-- face 劃分 clear net monit 停止 current tab 對於多instance安裝的MYSQL來說，起停的過程相對復雜，可以定義一些簡單的腳本來簡化日常的管理。
1# 環境變量腳本
[mysql@mysql01 scripts]$ cat mysql_env.ini #set env MYSQL_USER=root MYSQL_PASS=‘password123‘ #明文保存的密碼，生產庫中當然不可以這樣使用。 COPYDIR=‘/opt/mysql‘ BASEDIR=‘/data/mysqldata‘ #check parameter if [ $# -eq 0 ] then MYSQL_PORT=3306 else MYSQL_PORT=$1 fi [mysql@mysql01 scripts]$
2# MYSQL啟動腳本
[mysql@mysql01 scripts]$ cat mysql_startup.sh
#!/bin/bash
source /data/mysqldata/scripts/mysql_env.ini
echo "Startup MySQL Service: localhost_"${MYSQL_PORT}
${COPYDIR}/bin/mysqld_safe --defaults-file=${BASEDIR}/${MYSQL_PORT}/my.cnf &
[mysql@mysql01 scripts]$3# MYSQL停止腳本
[mysql@mysql01 scripts]$ cat mysql_shutdown.sh #!/bin/bash source /data/mysqldata/scripts/mysql_env.ini echo "Shutdown MySQL Service: localhost_"${MYSQL_PORT} ${COPYDIR}/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PASS} -S ${BASEDIR}/${MYSQL_PORT}/mysql.sock shutdown [mysql@mysql01 scripts]$
4# 快速登陸
[mysql@mysql01 scripts]$ cat mysqlcmd.sh
#!/bin/bash
source /data/mysqldata/scripts/mysql_env.ini
echo "Startup MySQL CMD: localhost_"${MYSQL_PORT}
${COPYDIR}/bin/mysql -u${MYSQL_USER} -p${MYSQL_PASS} -S ${BASEDIR}/${MYSQL_PORT}/mysql.sock
[mysql@mysql01 scripts]$5# 建立軟連接
[mysql@mysql01 scripts]$ pwd /data/mysqldata/scripts [mysql@mysql01 scripts]$ ln -s mysqlcmd.sh mysqlcmd [mysql@mysql01 scripts]$ ln -s mysql_startup.sh mysqlstart [mysql@mysql01 scripts]$ ln -s mysql_shutdown.sh mysqlstop [mysql@mysql01 scripts]$ ls -ralt total 32 drwxr-xr-x. 5 mysql mysql 44 Aug 27 03:33 .. -rwxrw-r--. 1 mysql mysql 189 Aug 28 20:14 mysql_startup.sh -rwxrw-r--. 1 mysql mysql 220 Aug 28 20:19 mysql_shutdown.sh -rwxrw-r--. 1 mysql mysql 202 Aug 28 20:23 mysqlcmd.sh -rw-r--r--. 1 mysql mysql 12288 Aug 28 20:26 .mysql_shutdown.sh.swp -rw-rw----. 1 mysql mysql 176 Aug 28 20:26 mysql_env.ini lrwxrwxrwx. 1 mysql mysql 11 Aug 28 20:30 mysqlcmd -> mysqlcmd.sh lrwxrwxrwx. 1 mysql mysql 16 Aug 28 20:30 mysqlstart -> mysql_startup.sh lrwxrwxrwx. 1 mysql mysql 17 Aug 28 20:31 mysqlstop -> mysql_shutdown.sh
6# 使用過程
6.1# 確定當前運行中的MYSQL實例，以端口劃分
[mysql@mysql01 scripts]$ netstat -lnt | grep 330
tcp6 0 0 :::3306 :::* LISTEN
可以看到當前3306正在運行，停止3306
6.2# 停止MYSQL
[mysql@mysql01 scripts]$ mysqlstop 3306
Shutdown MySQL Service: localhost_3306

[mysql@mysql01 scripts]$6.3# 啟動MYSQL
[mysql@mysql01 scripts]$ mysqlstart 3306
Startup MySQL Service: localhost_3306
[mysql@mysql01 scripts]$ 180828 21:33:49 mysqld_safe Logging to ‘/data/mysqldata/3306/data/../mysql-error.log‘.
180828 21:33:49 mysqld_safe Starting mysqld daemon with databases from /data/mysqldata/3306/data
[mysql@mysql01 scripts]$
6.4# 使用MYSQL
[mysql@mysql01 scripts]$ mysqlcmd 3306
Startup MySQL CMD: localhost_3306
