CentOS6.5安裝mysql5.6-GA版

mysql5.6-GA版是mysql5.6的最終穩定版本,故選擇該版本做爲教程目標進行安裝。node

如下爲安裝步驟:mysql

一、先查看系統是否存在已有的mysqllinux

rpm -qa | grep mysql

二、刪除已存在的mysqlsql

rpm -e mysql --nodeps

三、下載並解壓mysql包bash

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-5.6.31-1.linux_glibc2.5.x86_64.rpm-bundle.tar
tar -zxvf MySQL-5.6.31-1.linux_glibc2.5.x86_64.rpm-bundle.tar

四、依次安裝tar包中的三個包
    a.MySQL-client-5.6.31-1.linux_glibc2.5.x86_64.rpm
    b.MySQL-server-5.6.31-1.linux_glibc2.5.x86_64.rpm
    c.MySQL-devel-5.6.31-1.linux_glibc2.5.x86_64.rpm
    
五、rpm安裝,mysql會生成root用戶的隨機密碼,在/root下socket

cat /root/.mysql_secret

六、使用此密碼進入mysql控制檯tcp

mysql -u root -p

七、修改root密碼ide

mysql>set password for 'root'@'localhost'=password('newpasswd');

八、開啓mysql遠程訪問code

grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
flush privileges;
exit;

9.配置mysql配置文件
    a.從/usr/share/mysql/處,拷貝my-default.cnf到/etc:server

cp /usr/share/mysql/my-default.cnf /etc/my.cnf

    b.修改相應配置(如中文亂碼等),如下是簡單的配置

[mysqld]
port = 3306
character_set_server=utf8

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
symbolic-links=0


max_allowed_packet = 10M
slave_max_allowed_packet = 10M

[mysqld_safe]
default-character-set = utf8

[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
default-character-set=utf8

[mysql.server]
default-character-set = utf8

[mysql]
no-auto-rehash
default-character-set = utf8

    c.重啓mysql服務

10.開啓防火牆3306端口

iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
