# frontend-deployment

The front-end has three deployment modes: automated deployment, manual deployment and compiled source deployment.



## Preparations

#### Download the installation package

Please download the latest version of the installation package, download address： [gitee](https://gitee.com/easyscheduler/EasyScheduler/attach_files/)

After downloading escheduler-ui-x.x.x.tar.gz，decompress`tar -zxvf escheduler-ui-x.x.x.tar.gz ./`and enter the`escheduler-ui`directory




## Deployment

Automated deployment is recommended for either of the following two ways

### Automated Deployment

Edit the installation file`vi install-escheduler-ui.sh` in the` escheduler-ui` directory

Change the front-end access port and the back-end proxy interface address

```
# Configure the front-end access port
esc_proxy="8888"

# Configure proxy back-end interface
esc_proxy_port="http://192.168.xx.xx:12345"
```

>Front-end automatic deployment based on Linux system `yum` operation, before deployment, please install and update`yum`

under this directory, execute`./install-escheduler-ui.sh` 


### Manual Deployment

Install epel source `yum install epel-release -y`

Install Nginx `yum install nginx -y`

    location = /50x.html {
        root   /usr/share/nginx/html;
    }
