今天下午寫了一個簡單的一鍵式自動虛擬機器主機搭建shell指令碼，指令碼實現自動設定nginx虛擬機器主機，自動建立ftp賬戶，自動建立資料庫，使用者，並自動實現mysql自動定時備份，日誌切割，程式備份。
這裡因為其他原因，就將備份機制去掉了，代碼如下。
首先需要一個基礎的nginx虛擬機器主機設定檔，一般情況下，我們配置虛擬機器主機都是建一個vhost目錄，這裡我在/etc/nginx下面建了一個default.conf檔案
| 代碼如下 |

log_format #host# '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
server {
listen 80;
server_name #host#;
root #hosts#/#host#/html;
index index.html index.htm index.php default.html default.htm default.php;
location / {
autoindex on;
}
error_page 404 /404.html;
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#注意這一句
location ~ ^(.+.php)(.*)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
# redirect server error pages to the static page /50x.html
access_log #hosts#/#host#/log/#host#.log #host#;
} |
注意裡面一些關鍵路徑，我用特殊字元組合來表示，這樣方便我們添加虛擬注意的時候進行匹配替換
host.sh指令碼如下

#/bin/sh

看一下運行效果，sh host.sh
| 代碼如下 |
複製代碼 |
[root@localhost nginx]# sh 2.sh
1.add ftp user
please input websit:
hhh.com
add user,please input user name:
hhh
|
更改使用者 hhh 的密碼 。
新的 密碼：
無效的密碼： WAY 過短
無效的密碼： 是迴文
重新輸入新的 密碼：
passwd： 所有的身分識別驗證令牌已經成功更新。

mkdir:/var/www/html/hhh.com/html /var/www/html/hhh.com/bak /var/www/html/hhh.com/log
mkdir:/var/www/html/hhh.com/bak/code /var/www/html/hhh.com/bak/sql
ok,add user success!name=hhh,password=youwrite
If you need a database, please enter a database name, if not required, blank can be
hhh
please input dbuser
hhh
please input dbpwd
hhh
input root pwd
123456
2.To configure nginx
config nginx success
3.add mysql user database
ok,finish!
[root@localhost nginx]#

系統會逐個詢問輸入參數，並且參數是先統一填完，然後程式進行執行，避免中間不小心輸入錯誤無法修改，然後如果無需建立資料庫，那麼database參數不輸入即可。
