本地客控服务器安装文档

## 系统安装

建议使用较为成熟稳定的系统，常用centos7，可最小化安装；

## 基础环境安装

### jdk1.8安装配置

1. 新建文件夹

```shell
sudo mkdir -p /usr/java
```

2. 上传jdk文件jdk-8u221-linux-x64.tar.gz，并解压文件生成jdk1.8.0_221 文件夹

```shell
tar -zxvf jdk-8u221-linux-x64.tar.gz
```

3. 配置系统环境变量

```sh
vim  /etc/profile
```

末尾添加

```shell
export JAVA_HOME=/usr/java/jdk1.8.0_221
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export LD_LIBRARY_PATH=/usr/local/yellow/library
```

生效

```shell
source /etc/profile	
```

### mysql数据库

安装8.X版本mysql数据库

参考博客：https://blog.csdn.net/li_c_yang/article/details/109048002

### redis数据库

参考博客：https://blog.csdn.net/li_c_yang/article/details/116422404

### nginx安装

安装过程很简单，网上查询

添加自启动文件

```shell
vim  /usr/lib/systemd/system/nginx.service
```

内容

```sh
[Unit]
Description=nginx - web server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
ExecQuit=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true

[Install]
WantedBy=multi-user.target
```

生效

```shell
systemctl daemon-reload
```

配置nginx开机自启

```shell
systemctl enable nginx
```

常用命令

```shell
systemctl start nginx

systemctl stop nginx

systemctl status nginx
```

## 客控系统安装

### 后台部署

#### 1.新建用户

```shell
useradd moorgen
```

设置用户密码

```shell
passwd moorgen
```

#### 2.切换到新用户进行操作

使用新建的用户远程登录默认进入  /home/moorgen目录

新建客控系统文件夹

```
mkdir -p hotel
```

上传jar运行文件和运行脚本start_app，并给运行脚本添加权限：chmod  +x start_app

运行jar包

```shell
./start_app start
#查看日志
./start_app log
#停止进程
./start_app stop
```

#### 3.添加自启动文件

```bash
[Unit]
Description=Hotel Java Application Service
After=network.target mysqld.service redis.service
Requires=mysqld.service redis.service

[Service]
Type=forking
User=moorgen
Group=moorgen
WorkingDirectory=/home/moorgen/hotel
ExecStart=/home/moorgen/hotel/start_app start
ExecStop=/home/moorgen/hotel/start_app stop
ExecReload=/home/moorgen/hotel/start_app restart
Restart=no

# 可选：设置超时时间（防止长时间等待）
TimeoutStartSec=60
TimeoutStopSec=30

[Install]
WantedBy=multi-user.target

```

生效

```shell
systemctl daemon-reload
```

配置nginx开机自启

```shell
systemctl enable hotel.service
```

常用命令

```shell
systemctl start hotel.service

systemctl stop hotel.service

systemctl status hotel.service
```

### 前端部署

#### 1.上传前端文件dist.zip到/home/moorgen/hotel，解压生成dist

#### 2.配置nginx的配置文件 vim /usr/local/nginx/conf/nginx.conf

```shell
    server {
        listen       80;
        server_name  localhost;

root /home/moorgen/hotel/dist;
        location / {
             try_files $uri $uri/ @router;
             index  index.html;
        }
        location @router{
             rewrite ^.*$ /index.html last;
        }
        
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
```

注意：修改nginx.conf 配置  **user  root;**

重新加载配置文件

```shell
/usr/local/nginx/sbin/nginx -s reload
```

启动文件

```shell
#!/bin/sh  
#该脚本为Linux下启动java程序的通用脚本。即可以作为开机自启动service脚本被调
APP_PATH=$(dirname $(readlink -f $0))
APP_NAME=hotel-app
JAR_NAME=hotel-0.0.1-SNAPSHOT.jar
LOG_NAME=logs/debug.log
JAVA_OPT="-Dspring.profiles.active=pro -Xms2G -Xmx2G -Xss256k"
