Linux shell脚本

本文主要是介绍Linux shell脚本，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1.jenkins部署脚本

# !/bin/sh
#防止shell里使用nohup不能后台运行直接挂掉
BUILD_ID=DONTKILLME
jarpath="/home/wowed/wowed-account"
#切换到jar包路径
 cd ${jarpath}
#获取当前服务的进程是否存在,注意jenkins和centos写法不一样，防止jenkins被杀死
#要加上grep -v grep这个过滤操作
pid=`ps -ef|grep wowed-account-service|grep -v grep|awk '{print $2}'`
 #如果存在的话
if [[ -n "$pid" ]]
    then
    echo ' 当前服务已经启动，现在进行重启操作... '
    kill -9 $pid
    killsuccess=$?
    sleep 3s
    if  [[ ${killsuccess} == '0'  ]]
       then
          echo "服务关闭成功"
          cd ${jarpath}
          nohup java -jar wowed-account-service-1.0.jar >/dev/null 2>&1 &
      else
          echo "服务关闭失败"
    fi
else
    echo '服务进程不存在直接启动'
    cd ${jarpath}
    nohup java -jar wowed-account-service-1.0.jar >/dev/null 2>&1 &
fi
cp /dev/null nohup.out
echo "部署完成..."

2.jenkins部署docker脚本

SERVER_NAME=springbootadmin
#容器id 
 CID=$(docker ps | grep "$SERVER_NAME" |grep -v grep| awk '{print $1}') 
 #镜像id 
 IID=$(docker images | grep "$SERVER_NAME" |grep -v grep| awk '{print $3}')   
# 构建docker镜像         
 if [ -n "$IID" ]; then                 
 echo "存在$SERVER_NAME镜像，IID=$IID"                 
  docker stop $SERVER_NAME
   # 停止运行中的容器                 
  docker rm $SERVER_NAME    
 ##删除原来的容器         
   docker rmi $IID   
## 删除原来的镜像           
else                 
 echo "不存在$SERVER_NAME镜像，开始构建镜像"                               
 fi  

cd /home/wowed/springbootadminnew
docker build -t $SERVER_NAME . 
docker run -d --name $SERVER_NAME -p 10000:10000 $SERVER_NAME

3.jenkins部署jar 脚本

#!/bin/sh
BUILD_ID=DONTKILLME
source ~/.bash_profile
export PATH="/usr/java/jdk1.8.0_131:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:."

APP_NAME=wowed-account-service-1.0.jar
APP_FOLDER=/home/wowed/wowed-account

#Serivce方式启动的命令
SERVICE_NAME=nl_wowed_account

APP="$APP_FOLDER/$APP_NAME"

#初始化配置文件
APP_CONFIG=${APP_NAME%%.jar*}.conf
APP_CONFIG_CONTENT='JAVA_HOME=/usr/java/jdk1.8.0_131\n
JAVA_OPTS="-server -Xmx512M -Xms512M -Dfile.encoding=UTF-8"\n
RUN_ARGS="--spring.profiles.active=dev"\n
PID_FOLDER="/home/wowed/wowed-account/pids"\n
LOG_FOLDER=/home/wowed/logs'

if [[ -f "$APP_FOLDER/$APP_CONFIG" ]]; then
 echo "App config file already existed."
else
 echo "App config file does not exist, I will create it..."
 echo -e  $APP_CONFIG_CONTENT > $APP_FOLDER/$APP_CONFIG
 echo "Create app config file completion. [ $APP_FOLDER/$APP_CONFIG ]"

fi

echo "Stop and start $APP"
#判断/etc/init.d/下是否已经存在软链接

count=`ps -ef|grep java|grep $APP_NAME|grep -v grep |wc -l`
if [ $count != 0 ];then
 boot_id=`ps -ef|grep java|grep $APP_NAME|grep -v grep | awk '{print $2}'`
 echo "kill $boot_id"
 kill -9 $boot_id
fi

mkdir -p ${APP_FOLDER}/pids
sudo ln -s $APP /etc/init.d/$SERVICE_NAME
chmod +x $APP
service nl_wowed_account start
echo "service $SERVICE_NAME start."


==============千万要注意：这种方式启动不能勾选Exec in pty ? 这个选项================

4.jenkins单服务脚本

#!/bin/sh
source ~/.bash_profile

APP_NAME=wowed-account-service-1.0.jar
APP_FOLDER=/home/wowed/wowed-account

#Serivce方式启动的命令
SERVICE_NAME=nl_wowed_account

APP="$APP_FOLDER/$APP_NAME"

#初始化配置文件
APP_CONFIG=${APP_NAME%%.jar*}.conf
APP_CONFIG_CONTENT='JAVA_HOME=/usr/java/jdk1.8.0_131\n
JAVA_OPTS="-server -Xmx512M -Xms512M -Dfile.encoding=UTF-8"\n
RUN_ARGS="--spring.profiles.active=dev"\n
PID_FOLDER="/home/wowed/wowed-account/pids"\n
LOG_FOLDER=/home/wowed/logs'

if [[ -f "$APP_FOLDER/$APP_CONFIG" ]]; then
 echo "App config file already existed."
else
 echo "App config file does not exist, I will create it..."
 echo -e  $APP_CONFIG_CONTENT > $APP_FOLDER/$APP_CONFIG
 echo "Create app config file completion. [ $APP_FOLDER/$APP_CONFIG ]"
fi

echo "Stop and start $APP"
#判断/etc/init.d/下是否已经存在软链接

count=`ps -ef|grep java|grep $APP_NAME|grep -v grep |wc -l`
if [ $count != 0 ];then
 boot_id=`ps -ef|grep java|grep $APP_NAME|grep -v grep | awk '{print $2}'`
 echo "kill $boot_id"
 kill -9 $boot_id
fi


mkdir -p ${APP_FOLDER}/pids
chmod +x $APP

sudo ln -s $APP /etc/init.d/$SERVICE_NAME
service $SERVICE_NAME start
echo "service $SERVICE_NAME start."

5.mysql备份脚本

#mysql定时备份脚本,以小时为单位进行备份，只需要修改mysqlip以及在centos里面配置一个cron表达式即可
#=====================定时任务============================
crontab -e 就可以打开一个文件进行编辑
#每整点执行一次:
0 */1 * * * /home/wowed/mysqlbak.sh
#===========================================================


#!/bin/bash
mysqlip=192.168.25.111
cd ~
path="$(pwd)/mysqlbak/$(date +%Y%m%d%H)"
echo ${path}
if [ -e  $path ]
then
  echo "mysql备份目录存在,不创建目录"
else
  echo "mysql备份目录不存在,创建目录"
  mkdir -p ${path}
fi

systemdatabase1=information_schema
systemdatabase2=mysql
systemdatabase3=nacos
systemdatabase4=performance_schema
systemdatabase5=sys

databaseNames=`mysql -uroot -proot1234% -h${mysqlip} -P3306 -e "show databases"|awk 'NR>1{print $1}'`
for databaseName in ${databaseNames}
do
if [ $databaseName = ${systemdatabase1} ] || [ $databaseName = ${systemdatabase2} ] || [ $databaseName = ${systemdatabase3} ] ||  [ $databaseName = ${systemdatabase4} ]|| [ $databaseName = ${systemdatabase5} ]
then
 echo " ${databaseName} 不进行备份"
else
 echo " ${databaseName} 开始备份"
 mysqldump -h${mysqlip} -uroot -proot1234% --databases ${databaseName} > "${path}/${databaseName}.sql"
fi
done

6.mysql恢复脚本

#mysql还原备份脚本,执行命令如下： sh mysqlrebak.sh  2021122411  第一个参数为数据库备份的时间，精确到小时，也就是还原某小时备份的数据库
#!/bin/bash
mysqlip=192.168.25.111
mysqlbakdate=${1}
if [ -z "$mysqlbakdate" ]
then
  echo "未输入还原目录!!!"
  exit;
fi

path="/home/wowed/mysqlbak/${mysqlbakdate}"
if [ -d ${path} ]
then
  echo "备份文件夹存在"
else
  echo "备份文件夹不存在,退出程序"
  exit -1
fi
#获取路径下的所有文件
allsqlfile=$(ls $path)

#遍历文件然后还原数据库
for filename in $allsqlfile
do
 database=${filename%%.*}
 echo "开始还原数据库${database}"
 echo "${path}/${filename}"
 mysql -u root -proot1234% -h${mysqlip} <<EOF
 source ${path}/${filename};
EOF
done
exit;

7.启动脚本

# !/bin/sh
#防止shell里使用nohup不能后台运行直接挂掉
BUILD_ID=DONTKILLME
jarpath="/home/wowed/wowed-account"
#切换到jar包路径
 cd ${jarpath}
#获取当前服务的进程是否存在
pid=`ps -ef|grep wowed-account-service|grep jar|awk '{print $2}'`
 #如果存在的话
if [[ -n "$pid" ]]
    then
    echo ' 当前服务已经启动，现在进行重启操作... '
    kill -9 $pid
    killsuccess=$?
    if  [[ ${killsuccess} == '0'  ]]
       then
          echo "服务关闭成功"
          cd ${jarpath}
          nohup java -jar wowed-account-service-1.0-SNAPSHOT.jar >/dev/null 2>&1 &
      else
          echo "服务关闭失败"
    fi
else
    echo '服务进程不存在直接启动'
    cd ${jarpath}
    nohup java -jar wowed-account-service-1.0-SNAPSHOT.jar >/dev/null 2>&1 &
fi
cp /dev/null nohup.out
echo "部署完成..."
tail -200f /home/wowed/logs/wowed-account.log


8.停止脚本
#!/bin/bash
A=`pgrep -f wowed-account | wc -l`
if [ $A -gt 0 ];then
B=`pgrep -f wowed-account`
kill -9 $B
fi
