本文实例讲述了php管理nginx虚拟主机shell脚本，分享给大家供大家参考。具体分析如下：

使用php作为shell脚本是一件很方便的事情。理所当然，我们可以使用php脚本来管理 nginx虚拟主机，下面是笔者的 脚本 文件供各位参考：
复制代码 代码如下:#!/usr/bin/php -q
<?php

start: fwrite(STDOUT,"===========Vhost Script===========\n");
fwrite(STDOUT,"= Choose an operation \n");
fwrite(STDOUT,"= 1.Create 2.Delete 3.Exit\n");
fwrite(STDOUT,"==================================\n");
$operate = trim(fgets(STDIN));
if ( $operate == 1 ){
fwrite(STDOUT,"Please Enter a Domain Name:");
$domain = trim(fgets(STDIN));
$path = "/home/sites/{$domain}";
$nginx_conf = "/etc/nginx/sites/{$domain}";
$nginx_template = "/etc/nginx/template/site_conf";
$apache_conf = "/etc/httpd/conf/httpd.conf";
$conf_str = "";

//变量初始化

if( file_exists($path ) ) exit ("Domain Existed!\n");
else mkdir($path,0700);
if(file_exists($nginx_conf)) exit ("Nginx Config file existed!\n");
else {
$conf_str = file_get_contents( $nginx_template );
}

//目录检测及配置文件拷贝

eval ( "\$conf_str = \"$conf_str\";" );

$succes = file_put_contents($nginx_conf,$conf_str);
if( !$succes ) exit ("Write Config File Fauile!");
else echo "Create Vhost success!\n";
goto start;
//写入配置文件
}
else if ($operate == 2){
$confs_dir = dir("/etc/nginx/sites");
$confs_list = array();
$count = 0;
while ( false !== ( $conf_file = $confs_dir->read() ) ){
if( $conf_file == "." ) continue;
if( $conf_file == ".." ) continue;
if ( is_file( $confs_dir->path ."/". $conf_file) ) {
$confs_list[$count++] = $conf_file;
}
}
echo "Select a site by number which to delete:\n";
if( count( $confs_list ) >0 )
foreach ( $confs_list as $k=>$v ){
echo "{$k}. $v\n";
}
$index = trim(fgets(STDIN));
if( in_array ( $index,array_keys( $confs_list ) ) ){
copy( $confs_dir->path ."/". $confs_list[$index],"/etc/nginx/backup/{$confs_list[$index]}" );
unlink ( $confs_dir->path ."/". $confs_list[$index] );
exec("tar -zcf /home/sites/{$confs_list[$index]}.tar.gz /home/sites/".$confs_list[$index] );
exec("rm -Rf /home/sites/".$confs_list[$index]);
}
//删除指定配置，并保存备份
}
else if( $operate == 3 ) {
exit;
}
else {
exit ("No Operation Selected!");
}
?>
下面是nginx的配置模版
复制代码 代码如下:server {
listen 80;
server_name {$domain};
access_log /var/log/nginx/{$domain}_access_log;
error_log /var/log/nginx/{$domain}_error_log;
root {$path};
#不记录对站点图标访问
location = /favicon.ico {
log_not_found off;
access_log off;
}
#不记录对robots.txt的访问
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
location = / {
try_files @proxy;
}
location / {
index index.htm index.html index.php;
try_files \$uri @proxy;
}
#匹配html
location ~* \.(html|htm)$ {
expires 30s;
gzip off;
add_header Content-Encoding gzip;
try_files \$uri \$uri/ /wp-content/cache/supercache/\$http_host/\$request_uri/index.html.gz @proxy;
}
#匹配图片、脚本文件等
location ~* \.(jpe?g|gif|png|ico|css|js|flv|swf|avi|zip|rar|svg|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mp3)$ {
expires 30d;
}
#传递给apache
location @proxy {
index index.htm index.html index.php;
proxy_pass http://127.0.0.1:81;
include /etc/nginx/proxy.conf;
}
}

希望本文所述对大家的php程序设计有所帮助。
