根据工作环境,自定义一个mysql关闭脚本

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

#set mysql init variables
MYSQL_USER=system   #mysql的用户名
MYSQL_PASS=‘password‘  #mysql的登录用户密码

#check input parameter or no
if [ $# -ne 1 ] ; then     #判断输入的参数个数
echo "mysql port is 3306"
MYSQL_PORT=3306
else
MYSQL_PORT=$1    #$1是传入的第1个位置参数
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或无执行权限"
 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.加入环境变量即可

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

source ~/.bash_profile
