CentOS6.5下MySQL5.6的安裝

4.建立使用者組和使用者

[root@hadoop001 local]# groupadd -g 101 dba
[root@hadoop001 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@hadoop001 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@hadoop001 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.

5.修改使用者的執行許可權
[root@hadoop001 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin 

6.配置個人環境變數（copy 環境變數配置檔案至mysqladmin使用者的home目錄中）
[root@hadoop001 local]# cp /etc/skel/.* /usr/local/mysql  
cp: omitting directory `/etc/skel/.'
cp: omitting directory `/etc/skel/..'
cp: omitting directory `/etc/skel/.mozilla'

7.vi  /etc/my.cnf ,把下列內容複製進去
(預設： /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf )
[root@hadoop001 ~]# vi /etc/my.cnf

注意：修改innodb_buffer_pool_size的引數

7.第一次安裝更改檔案歸屬

[root@hadoop001 local]# chown  mysqladmin:dba /etc/my.cnf 
[root@hadoop001 local]# chmod  640 /etc/my.cnf  
[root@hadoop001 etc]# ll my.cnf
-rw-r----- 1 mysqladmin dba 2201 Aug 25 23:09 my.cnf

[root@hadoop001 local]# chown -R mysqladmin:dba /usr/local/mysql
[root@hadoop001 local]# chmod -R 755 /usr/local/mysql 
[root@hadoop001 local]# su - mysqladmin 
[mysqladmin@hadoop001 ~]$ pwd
/usr/local/mysql
[mysqladmin@hadoop001 ~]$ mkdir arch

8.第一次安裝

[mysqladmin@hadoop001 ~]$ scripts/mysql_install_db  --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

[root@hadoop001 local]# cat /proc/version

[root@hadoop001 local]# rpm -qa |grep gcc

[root@hadoop001 local]# yum -y install libaio
[root@hadoop001 ~]# cd /usr/local/mysql
#將服務檔案複製到init.d下，並重新命名為mysql
[root@hadoop001 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 
#賦予可執行許可權
[root@hadoop001 mysql]# chmod +x /etc/rc.d/init.d/mysql
#刪除服務
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql
#新增服務
[root@0hadoop001 mysql]# chkconfig --add mysql
[root@hadoop001 mysql]# chkconfig --level 345 mysql on

11.Start mysql and to view process and listening
[root@hadoop001 mysql]# su - mysqladmin
[mysqladmin@hadoop001 ~]$ pwd
/usr/local/mysql
[mysqladmin@hadoop001 ~]$ rm -rf my.cnf
[mysqladmin@sht-sgmhadoopnn-01 ~]$ bin/mysqld_safe &    

先解除安裝
[root@rzdatahadoop001 lib]# rpm --nodeps -e mysql-libs-5.1.71-1.el6.x86_64
改許可權
[root@rzdatahadoop001 mysql]# chmod -R 757 /var/log 

[mysqladmin@sht-sgmhadoopnn-01 ~]$ 150825 22:53:38 mysqld_safe Logging to '/usr/local/mysql/data/hostname.err'.

14. 啟動服務
[mysqladmin@hadoop001 ~]$ ps -ef|grep mysqld
