MySQL 5.6 二進位包安裝配置多執行個體方法

標籤：

MySQL支援一台機器上啟動多個執行個體，如果你的機器效能很好的話，啟動多個執行個體將最大化利用你的伺服器硬體資源。

MySQL多執行個體一般有兩種配置方法：

1、官方推薦的mysqld_multi方式，多個執行個體共用一份設定檔

2、每個執行個體使用單獨的設定檔 (本文介紹這種方式)

軟體環境

1、SUSE Linux Enterprise Server 11 SP1

2、MySQL-5.6.26-1.sles11.x86_64.rpm-bundle

 

安裝步驟

1、安裝MySQL

#rpm -ivh MySQL-client-5.6.26-1.sles11.x86_64.rpm MySQL-server-5.6.26-1.sles11.x86_64.rpm

2、停止現有的MySQL服務

#service mysql stop

#chkconfig mysql off

3、建立多執行個體資料儲存目錄

#mkdir -p /data/mysql/{3306,3307}/data
#mkdir -p /data/mysql/{3306,3307}/log

4、在/data/mysql/3306中建立my.cnf，內容如下

[client]port=3306socket=/data/mysql/3306/mysql.sock[mysqld]port=3306socket=/data/mysql/3306/mysql.sockpid-file=/data/mysql/3306/data/mysql.pidbasedir=/usrdatadir=/data/mysql/3306/dataserver-id=1log-bin=mysql-binlog-bin-index=mysql-bin.index# LOGGINGlog_error=/data/mysql/3306/log/mysql-error.logslow_query_log_file=/data/mysql/3306/log/mysql-slow.logslow_query_log=1

5、複製/etc/rc.d/mysql啟動指令碼到/data/mysql/3306下

#cp /etc/rc.d/mysql /data/mysql/3306/

編輯/data/mysql/3306目錄下的mysql檔案，修改如下（紅色部分為修改的部分）

6、初始化資料

#mysql_install_db --defaults-file=/data/mysql/3306/my.cnf --user=mysql --datadir=/data/mysql/3306/data --force

7、啟動mysql

#/data/mysql/3306/mysql start

#ps -ef | grep mysql

8、3307的配置如3306
