本文实例讲述了centos7环境下二进制安装包安装 MySQL5.6的方法。分享给大家供大家参考，具体如下：
centos7 二进制安装包安装 mysql5.6
一、下载mysql5.6二进制安装包
http://mirrors.sohu.com/mysql/MySQL-5.6/
如:mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
二、安装mysql5.6(安装在/data/mysql56)
(1)、创建mysql用户账号
> useradd -s /sbin/nologin -M mysql
(2)、解压压缩包
> tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
(3)、重命名
> mv mysql-5.6.34-linux-glibc2.5-x86_64 mysql56
(4)、复制配置文件
> cp /data/mysql56/support-files/my-default.cnf /etc/my.cnf
修改配置文件
[client] port = 3306 socket = /data/mysql56/mysql.sock default-character-set = utf8 [mysqld] skip-name-resolve user = mysql basedir = /data/mysql56 datadir = /data/mysql56/data port = 3306 server_id = 10 socket = /data/mysql56/mysql.sock pid-file = /data/mysql56/mysql.pid log-error = /data/mysql56/data/mysql.err log-bin = /data/mysql56/data/mysql-bin character-set-server = utf8
(*二进制安装，默认配置文件在/etc/my.cnf)
(5)、初始化数据库
> chown -R mysql.mysql /data/mysq56 > /data/mysql56/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql --basedir=/data/mysql56 --datadir=/data/mysql56/data
如果出现如下信息
FATAL ERROR: please install the following Perl modules before executing
Data::Dumper
> yum -y install autoconf
此包安装时会安装Data:Dumper模块
三、配置并启动mysql
> cp /data/mysql56/support-files/mysql.server /etc/init.d/mysqld > chmod 755 /etc/init.d/mysqld
(*注意,mysql二进制安装默认的路径为/usr/local/mysql,启动脚本里/usr/local/mysql需要替换)
> sed -i 's#/usr/local/mysql#/data/mysql56#g' /data/mysql56/bin/mysqld_safe /etc/init.d/mysqld
启动mysql
> service mysqld start
四、添加自启动
> chkconfig --add mysqld > chkconfig mysqld on > chkconfig --list mysqld
五、配置环境变量
> echo 'export PATH=/data/mysql56/bin:$PATH' >> /etc/profile > source /etc/profile
六、修改mysql密码(mysql5.6安装默认root密码为空)
> mysqladmin -u root password '123456'
七、清理无用的mysql用户及库
登陆mysql
> mysql -uroot -p
查询用户
> select user,host from mysql.user;
如下所示
+------+-----------------------+
| user | host |
+------+-----------------------+
| root | 127.0.0.1 |
| root | ::1 |
| | localhost |
| root | localhost |
| | localhost.localdomAIn |
| root | localhost.localdomain |
+------+-----------------------+
> drop user "root"@"::1"; > drop user ""@"localhost"; > drop user ""@"localhost.localdomain"; > drop user "root"@"localhost.localdomain";
删除无用库
> drop database test;
