实战:自己定义脚本关闭mysql-mysql 5.6.19

依据工作环境,自己定义一个mysql关闭脚本

---1.保存为/usr/local/mysql/scripts/mysql_env.ini

#set mysql init variables
MYSQL_USER=system  #mysql的username
MYSQL_PASS='password'  #mysql的登录用户密码

#check input parameter or no
if [ $# -ne 1 ] ; then     #推断输入的參数个数
 echo "mysql port is 3306"
 MYSQL_PORT=3306
else
 MYSQL_PORT=$1    #$1是传入的第1个位置參数
 echo "mysql port is $1"

fi

---2.关闭mysql

#!/bin/sh
#ocpyang@126.com

source /usr/local/mysql/scripts/mysql_env.ini

MY_CNF=/usr/local/mysql/my.cnf #mysql的配置文件

MYSQLD_ADMIN=/usr/local/mysql/bin/mysqladmin

MYSQL_SOCKET=/usr/local/mysql/mysql.sock

MYSQL_CMD="${MYSQLD_ADMIN} -u${MYSQL_USER} -p${MYSQL_PASS} -S ${MYSQL_SOCKET}"

ERRORLOG=`grep -i "^log-error" $MY_CNF |cut -d = -f 2`

INIT_NUM=1

PORTNUM=`netstat -lnt|grep ${MYSQL_PORT}|wc -l`

if [ ! -x $MYSQLD_ADMIN ]; then
  echo "mysql安装时启动文件未安装到$MYSQLD_ADMIN或无运行权限"
  exit 0
elif [ $PORTNUM = 0  ] ;then
echo "mysql处于关闭状态,无须关闭!"
exit 0
else
 echo "关闭mysql服务" 
 ${MYSQL_CMD} shutdown
 while  [ $INIT_NUM  -le 5 ]
 do
 PORTNUM=`netstat -lnt|grep ${MYSQL_PORT}|wc -l`
 echo "mysql关闭中....请稍等..."
 sleep 5
  if [ $PORTNUM = 0  ];
  then
   echo "mysql                                      ****关闭成功****"
  exit 0
  fi
 
 INIT_NUM=$(($INIT_NUM +1))
 done
   echo -e "mysql关闭失败,请检查错误日志`echo 'cat ' ${ERRORLOG}`"
 echo "*****************************************"
 exit 0
fi

---3.增加环境变量就可以

echo "export PATH=/usr/local/mysql/scripts:$PATH">>~/.bash_profile

source ~/.bash_profile
