centos7环境下二进制安装包安装 mysql5.6的方法详解

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

[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

?

1 2 3 4 5 6

> 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 |
+------+-----------------------+

?

1 2 3 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。
