Percona Server 5.6 Install （基于RPM包）

       MySQL的安装方式一般分三种：基于RPM包安装，基于二进制包安装，基于源代码安装。不同的安装方式，

所有的知识面不一样。其实基于RPM包安装方便快捷，目录结构固定。因此，对于一般使用来说已足够。

1.安装RPM包

[root@localhost PerconaServerRPM]# rpm -ivh Percona-Server-shared-56-5.6.28-rel76.1.el6.x86_64.rpm 

[root@localhost PerconaServerRPM]# rpm -ivh Percona-Server-client-56-5.6.28-rel76.1.el6.x86_64.rpm 

[root@localhost PerconaServerRPM]# rpm -ivh Percona-Server-server-56-5.6.28-rel76.1.el6.x86_64.rpm

2.安装路径布局

Directory	Contents of Directory
/usr/bin	Client programs and scripts
/usr/sbin	The mysqld server
/var/lib/mysql	Log files, databases
/usr/share/info	MySQL manual in Info format
/usr/share/man	Unix manual pages
/usr/include/mysql	Include (header) files
/usr/lib/mysql	Libraries
/usr/share/mysql	Miscellaneous support files, including error messages, character set files, sample configuration files, SQL for database installation
/usr/share/sql-bench	Benchmarks

• 数据库目录  /var/lib/mysql/
• 配置文件     /usr/share/mysql （mysql.server命令及配置文件）
• 相关命令    /usr/bin             (mysql,mysqladmin mysqldump等命令)
• 启动脚本     /etc/rc.d/init.d/（启动脚本文件mysql的目录）

3.创建数据MySQL的数据目录

  #cd /arp

  #mkdir data

4.迁移数据库的数据目录至/data目录中，输入如下命令

  #mv /var/lib/mysql/ /arp/data/

  如新建，可删除上述数据目录

  #rm -rf /arp/data/*

5.拷贝完后还需要修改/etc/rc.d/init.d/mysql的datadir目录值，我修改如下：

----------------修改内容----------------

  basedir=

  datadir=/arp/data/3306

# Set some defaults

  mysqld_pid_file_path=/arp/data/3306/mysql.pid

----------------------------------------------

6.建立所需的数据目录

#cd /arp/data/

#mkdir -p /arp/data/{3306/{data,tmp,binlog,innodb_ts,innodb_log},backup,scripts}

#chown -R mysql:mysql 3306

#su - mysql

7.编辑配置my.cnf文件

#vim  /etc/my.cnf

保存my.cnf文件。

8.初始化MySQL数据库 
#mysql_install_db --user=mysql --datadir=/arp/data/3306/data

9.启动MySQL数据库(两种方式)

#service mysql start

#mysqld_safe --defaults-file=/etc/my.cnf & 

10.关闭MySQL数据库

#service mysql stop

#mysqladmin -u${MYSQL_USER} -p${MYSQL_PASS} shutdown 

Note:***************************************如遇下列报错场景******************************************

[root@localhost 3306]# service mysql start

Starting MySQL (Percona Server)...The server quit without u[FAILED]PID file (/arp/data/3306/tmp/mysql.pid).

解决方式：

*关闭selinux

#setenforce 0

#sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
