先安装nginx

然后配置nginx.conf文件，这里我总结了三种比较简单的方法
第一种：一个server，配置多个location

server {
listen 80 ;
server_name localhost;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location /a/ {

proxy_pass http://localhost:8080/;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}
location /b/ {

proxy_pass http://localhost:8070/;
proxy_redirect off;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
error_page 404 /404.html;
location = /40x.html {
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}

这里的a和b是你的项目名，也就是你的context-path

第二种:
多个server，同一端口，根据域名server_name来匹配

server {
listen 80 ;
server_name www.bbb.com;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location /{

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
server {
listen 80 ;
server_name www.aaa.com;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location /{

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}

第三种，多个server，根据监听不同的端口来匹配

server {
listen 80 ;
server_name www.bbb.com;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location /{

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
server {
listen 81 ;
server_name www.aaa.com;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

location /{

error_page 500 502 503 504 /50x.html;
location = /50x.html {
}

由于我的项目是jar包发布，所以最后我用了一个shell脚本去批量启动jar包。

#! /bin/sh
# 端口号
PORTS=(8080 8070)
# 系统模块
MODULES=(bterminal wechat)
# 系统模块名称
MODULE_NAMES=(b端程序微信小程序)
# jar包数组
JARS=(printshopweb-0.0.1-SNAPSHOT.jar wechatprinting-0.0.1-SNAPSHOT.jar)
# jar包路径
JAR_PATH='/root'
# 日志路径
LOG_PATH='/root'

while [ -z "$PID" ]
do
if (($count == 30));then
echo "$MODULE---$MODULE_NAME:$(expr $count \* 10)秒内未启动,请检查!"
break

count=$(($count+1))

}
