CentOS 7.4 自定义单实例 二进制方式 安装mysql5.6.39

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 = 3306socket = /tmp/mysql.sockdefault-character-set=utf8[mysqld]user = mysqlport = 3306basedir=/usr/local/mysqldatadir = /data/mysqldb/3306/datasocket = /tmp/mysql.socklog-bin = /data/mysqldb/3306/bin-logs/mysql-binbinlog_format=mixedsymbolic-links=0innodb_file_per_table = 1skip_name_resolve = 1slow_query_log = 1long_query_time = 2pid-file = /data/mysqldb/3306/run/mysqld.pidlog-error = /data/mysqldb/3306/logs/mysql-error.logcharacter-set-server=utf8default-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 mysqldmysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off

12.启动mysql服务

#service mysqld startStarting MySQL. SUCCESS!

13.检查确认

检查3306端口是否开启

#ss -ntl | grep 3306LISTEN     0      50                        *:3306                     *:*

确认版本

# mysql -Vmysql  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
