【脚本】Go语言快速构建部署脚本（启动，构建，重启，停止）

1. 前言

参考Springboot的启动脚本：

写了这个脚本，尝试写一下shell脚本

程序员正是为了懒而懒的....

脚本基础功能：

build：构建 start：启动 status：查询状态 restart：重启（会重新构建，比如代码更新了...）

最主要，在博客里面备份下脚本：

#!/bin/bash
RED="\033[31m"
GREEN="\033[32m"
YELLOW="\033[33m"
END="\033[0m"

echo $1 $2

if [ "$1" = "" ];then
  echo -e "\033[0;31m 请输入操作名 \033[0m"
  exit 1
fi


if [ ! -f "go.mod" ];
then
  echo -e "go.mod文件不存在，请在项目目录运行..."
  exit 1
fi



GoName=`head -n 1 go.mod| awk '{print $2}'`

function stop()
{
    print_color_string 'red' "stopping..."
    boot_id=`ps -ef | grep $GoName |grep -v grep|awk '{print $2}'`
    count=`ps -ef |grep $GoName |grep -v grep|wc -l`
    if [ $count != 0 ];then
        kill $boot_id
        count=`ps -ef |grep $GoName |grep -v grep|wc -l`
    fi
    print_color_string 'green' "stopped!"

}


function build()
{
    if [ -f $GoName ]; then
        print_color_string 'red' "deleting old execute file..."
        rm -rf $GoName
    fi
    print_color_string 'green' "building...."

    go build
    if [ $? != 0 ] ;then
       print_color_string 'red' "fail to build"
    else
       print_color_string 'green' "success to build"
    fi
}


function start()
{
    print_color_string 'green' "starting...."
    if [ ! -f $GoName ]; then
        print_color_string 'yellow' "no execute file, building...."
        build
    fi

    nohup ./$GoName 1>/dev/null 2>&1 &
    print_color_string 'green' "started!"
}


function status()
{
    count=`ps -ef |grep $GoName |grep -v grep|wc -l`
    if [ $count != 0 ];then
        print_color_string 'green' "$GoName is running..."
    else
        print_color_string 'red' "$GoName is not running..."
    fi
}

function restart()
{
    build
    stop
    sleep 1
    start
}

print_color_string(){
    color=$1
    string=$2
    case $color in
        red)
                echo -e "$RED $string $END"
                ;;
        green)
                echo -e "$GREEN $string $END"
                ;;
        yellow)
                echo -e "$YELLOW $string $END"
                ;;
        *)
                echo $string
                ;;
    esac
}
