1.http服务器
2.虚拟主机
3.反向代理,负载均衡
安装nginx
配置虚拟主机:
/usr/local/nginx/conf/nginx.conf
一个server就是一个虚拟主机
1.通过端口访问
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
}
server {
listen 81;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
}
2.共用80端口,通过域名访问
server {
listen 80;
server_name www.jd.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
}
server {
listen 80;
server_name www.taobao.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
}
反向代理：
启动两个tomcat:
upstream tomcat1 {
server 192.168.25.148:8080;
}
server {
listen 80;
server_name www.sina.com.cn;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://tomcat1;
index index.html index.htm;
}
}
upstream tomcat2 {
server 192.168.25.148:8081;
}
server {
listen 80;
server_name www.sohu.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://tomcat2;
index index.html index.htm;
}
}
负载均衡:
再启动一个tomcat,修改端口为8082,
访问www.sohu.com会轮询访问 weight=2的请求次数越多
upstream tomcat2 {
server 192.168.25.148:8081;
server 192.168.25.148:8082 weight=2;
}
server {
listen 80;
server_name www.sohu.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
proxy_pass http://tomcat2;
index index.html index.htm;
}
}
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
|
location / {
root html;
index index.html index.htm;
}
}
