Nginx 配置文件
vim /usr/local/nginx/conf/nginx.conf
66 listen 8080 default_server;
lnmp nginx restart
测试 192.168.103.254:8080
- vim /usr/local/nginx/conf/nginx.conf
70 root /www;
mkdir /www
vim /www/index.html
hello www!
lnmp nginx restart
测试 192.168.103.254
vim /usr/local/nginx/conf/nginx.conf
72 error_page 404 /404.html;
cd /home/wwwroot/default
vim 404.html
hi 404!
lnmp nginx restart
测试 192.168.104.254/aaaaa.html
状态监控
测试 192.168.104.254/nginx_status
检查配置文件是否有语法错误
/usr/local/nginx/sbin/nginx -t
平滑重启
pkill -HUP nginx
实验1：虚拟主机
1）域名解析 文件解析
192.168.103.254 www.sina.com
192.168.103.254 www.sohu.com
2）网站目录规划
mkdir /home/wwwroot/sina/
mkdir /home/wwwroot/sohu/
vim /home/wwwroot/sina/index.html
hi sina!
vim /home/wwwroot/sohu/index.html
hello sohu!
3)修改配置文件
vim /usr/local/nginx/config/nginx.conf
66 listen 80;
4)建立虚拟主机文件
vim /usr/local/nginx/conf/vhost/v.conf
1 server {
2 listen 80;
3 server_name = www.sina.com;
4 index index.html index.htm index.php;
5 root /home/wwwroot/sina;
6
7 include enable-php.conf;
8 }
9 server {
10 listen 80;
11 server_name = www.sohu.com;
12 index index.html index.htm index.php;
13 root /home/wwwroot/sohu;
14
15 include enable-php.conf;
16 }
- 重启服务 测试
pkill -HUP nginx
实验2： 列表页显示
vim /usr/local/nginx/conf/nginx.conf
64 server
65 {
66 listen 80;
67 # default_server;
68 #listen [::]:80 default_server ipv6only=on;
69 server_name www.lnmp.org;
70 index index.html index.htm index.php;
71 root /home/wwwroot/default;
72 autoindex on;
pkill -HUP nginx
cd /home/wwwroot/default
mv index.html a.html
测试 192.168.103.254 列表
实验3：状态监控
vim /usr/local/nginx/conf/vhost/v.conf
8 location /nginx_status{
9 stub_status on;
10 access_log off;
11 }
pkill -HUP nginx
实验4：rewrite 重写/重定向
1)修改配置文件
vim /usr/local/nginx/conf/vhost/v.conf
1 server {
2 listen 80;
3 server_name = www.sina.com;
4 index index.html index.htm index.php;
5 root /home/wwwroot/sina;
6 autoindex on;
7 include enable-php.conf;
8 if ($http_host = www.sina.com) {
9 rewrite (.*) http://www.sohu.com permanent;
10 }
2）重启服务 测试
pkill -HUP nginx
测试 www.sina.com ->www.sohu.com
网页文件跳转
1）vim /usr/local/nginx/conf/vhost/v.conf
1 server {
2 listen 80;
3 server_name = www.sina.com;
4 index index.html index.htm index.php;
5 root /home/wwwroot/sina;
6 autoindex on;
7 include enable-php.conf;
8 rewrite index(\d+).html /index.php?id=$1 last;
- 建立index.php
vim /home/wwwroot/sina/index.php
<?php echo “hello” ?>
3)重启服务 测试
pkill -HUP nginx
实验5：代理负载均衡（反向代理）
实验准备： S Nginx 192.168.103.254 分发
S1 Nginx 192.168.103.140 解析
S2 Nginx 192.168.103.199 解析
1）修改配置文件 S 192.168.103.254
vim /usr/local/nginx/conf/nginx.conf
65 upstream myweb1 {
66 server 192.168.103.140:80;
67 server 192.168.103.199:80;
68 }
69 server {
70 listen 80;
71 server_name www.sohu.com;
72 location / {
73 proxy_pass http://myweb1;
74 proxy_next_upstream http_500 http_502 http_503 error timeout invalid_header;
75 proxy_set_header Host $host;
76 proxy_set_header X-Forwarded-For $remote_addr;
77 }
78 }
- 修改S1 192.168.103.140 文件
关闭虚拟主机
cd /home/wwwroot/default/
vim index.html
S11111111111111
测试 192.168.103.140 S11111111111111
- 修改S1 192.168.103.199 文件
关闭虚拟主机
cd /home/wwwroot/default/
vim index.html
S22222222222222222
测试 192.168.103.199 S222222222222222222
4）重启S 服务器 测试
pkill -HUP nginx
测试 www.sohu.com
