一、下载mysql5.6二进制安装包

下载地址 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

(1)、创建mysql用户账号

useradd -s /sbin/nologin -M mysql

(2)、解压压缩包

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)、复制配置文件

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
(*二进制安装，默认配置文件在/etc/my.cnf)

(5)、初始化数据库

yum -y install autoconf
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

三、配置并启动mysql

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)
sed -i ‘s#/usr/local/mysql#/data/mysql56#g’ /data/mysql56/bin/mysqld_safe /etc/init.d/mysqld
启动mysql
systemctl start mysqld

四、添加自启动

chkconfig —add mysqld
chkconfig mysqld on
chkconfig —list mysqld
systemctl enbale mysqld

五、配置环境变量

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)

mysqladmin -u root password ‘123456’
