centos7 二進制安裝包安裝 mysql5.6

centos7 二進制安裝包安裝 mysql5.6

一、下載mysql5.6二進制安裝包

http://mirrors.sohu.com/mysql/MySQL-5.6/

如:mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz

二、安裝mysql5.6(安裝在/data/mysql56)

(1)、創建mysql用戶賬號

> useradd -s /sbin/nologin -M mysql

(2)、解壓壓縮包

> 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)、復制配置文件

> 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

(*二進制安裝，默認配置文件在/etc/my.cnf)

(5)、初始化數據庫

> 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

如果出現如下信息

FATAL ERROR: please install the following Perl modules before executing
Data::Dumper

> yum -y install autoconf

此包安裝時會安裝Data:Dumper模塊

三、配置並啟動mysql

> cp /data/mysql56/support-files/mysql.server /etc/init.d/mysqld
> chmod 755 /etc/init.d/mysqld

(*注意,mysql二進制安裝默認的路徑為/usr/local/mysql,啟動腳本里/usr/local/mysql需要替換)

> sed -i 's#/usr/local/mysql#/data/mysql56#g' /data/mysql56/bin/mysqld_safe /etc/init.d/mysqld

啟動mysql

> service mysqld start

 
四、添加自啟動

> chkconfig --add mysqld
> chkconfig mysqld on
> chkconfig --list mysqld

 
五、配置環境變量

> echo 'export PATH=/data/mysql56/bin:$PATH' >> /etc/profile
> source /etc/profile

 
六、修改mysql密碼(mysql5.6安裝默認root密碼為空)

> mysqladmin -u root password '123456'

七、清理無用的mysql用戶及庫
登陸mysql

> mysql -uroot -p

查詢用戶

> 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";

刪除無用庫

> drop database test;
