MYSQL5.6在centos7.0安裝步驟

1.Download

    1）在線下載 

      [root@hadoop05 local]#  wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

    2）或者本地上傳

       選擇win的的mysql軟件包

[root@hadoop05 local]#  rz

 

 在/usr/local目錄下安裝mysql

[root@hadoop05 local]#  cd /usr/local  在這個目錄下

 

2.Check isnot install

查看mysql進程

[root@hadoop05 local]#  ps -ef|grep mysqld

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

查看是否有安裝mysql

[root@hadoop05 local]#  rpm -qa |grep -i mysql

 

3.tar and mv

解壓tar文件

[root@hadoop05 local]#  tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

重命名文件

[root@hadoop05 local]#  mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

 

4.Create group and user

[root@hadoop05 local]#  groupadd -g 101 dba

[root@hadoop05 local]#  useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

[root@hadoop05 local]#  id mysqladmin

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

 

生產環境注意:

      給你的用戶確定不是root，給普通用戶/123456 (sudo/不帶sudo)

sudo: 建立一個mysql服務的管理的用戶

不 sudo: IT 給你的用戶開啓sudo權限

 

爲何要建立mysqladmin/dba？

1.一個用戶只對一個組件

2.dba組

  要postgresql，pgadmin/dba

 

 

能夠不用作

[root@hadoop05 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@hadoop05 local]#

能夠不用作

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

[root@hadoop05 local]#  usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #

 

 

## copy 環境變量配置文件至mysqladmin用戶的home目錄中,爲了如下步驟配置我的環境變量

[root@hadoop05 local]#  cp /etc/skel/.* /usr/local/mysql  ###這步很important

cp: omitting directory `/etc/skel/.'

cp: omitting directory `/etc/skel/..'

cp: omitting directory `/etc/skel/.mozilla'

 

5.Create /etc/my.cnf(640)

#defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf

[root@hadoop05 local]#  ll my.cnf

[root@hadoop05 local]#  chown -R mysqladmin:dba /usr/local/mysql

[root@hadoop05 local]#  su - mysqladmin

[root@hadoop05 local]#  pwd

/usr/local/mysql

[root@hadoop05 local]#  mkdir arch 

 

第一次安裝

OK

 

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:

 

  /usr/local/mysql/bin/mysqladmin -u root password 'new-password'

  /usr/local/mysql/bin/mysqladmin -u root -h hadoop05 password 'new-password'

 

Alternatively you can run:

 

  /usr/local/mysql/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 . ; /usr/local/mysql/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/

WARNING: Found existing config file /usr/local/mysql/my.cnf on the system.

Because this file might be in use, it was not replaced,

but was used in bootstrap (unless you used --defaults-file)

and when you later start the server.

The new default config file was created as /usr/local/mysql/my-new.cnf,

please compare it with your file and take the changes you need.

 

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@hadoop05 ~]# cd /usr/local/mysql

#將服務文件拷貝到init.d下，並重命名爲mysql

[root@hadoop05 mysql]#  cp support-files/mysql.server /etc/rc.d/init.d/mysql

#賦予可執行權限

[root@hadoop05 mysql]# chmod +x /etc/rc.d/init.d/mysql

#刪除服務

[root@hadoop05 mysql]# chkconfig --del mysql

#添加服務

[root@hadoop05 mysql]# chkconfig --add mysql

[root@hadoop05 mysql]# chkconfig --level 345 mysql on

[root@hadoop05 mysql]# vi /etc/rc.local

#!/bin/sh

#

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

 

touch /var/lock/subsys/local

su - mysqladmin -c "/etc/init.d/mysql start --federated"

"/etc/rc.local" 9L, 278C written

 

 

9.Start mysql and to view process and listening

 

[root@hadoop05 mysql]# su - mysqladmin

[mysqladmin@hadoop05 ~]$ pwd

/usr/local/mysql

[mysqladmin@hadoop05 ~]$  rm -rf my.cnf

[mysqladmin@hadoop05 ~]$ bin/mysqld_safe &
