安裝MYSQL5.6

2015.09.21

最近公司某個項目要用mysql5.6版本，又要整理份安裝文檔。真心不愛寫安裝文檔類，貼于此。

1. 安裝必要的組件

1 2	# yum install –y autoconf automake imake libxml2-devel\ expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel

2. 下載解壓mysql軟件

# cd /usr/local/src

# wget -c http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz/from/http://cdn.mysql.com/ -O mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz

# tar zxvf mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz –C ../

# cd /usr/local/

# ln -s mysql-5.6.14-linux-glibc2.5-x86_64 mysql

3. 創(chuàng)建Mysql用戶組和用戶，及數據庫存放目錄：

# mkdir -p /data/mysql_data_3306

# mkdir -p /data/mysql_log

# mkdir -p /data/log-bin

# groupadd mysql

# useradd mysql -g mysql -M -s /sbin/nologin

# chown -R mysql.mysql /data/mysql_data_3306 /data/mysql_log /data/log-bin

# chown -R mysql.mysql /usr/local/mysql-5.6.14-linux-glibc2.5-x86_64

4. 配置文件（依具體環(huán)境）

# vi /etc/my.cnf

# cp -af /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld_3306

# vi /etc/init.d/mysqld_3306

修改兩處位置：

basedir=/usr/local/mysql

datadir=/data/mysql_data_3306

執(zhí)行如下命令

# chmod 755 /etc/init.d/mysqld_3306
