系统平台：
CentOS release 7.4 (Final) 内核 3.10.0-693.el7.x86_64
1.去官网下载二进制包
https://dev.mysql.com/downloads/mysql/
2.创建用于启动mysql的账号和组
#getent group mysql > /dev/null || groupadd mysql
#getent passwd mysql > /dev/null || useradd -g mysql -r -s /sbin/nologin mysql
3.解压包至/usr/local
#tar xvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
4.创建软链接mysql指向解压后的目录
#cd /usr/local/
#ln -sv mysql-5.6.39-linux-glibc2.12-x86_64/ mysql
5.修改mysql文件夹所属者和所属组
#chown -R mysql.mysql mysql/
6.添加PATH至环境变量中
#echo 'PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile.d/mysql.sh
检查文件
#cat /etc/profile.d/mysql.sh
加载环境变量文件 并检查
#source /etc/profile.d/mysql.sh
#echo $PATH
7.创建数据库存放文件夹和相关文件并修改权限
# mkdir -pv /data/mysqldb/3306/{logs,bin-logs,run,data}
# touch /data/mysqldb/3306/run/mysqld.pid
# touch /data/mysqldb/3306/logs/mysql-error.log
# chown -R mysql.mysql /data/mysqldb/ -R
# chmod -R 770 /data/mysqldb/
# chown -R mysql.mysql /data/mysqldb/
# chmod -R 770 /data/mysqldb
文件没有创建的话，启动Mysql时将会报错
8.修改配置文件
#vim /etc/my.cnf
[client]
port = 3306
socket = /tmp/mysql.sock
default-character-set=utf8
[mysqld]
user = mysql
port = 3306
basedir=/usr/local/mysql
datadir = /data/mysqldb/3306/data
socket = /tmp/mysql.sock
log-bin = /data/mysqldb/3306/bin-logs/mysql-bin
binlog_format=mixed
symbolic-links=0
innodb_file_per_table = 1
skip_name_resolve = 1
slow_query_log = 1
long_query_time = 2
pid-file = /data/mysqldb/3306/run/mysqld.pid
log-error = /data/mysqldb/3306/logs/mysql-error.log
character-set-server=utf8
default-storage-engine=INNODB
[mysqld_safe]
# include all files from the config directory
#
!includedir /etc/my.cnf.d
9.初始化数据库
# cd /usr/local/mysql
# bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --datadir=/data/mysqldb/3306/data
10.复制启动服务脚本至/etc/init.d目录（小坑）
使用二进制安装包里面的support-files/mysql.server这个启动脚本死活不能启动，报以下错误
Starting MySQL. ERROR! The server quit without updating PID file (/data/mysqldb/3306/run/mysqld.pid).
无奈之下，去mysql官网下载一个mysql的源码包，使用里面的mysql.server就没问题。呵呵。
#cp mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
11.添加开机启动
# chkconfig --add mysqld
# chkconfig mysqld on
#chkconfig --list mysqld
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
12.启动mysql服务
#service mysqld start
Starting MySQL. SUCCESS!
13.检查确认
检查3306端口是否开启
#ss -ntl | grep 3306
LISTEN 0 50 *:3306 *:*
确认版本
# mysql -V
mysql Ver 14.14 Distrib 5.6.39, for linux-glibc2.12 (x86_64) using EditLine wrapper
14.进行安全配置
#/usr/local/mysql/bin/mysql_secure_installation
按提示操作即可
15.客户端连接
#mysql -uroot -p
