标签：使用   rtu   复杂   mysql   err   pre   停止   nec   port   

1# 环境变量脚本

[mysql@mysql01 scripts]$ cat mysql_env.ini
#set env
MYSQL_USER=root
MYSQL_PASS=‘password123‘    #明文保存的密码，生产库中当然不可以这样使用。

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启动脚本

[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停止脚本

[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# 快速登陆

[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# 建立软连接

[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# 使用过程
6.1# 确定当前运行中的MYSQL实例，以端口划分

[mysql@mysql01 scripts]$ netstat -lnt | grep 330
tcp6       0      0 :::3306                 :::*                    LISTEN

可以看到当前3306正在运行，停止3306
6.2# 停止MYSQL

[mysql@mysql01 scripts]$ mysqlstop 3306
Shutdown MySQL Service: localhost_3306
Warning: Using a password on the command line interface can be insecure.
[mysql@mysql01 scripts]$

6.3# 启动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
