一.构建虚拟主机概述
- 利用虚拟主机，不用为每个运行的网站提供一台单独的Nginx服务器或单独运行一组Nginx进程，虚拟主机提供了在同一台服务器、同一组Nginx进程上运行的多个网站的功能
- 与Apache相同，Nginx也可以配置多种类型的虚拟主机，分别是基于域名、基于端口、基于IP地址的虚拟主机
- 使用Nginx搭建虚拟主机服务器时，每个虚拟web站点拥有独立的“server {}”配置段，各自监听的IP地址、端口号段单独指定
二.基于域名的虚拟主机
- 安装DNS服务
[root@localhost nginx]# yum install bind -y
[root@localhost nginx]# vim /etc/named.conf
12 options {
13 listen-on port 53 { any; }; //修改为any
14 listen-on-v6 port 53 { ::1; };
15 directory "/var/named";
16 dump-file "/var/named/data/cache_dump.db";
17 statistics-file "/var/named/data/named_stats.txt";
18 memstatistics-file "/var/named/data/named_mem_stats.txt";
19 recursing-file "/var/named/data/named.recursing";
20 secroots-file "/var/named/data/named.secroots";
21 allow-query { any; }; //修改为any
[root@localhost nginx]# vim /etc/named.rfc1912.zones
25 zone "kgc.com" IN { //修改域名为kgc.com
26 type master;
27 file "kgc.com.zone"; //修改为kgc.com.zone
28 allow-update { none; };
29 };
30
31 zone "yun.com" IN { //复制模板，将域名更改为yun.com
32 type master;
33 file "yun.com.zone";
34 allow-update { none; };
35 };
[root@localhost nginx]# cd /var/named/
[root@localhost named]# cp -p named.localhost kgc.com.zone
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1
//AAAA（IPv6）删除
www IN A 192.168.179.180 //www解析为本机IP地址
[root@localhost named]# cp -p kgc.com.zone yun.com.zone
- 测试DNS服务
[root@localhost named]# systemctl start named
- 手工编译安装Nginx服务
//解压缩包
tar zxvf nginx-1.12.2.tar.gz -C /opt
//创建用户
useradd -M -s /sbin/nologin nginx
//安装环境依赖包
yum install gcc gcc-c++ pcre pcre-devel zlib-devel -y
//配置
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module
//安装
make && make install
//创建软连接，方便命令文件管理
ln -s /usr/local/nginx/sbin/* /usr/local/sbin
便于服务管理
vim /etc/init.d/nginx
#!/bin/bash
# chkconfig: - 99 20
# description: Nginx Service Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
$PROG;;
stop)
kill -s QUIT $(cat $PIDF);;
restart)
$0 stop
$0 start;;
reload)
kill -s HUP $(cat $PIDF);;
*)
exit 1
esac
exit 0
//添加执行权限
chmod +x /etc/init.d/nginx
//添加为系统服务
chkconfig --add nginx
- 基于域名构建虚拟主机
[root@localhost named]# vim /usr/local/nginx/conf/nginx.conf
//在原有的server更改
server {
36 listen 80;
37 server_name www.kgc.com;
38 location / {
39 root /var/www/kgc;
40 index index.html index.htm;
41 }
42 error_page 500 502 503 504 /50x.html;
43 location = /50x.html {
44 root html;
45 }
46 }
47 //复制域名kgc.com，修改域名为yun.com
48 server {
49 listen 80;
50 server_name www.yun.com;
51 location / {
52 root /var/www/yun;
53 index index.html index.htm;
54 }
55 error_page 500 502 503 504 /50x.html;
56 location = /50x.html {
57 root html;
58 }
59 }- 创建主页面文件
mkdir -p /var/www/kgc
mkdir -p /var/www/yun
echo "this is kgc web" >/var/www/kgc/index.html
echo "this is yun web" >/var/www/yun/index.html
//重启服务访问
三.基于端口的虚拟主机
- 基于端口的虚拟主机和基于域名配置基本一样，区别在于，Nginx的主配置文件中，修改server{}参数
[root@localhost www]# vim /usr/local/nginx/conf/nginx.conf
server {
listen 192.168.179.180:80; //主机监听地址要改为本机IP地址
server_name www.kgc.com;
location / {
root /var/www/kgc;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
server {
listen 192.168.179.180:8080;
server_name www.kgc.com;
location / {
root /var/www/kgc80;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}- 创建站点目录kgc80，
[root@localhost www]# mkdir -p /var/www/kgc80
[root@localhost www]# echo "this is kgc8080 web" >/var/www/kgc80/index.html- 重启服务，重新访问
[root@localhost www]# service nginx stop
[root@localhost www]# service nginx start
[root@localhost www]# netstat -ntap | grep nginx
tcp 0 0 192.168.179.180:8080 0.0.0.0:* LISTEN 43871/nginx: master
tcp 0 0 192.168.179.180:80 0.0.0.0:* LISTEN 43871/nginx: master
[root@localhost www]#
