06-MySQL install on centOS

https://github.com/Hackeruncle/MySQL/blob/master/MySQL%205.6.23%20Install.txt

1.Download

[root@sht-sgmhadoopnn-01 ~]# cd /usr/local

#選擇win7的mysql軟件包

[root@sht-sgmhadoopnn-01 local]# rz

2.Check isnot install

[root@sht-sgmhadoopnn-01 local]# ps -ef|grep mysqld

root? ? ? 2493? 2423? 0 19:48 pts/3? ? 00:00:00 grep mysqld

[root@sht-sgmhadoopnn-01 local]# rpm -qa |grep -i mysql

3.tar and mv

[root@sht-sgmhadoopnn-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

[root@sht-sgmhadoopnn-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

4.Create group and user

[root@sht-sgmhadoopnn-01 local]# groupadd -g 101 dba

[root@sht-sgmhadoopnn-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

[root@sht-sgmhadoopnn-01 local]# id mysqladmin

uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)

生產(chǎn)環(huán)境: 給你的用戶肯定不是root，給jepson/123456 (sudo/不帶sudo)

sudo: 創(chuàng)建一個(gè)mysql服務(wù)的管理的用戶

不 sudo: IT 給你的用戶開啟sudo權(quán)限

為什么要?jiǎng)?chuàng)建mysqladmin/dba沸久？

1.一個(gè)用戶只對(duì)一個(gè)組件

2.dba組

要postgresql骤宣，pgadmin/dba

#[root@sht-sgmhadoopnn-01 local]# passwd mysqladmin

Changing password for user mysqladmin.

New UNIX password:

BAD PASSWORD: it is too simplistic/systematic

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

[root@sht-sgmhadoopnn-01 local]#

## if user mysqladmin is existing,please execute the following command of usermod.

#[root@sht-sgmhadoopnn-01 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #

## copy 環(huán)境變量配置文件至mysqladmin用戶的home目錄中,為了以下步驟配置個(gè)人環(huán)境變量

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

? ./bin/mysqladmin -u root password 'new-password'

? ./bin/mysqladmin -u root -h sht-sgmhadoopnn-01 password 'new-password'

Alternatively you can run:

? ./bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.? This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

? cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

? cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

The latest information about MySQL is available on the web at

? http://www.mysql.com

Support MySQL by buying support/licenses at http://shop.mysql.com

New default config file was created as ./my.cnf and

will be used by default by the server when you start it.

You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system

This file will be read by default by the MySQL server

If you do not want to use this, either remove it, or use the

--defaults-file argument to mysqld_safe when starting the server

8.Configure mysql service and boot auto start

[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql

#將服務(wù)文件拷貝到init.d下，并重命名為mysql

[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql

#賦予可執(zhí)行權(quán)限

[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql

#刪除服務(wù)

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql

#添加服務(wù)

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on

9.Start mysql and to view process and listening

[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin

[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd

/usr/local/mysql
