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
2
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 |
+------+-----------------------+
|

4
|
> 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。
