修改啟動腳本的權限

find?/data?-type?f?-name?"mysql"|xargs?chmod?700

授權mysql用戶管理/data目錄

chown?-R?mysql.mysql?/data

初使化數據庫

cd?/application/mysql/scripts/ ./mysql_install_db?--user=mysql?--basedir=/application/mysql?--datadir=/data/3306/data/ ./mysql_install_db?--user=mysql?--basedir=/application/mysql?--datadir=/data/3307/data/

啟動多實例，加入開機自啟動

/data/3306/mysql?start /data/3307/mysql?start netstat?-tunlp?|grep?330#?echo命令的?-e參數處理特殊字符；\n?換行且光標移至行首 echo?-e?"\n##mysql?multi?instance\n/data/3306/mysql?start\n/data/3307/mysql?start">>/etc/rc.localtail?-3?/etc/rc.local ##mysql?multi?instance /data/3306/mysql?start /data/3307/mysql?start

設置環境變量

方法一：將mysql的相關命令放入到已經是環境變量的目錄下（推薦！！）

cp?/application/mysql/bin/*?/usr/local/bin/

方法二

export?PATH=/application/mysql-5.5.49/bin/:$PATH echo?'export?PATH=/application/mysql-5.5.49/bin/:$PATH'?>>/etc/profile tail?-1?/etc/profile source?/etc/profile echo?$PATH

登錄與退出多實例

多實例的登錄(無密碼)

mysql?-S?/data/3306/mysql.sock mysql?-S?/data/3307/mysql.sock

退出登錄（4種）

mysql>?exit mysql>?quit mysql>?Ctrl?+?c mysql>?Ctrl?+?d

設置密碼

mysqladmin?-uroot?password?'oldboy123'?-S?/data/3306/mysql.sock mysqladmin?-uroot?password?'oldboy123'?-S?/data/3307/mysql.sock

更改密碼為：oldboy456

mysqladmin?-uroot?-poldboy123?password?'oldboy456'?-S?/data/3306/mysql.sock

多實例的登錄(有密碼)

mysql?-uroot?-poldboy123?-S?/data/3306/mysql.sock mysql?-uroot?-poldboy123?-S?/data/3307/mysql.sock

再加一個實例3308

mkdir?/data/3308/data?-p cp?/data/3306/{my.cnf,mysql}?/data/3308/ sed?-i?'s#3306#3308#g'?/data/3308/{my.cnf,mysql} sed?-i?'s#server-id?=?1#server-id?=?8#g'?/data/3308/my.cnf chown?-R?mysql.mysql?/data/3308 chmod?700?/data/3308/mysql cd?/application/mysql-5.5.49/scripts/ ./mysql_install_db?--user=mysql?--basedir=/application/mysql?--datadir=/data/3308/data/ /data/3308/mysql?start echo?"/data/3308/mysql?start"?>>/etc/rc.local netstat?-tunpl?|grep?330 mysql?-S?/data/3308/mysql.sock mysqladmin?-uroot?password?'oldboy123'?-S?/data/3308/mysql.sock mysql?-uroot?-poldboy123?-S?/data/3308/mysql.sock

MySQL多實例優化

清理無用的MySQL庫（3306）

mysql?-uroot?-poldboy123?-S?/data/3306/mysql.sock drop?database?test; show?databases;

清理無用的MySQL用戶

select?user,host?from?mysql.user; drop?user?"root"@"::1"; drop?user?"?"@"db02";? drop?user?"root"@"db02"; drop?user?"?"@"localhost";

故障：drop命令刪除不了用戶

可能是大寫及Linux主機名導致的，注意：刪除用戶盡量用drop命令，不要用delete命令

解決方法如下：

delete?from?mysql.user?where?user=''?and?host='S1';???? delete?from?mysql.user?where?user='root'?and?host='S1';

刷新權限

刷新權限，使更改立馬生效

flush?privileges;
