CentOS 6.5 二进制安装MySQL 5.6
1:查看系统版本
[root@10-4-5-9 mysql]# cat /etc/redhat-release CentOS release 6.5 (Final)
2:下载MySQL5.6二进制包
#wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.20-linux-glibc2.5-i686.tar.gz
3:添加用户和组
#groupadd mysql #useradd -g mysql mysql
4:安装mysql到/usr/local/mysql下
#cd /usr/local #tar zxvf /{MySQL5.6_path}/mysql-{version}.tar.gz 例如我的配置路径为: #cd /usr/local #tar zxvf /root/mysql-5.6.20-linux-glibc2.5-i686.tar.gz
5:修改解压后文件夹名为 mysql
#mv mysql-5.6.20-linux-glibc2.5-i686 mysql
6:修改mysql的各级文件夹和文件的创建者、创建组为mysql(注意语句后面有个.)
cd mysql chown -R mysql . chgrp -R mysql .
7:至此mysql已经安装完了,但还需要初始化,初始化mysql表、test表、infomation表等。
#scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
#cp support-files/mysql.server /etc/init.d/mysqld
--user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
PS:该步骤有可能会报错误 安装需要的包即可:libstdc++.so.6和libaio.so.1和libncurses.so.5
8:修改配置文件
[root@10-4-5-9 mysql]# cp my.cnf /etc/my.cnf /usr/local/mysql [root@10-4-5-9 mysql]# vi /etc/my.cnf
[mysqld]中添加: basedir = /usr/local/mysql datadir = /usr/local/mysql/data port = 3306 server_id = 1
9:启动mySQL服务
#ln -s /usr/local/mysql/bin/mysql /usr/bin
#service mysqld start
10:登陆MySQL并且删除空用户
