centos 部署整套应用

基础环境搭建

① 购买 ECS

:::warning

• 点击 阿里云 ECS 官网 购买有优惠
• 最低 8G 内存，数据库/redis 等也安装在云上 镜像选择centos7 :::

② 初始化 CentOS7

curl -O https://pigx.vip/os7init.sh 
sh os7init.sh pig4cloud

③ 安装 JDK

yum install -y java
java -version

④ 安装 Mysql 8

:::success 点击下载 Mysql rpm 安装包 mysql80-community-release-el7-7.noarch.rpm.zip :::

rpm -ivh mysql80-community-release-el7-7.noarch.rpm
yum install -y mysql mysql-server
# 修改配置文件
vim /etc/my.cnf
lower_case_table_names=1
# 重启mysql
systemctl restart mysqld
# 查看默认密码
grep password /var/log/mysqld.log
# mysql client 链接 mysql
alter user 'root'@'localhost' identified by 'ZxcRoot123!@#';
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';
# 修改为允许远程访问
use mysql;
update user set host = '%' where user = 'root';
FLUSH PRIVILEGES;

⑤ 安装 Redis

yum install redis
systemctl restart redis

⑥ 安装 NGINX

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

⑦ 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

部署应用代码

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

mysql -uroot -proot
>
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;
    gzip on;
    gzip_static on;     # 需要http_gzip_static_module 模块
    gzip_min_length 1k;
    gzip_comp_level 4;
    gzip_proxied any;
    gzip_types text/plain text/xml text/css;
    gzip_vary on;
    gzip_http_version   1.0; #兼容多层nginx 反代
    gzip_disable "MSIE [1-6]\.(?!.*SV1)";
    # 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 $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto http;
    }
    # 避免端点安全问题
    if ($request_uri ~ "/actuator"){
        return 403;
    }
}
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 (生产模式只需要开启此关口)

• 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）
