl www.X.com
www.X.com
[root@localhost ~]# curl www.Y.com
www.Y.com
查看日志文件
[root@localhost ~]# tail -f /var/log/httpd/x.access
[root@localhost ~]# tail -f /var/log/httpd/y.access
