jar自动化启停备份脚本

jar包启停

建议以下脚本和部署的jar(服务)放在同一目录下。

start.sh

jar启动脚本，默认会查找当前目录下jar进行启动，也可传入对应需启动jar路径。

#! /bin/bash

#进入脚本所在目录
cd `dirname $0`

#不传需要启动的jar，默认在当前目录下查找
server_name=$1
if [ -z "$server_name" ];then
  server_name=$(find . -name '*.jar'|head -1)
  if [[ $server_name =~ "/" ]];then
    server_name=${server_name##*/}
  fi
fi

#如果要启动的jar非普通文件，直接返回错误
if [ ! -f "$server_name" ];then
  echo "not find server ->  ${server_name}"
  exit 1
fi
echo "start ${server_name}"

#export JAVA_HOME=jre地址
#export PATH=$PATH:${JAVA_HOME}/bin
#执行
nohup java -XX:+UseG1GC -Xmx512m -XX:MaxGCPauseMillis=200 -XX:GCPauseIntervalMillis=300 -jar $server_name --spring.profiles.active=prod > /dev/null 2>&1 &

exit 0

不能正常启动大部分原因可能是java环境变量问题。

stop.sh

jar停止脚本，默认优雅地停止。可设置默认超时秒数（默认10秒），如果超过超时秒数仍未成功停止，则直接kill进程。

#! /bin/bash

#进入脚本所在目录
cd `dirname $0`

server_name=$1
#默认优雅停止，超过指定秒数直接kill
timeout_seconds=$2

#不传需要停止的服务名，默认在当前目录下查找
if [ -z "$server_name" ];then
  server_name=$(find . -name '*.jar'|head -1)
  if [[ $server_name =~ "/" ]];then
    server_name=${server_name##*/}
  fi
fi

#如果要停止的jar非普通文件，直接返回成功
if [ ! -f "$server_name" ];then
  echo "not find server ->  ${server_name}"
  exit 0
fi

#默认超时时间10秒
default_seconds=10
if [ -z "$timeout_seconds" ];then
  timeout_seconds=$default_seconds
fi

expr $timeout_seconds + 1 > /dev/null 2>&1
timeout_seconds=$([ $? -ne 0 ] && echo $default_seconds || echo ${timeout_seconds})

server_pid=`ps -ef|grep java|grep $server_name|awk '{print $2}'`
echo "kill ${server_pid} -> ${server_name}"

if [ -n "$server_pid" ]; then
  kill ${server_pid}
  tmp_pid=${server_pid}
  while [ -n "$tmp_pid" ]
  do
    sleep 1
    tmp_pid=`ps -ef|grep java|grep $server_name|awk '{print $2}'`
    timeout_seconds=`expr $timeout_seconds - 1`
    if [ $timeout_seconds -lt 0 ] && [ -n "$tmp_pid" ];then
      echo "kill -9 ${server_pid} -> ${server_name}"
      kill -9 ${tmp_pid}
      break;
    fi
  done
fi

exit 0

$1：服务名称，不写会默认查找
$2：停止超时时间，默认10。超过默认时间走kill -9

bak.sh

备份脚本，默认备份当前目录下查找到的一个jar，也可传入jar目录。

#! /bin/bash

#进入脚本所在目录
cd `dirname $0`

day_ymd=$(date +'%Y%m%d')

server_name=$1
if [ -z "$server_name" ];then
  server_name=$(find . -name '*.jar'|head -1)
  if [[ $server_name =~ "/" ]];then
    server_name=${server_name##*/}
  fi
fi

if [ ! -f "$server_name" ];then
  echo "not find server ->  ${server_name}"
  exit 0
fi

suffix_numb=0
for line in $(find ./ -name "${server_name}.${day_ymd}*")
do
  tmp_numb=${line##*-}
  if [ -n "$tmp_numb" ]; then
    expr $tmp_numb + 1 > /dev/null 2>&1
    tmp_numb=$([ $? -ne 0 ] && echo 0 || echo ${tmp_numb})
    if [ $suffix_numb -lt $tmp_numb ]; then
      suffix_numb=$tmp_numb
    fi
  fi
done
suffix_numb=$(expr ${suffix_numb} + 1)

mv ${server_name} ${server_name}.${day_ymd}-${suffix_numb}

exit 0

默认的备份格式是：${server_name}.yyyyMMdd-数字

remote_ci.sh

远程部署脚本，功能：停止远程服务->备份远程服务->传送当前jar到远程服务器->启动远程服务

#! /bin/bash 

#进入脚本所在目录
server_path=$(cd `dirname $0`; pwd)
cd $server_path

remote_address=root@ip
passwd=服务器密码
#远程jar所在目录，这里默认为$server_path
remote_server_path=$server_path

timeout=20
passwderror=0


#需要scp传送的jar名称
server_name=$1
if [ -z "$server_name" ];then
  server_name=$(find . -name '*.jar'|head -1)
  if [[ $server_name =~ "/" ]];then
    server_name=${server_name##*/}
  fi
fi

if [ ! -f "$server_name" ];then
  echo "not find server ->  ${server_name}"
  exit 0
fi

#停止远程服务，并备份
/usr/bin/expect <<EOF

spawn ssh $remote_address "cd ${remote_server_path} ; sh ./stop.sh; sh ./bak.sh"

expect {
  "*assword:*" {
    if { $passwderror == 1 } {
      puts "passwd is error"
      exit 2
    }
    set timeout 1000
    set passwderror 1
    send "$passwd\r"
    exp_continue
  }
  "*es/no)?*" {
    send "yes\r"
    exp_continue
  }
  timeout {
    puts "connect is timeout"
    exit 3
  }
}
EOF

#把新构建的jar传到远程服务器

      exit 2
    }
    set timeout 1000
    set passwderror 1
    send "$passwd\r"
    exp_continue
  }
  "*es/no)?*" {
    send "yes\r"
    exp_continue

  timeout {
    puts "connect is timeout"
    exit 3

    exp_continue

  timeout {
    puts "connect is timeout"
    exit 3

}
EOF

exit 0

expect需要提前安装，yum install expect
