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
1
|
> useradd -s /sbin/nologin -M mysql |
(2)、解压压缩包
1
|
> tar xf mysql-5.6.34-linux-glibc2.5-x86_64. tar .gz |
(3)、重命名
1
|
> mv mysql-5.6.34-linux-glibc2.5-x86_64 mysql56 |
(4)、复制配置文件
1
|
> 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
1
|
> yum -y install autoconf |
此包安装时会安装Data:Dumper模块
三、配置并启动mysql
1
2
|
> 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)
1
|
> sed -i 's#/usr/local/mysql#/data/mysql56#g' /data/mysql56/bin/mysqld_safe /etc/init .d /mysqld |
启动mysql
1
|
> service mysqld start |
四、添加自启动
1

3
|
> chkconfig --add mysqld > chkconfig mysqld on > chkconfig --list mysqld |
五、配置环境变量
1
2
|
> 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)
1
|
> mysqladmin -u root password '123456' |
七、清理无用的mysql用户及库
登陆mysql
1
|
> mysql -uroot -p |
查询用户
1
|
> 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
1
|
> drop database test ; |
希望本文所述对大家MySQL数据库计有所帮助。
