CentOS中nginx负载均衡和反向代理的搭建

 1:配置虚拟主机:

1、nginx支持的三种虚拟主机的配置:
基于ip的虚拟主机
基于域名的虚拟主机
基于端口的虚拟主机

2、nginx配置文件的结构: 每个service就是一个虚拟主机
......
events{
......
}

http{
.......
server{
......
}

server{
......
}
}

3、基于ip的虚拟主机配置:
修改配置文件: vim /usr/local/nginx/nginx-1.8.0/conf/nginx.conf
server{
listen 80;
server_name 192.168.31.88;

location / {
root html;
index index.html index.htm;
}
}

4、基于域名的虚拟主机配置:
修改配置文件:vim /usr/local/nginx/nginx-1.8.0/conf/nginx.conf
server{
listen 80;
server_name www.nginxdns1.com;

location / {
root html_dns1;
index index.html index.htm;
}
}

server{
listen 80;
server_name www.nginxdns2.com;

location / {
root html_dns2;
index index.html index.htm;
}
}

5、基于端口的虚拟主机配置:
修改配置文件:vim /usr/local/nginx/nginx-1.8.0/conf/nginx.conf

监听端口:netstat -an | grep 80
server{
listen 88;
server_name 192.168.31.88;

location / {
root html_port1;
index index.html index.htm;
}
}

server{
listen 89;
server_name 192.168.31.88;

location / {
root html_port2;
index index.html index.htm;
}
}

2、nginx 反向代理:
修改hosts:# nginx反向代理环境测试
192.168.31.88 www.nginxproxy1.com
192.168.31.88 www.nginxproxy2.com

开启不同虚拟机中的两台tomcat:192.168.31.88:8080 和 192.168.31.89:8081
修改配置文件:

#代理tomcat1服务器
upstream tomcat_server1{
server 192.168.31.89:8081;
}

#代理tomcat2服务器
upstream tomcat_server2{
server 192.168.31.88:8080;
}

#配置虚拟主机:
server{
listen 80;
server_name www.nginxproxy1.com;

location / {
#root html_port1;

proxy_pass http://tomcat_server1;
index index.html index.htm;
}
}

server{
listen 80;
server_name www.nginxproxy2.com;

location / {
#root html_port2;
proxy_pass http://tomcat_server2;
index index.html index.htm;
}
}

3、nginx 负载均衡:
修改hosts :# nginx负载均衡环境测试
192.168.31.88 www.nginxbalance.com

开启不同虚拟机中的两台tomcat:192.168.31.88:8080 和 192.168.31.89:8081
修改配置文件:

#代理tomcat2服务器
upstream tomcat_server_pool{
server 192.168.31.88:8080 weight=1;
server 192.168.31.89:8081 weight=1;
}

#配置虚拟主机:
server{
listen 80;
server_name www.nginxbalance.com;

location / {
#root html_port1;

proxy_pass http://tomcat_server_pool;
index index.html index.htm;
}
}

hosts文件配置:
1:nginx基于域名环境测试
192.168.31.88 www.nginxdns1.com
192.168.31.88 www.nginxdns2.com

2:nginx反向代理环境测试
192.168.31.88 www.nginxproxy1.com
192.168.31.88 www.nginxproxy2.com

3:nginx负载均衡环境测试
192.168.31.88 www.nginxbalance.com
