本文是在CentOS7系統平臺下安裝Mysql5.6.26版本數據庫的操作說明，如有錯誤，請指正。
系統平臺：CentOS-7-x86_64
數據庫版本：mysql-5.6.26
Mysql鏡像文件下載地址：http://dev.mysql.com/downloads/mirrors.html
本次演示的Mysql安裝包版本：mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz
1、添加mysql用戶組及mysql用戶
[root@localhost ~]# groupadd mysql [root@localhost ~]# useradd -r -g mysql mysql
2、將二進制文件解壓到指定的安裝目錄：/usr/local/mysql
到mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz包的目錄下，解壓到/usr/local目錄下：
[root@localhost tmp]# tar zxvf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
到/usr/local/目錄中，重命名解壓出來的目錄名，改為mysql：
[root@localhost tmp]# cd /usr/local/ [root@localhost local]# mv mysql-5.6.26-linux-glibc2.5-x86_64 mysql
查看此目錄下文件：
[root@localhost local]# cd mysql/ [root@localhost mysql]# ls bin data include lib mysql-test scripts sql-bench COPYING docs INSTALL-BINARY man README share support-files
注：/usr/local/mysql/下的目錄結構

3、創建mysql數據存放的目錄：/data/mysql
[root@localhost mysql]# mkdir -p /data/mysql
4、更改所屬的組和用戶
[root@localhost mysql]# chown -R mysql:mysql /usr/local/mysql/ [root@localhost mysql]# chown -R mysql:mysql /data/mysql/
5、初始化mysql
注釋：以mysql用戶執行mysql_install_db腳本，基本目錄為：/usr/local/mysql/，數據文件目錄為：/data/mysql/

To do so, start the server, then issue thefollowing commands: /usr/local/mysql//bin/mysqladmin -u root password 'new-password' /usr/local/mysql//bin/mysqladmin -u root -h localhost.localdomainpassword 'new-password' Alternatively you can run: /usr/local/mysql//bin/mysql_secure_installation which will also give you the option ofremoving the test databases and anonymous user created bydefault. This is strongly recommended for productionservers. See the manual for more instructions. You can start the MySQL daemon with: cd. ; /usr/local/mysql//bin/mysqld_safe & You can test the MySQL daemon withmysql-test-run.pl cdmysql-test ; perl mysql-test-run.pl Please report any problems athttp://bugs.mysql.com/ The latest information about MySQL isavailable on the web at http://www.mysql.com Support MySQL by buying support/licenses athttp://shop.mysql.com New default config file was created as/usr/local/mysql//my.cnf and will be used by default by the server whenyou start it. You may edit this file to change serversettings WARNING: Default config file /etc/my.cnfexists on the system This file will be read by default by theMySQL server If you do not want to use this, eitherremove it, or use the --defaults-file argument to mysqld_safewhen starting the server
注：本次啟動有一個報錯如下：
FATAL ERROR: please install the followingPerl modules before executing ./scripts/mysql_install_db:
Data::Dumper
解決方案：
[root@localhost mysql]# yum install -yperl-Module-Install.noarch
6、修改my.cnf配置文件
復制/usr/local/mysql/support-files/my-default.conf 文件到/etc/ 目錄下，覆蓋原有的配置文件mysql/my.cnf：
[root@localhost mysql]# cp support-files/my-default.cnf /etc/my.cnf
修改/etc/my.cnf 文件，指定datadir、basedir 路徑，同時開啟3306端口：
basedir = /usr/local/mysql datadir = /data/mysql port = 3306
7、復制mysql 啟動腳本mysql.server 到/etc/init.d/mysqld
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
8、修改啟動腳本的權限為755，賦予執行權限
[root@localhost mysql]# chmod 755 /etc/init.d/mysqld
9、通過chkconfig命令將mysqld服務加入到自啟動服務項中：
[root@localhost init.d]# pwd /etc/init.d [root@localhost init.d]# chkconfig --add mysqld
檢查是否加入到自動啟動
[root@localhost init.d]# chkconfig --list mysqld mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
10、啟動mysql服務：
[root@localhost mysql]# service mysqld start Starting MySQL... SUCCESS!
11、進入mysql
[root@localhost mysql]#/usr/local/mysql/bin/mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.6.26 MySQL CommunityServer (GPL) Copyright (c) 2000, 2015, Oracle and/or itsaffiliates. All rights reserved. Oracle is a registered trademark of OracleCorporation and/or its affiliates. Other names may be trademarksof their respective owners. Type 'help;' or '\h' for help. Type '\c' toclear the current input statement. mysql>
注：在/etc/profile中加入以下環境變量，可以用mysql代替/usr/local/mysql/bin/mysql啟動
MYSQL_HOME=/usr/local/mysql
exportPATH=$PATH:$MYSQL_HOME/bin
設置后需要重新加載一下：
[root@localhost mysql]# source /etc/profile
再次進入mysql
[root@localhost mysql]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.6.26 MySQL Community Server (GPL) Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.
