分享：服务器部署java的环境和应用

初始化 ECS

购买 ECS

• 阿里云 ECS 官网 https://www.aliyun.com/minisite/goods?userCode=ueyxv2qf

• 数据库/redis 等也安装在云上 镜像选择centos7

初始化 CentOS7

curl -O http://pigx.vip/os7init.sh

sh os7init.sh pig4cloud


安装 JDK

yum install -y java

java -version


安装 Mysql 8

https://dev.mysql.com/downloads/

rpm -ivh  xx.rpm

yum install -y mysql mysql-server

vi /etc/my.cnf

lower_case_table_names=1

systemctl restart mysqld

grep password /var/log/mysqld.log

set global validate_password.check_user_name=0;
set global validate_password.policy=0;
set global validate_password.length=1;

alter user 'root'@'localhost' identified by 'root';

use mysql;

update user set host = '%' where user = 'root';

FLUSH PRIVILEGES;


安装 Redis

yum install redis

systemctl restart redis


安装 NGINX

• https://nginx.org/en/linux_packages.html

vim /etc/yum.repos.d/nginx.repo

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

yum install -y yum-utils
yum-config-manager --enable nginx-mainline
yum install -y nginx


配置 hosts

vim /etc/hosts

127.0.0.1   pig-mysql
127.0.0.1   pig-redis
127.0.0.1   pig-gateway
127.0.0.1   pig-register
127.0.0.1   pig-sentinel
127.0.0.1   pig-job

source /etc/hosts


部署 pig

准备源码包

• pig 服务端 编译 jar

mvn clean install


• pig-ui 前端 编译 dist

npm run build


初始化数据库

• pig db目录

source pig.sql
source pig_codegen.sql
source pig_config.sql
source pig_job.sql


启动服务端

nohup java -Dfile.encoding=utf-8 -jar pig-register.jar > /dev/null 2>&1 &

nohup java -Dfile.encoding=utf-8 -jar pig-monitor.jar > /dev/null 2>&1 &
nohup java -Dfile.encoding=utf-8 -jar pig-sentinel-dashboard.jar > /dev/null 2>&1 &
nohup java -Dfile.encoding=utf-8 -jar pig-xxl-job-admin.jar > /dev/null 2>&1 &

nohup java -Dfile.encoding=utf-8 -jar pig-gateway.jar > /dev/null 2>&1 &
nohup java -Dfile.encoding=utf-8 -jar pig-auth.jar > /dev/null 2>&1 &
nohup java -Dfile.encoding=utf-8 -jar pig-upms-biz.jar > /dev/null 2>&1 &


部署前端

mkdir -p /data/pig-ui && cp -r dist/* /data/pig-ui

cd /etc/nginx/conf.d && rm -f default.conf

vim pigx.conf

server {
   listen 80;
   server_name localhost;
   
   # 打包好的dist目录文件，放置到这个目录下
   root /data/pig-ui;
   
   # 注意维护新增微服务，gateway 路由前缀
   location ~* ^/(code|auth|admin|gen) {
      proxy_pass http://127.0.0.1:9999;
      #proxy_set_header Host $http_host;
      proxy_connect_timeout 15s;
      proxy_send_timeout 15s;
      proxy_read_timeout 15s;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto http;
   }
}

nginx


ECS 安全组

• 注意配置安全组，服务相关的端口对外暴露

• 80/443

• 9999 网关 （如需访问swagger 需要）

• 5001 监控 （如需访问monitor 需要）

• 5020 监控 （如需访问monitor 需要）
