总结下mysql rpm安装的方式，与一些错误
环境
[root@host2 ~]# uname -a
Linux host2 2.6.32-504.3.3.el6.x86_64 #1 SMP Wed Dec 17 01:55:02 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
[root@host2 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
1,检查是否安装
[root@host2 ~]# rpm -qa | grep --color mysqlMySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle.tar
2,删除已安装
[root@host2 ~]# rpm -e mysql-libs-5.1.71-1.el6.x86_64 --nodeps
[root@host2 ~]#
3,查验，这样删还是会留下一些东西
[root@host2 ~]# find / -name mysql
[root@host2 ~]# find / -name *mysql*
/etc/selinux/targeted/modules/active/modules/mysql.pp
/usr/lib/python2.6/site-packages/sos/plugins/mysql.pyc
/usr/lib/python2.6/site-packages/sos/plugins/mysql.pyo

保证下面安装顺利,最好是将这些文件都删除
4,查验有否mysql用户和组
[root@host2 ~]# nl /etc/group | grep mysql
[root@host2 ~]# nl /etc/shadow | grep mysql
5,解包
[root@host2 mysql_rpm]# tar -xvf MySQL-5.6.22-1.linux_glibc2.5.x86_64.rpm-bundle.tar
MySQL-shared-compat-5.6.22-1.linux_glibc2.5.x86_64.rpm #RHEL兼容包

MySQL-embedded-5.6.22-1.linux_glibc2.5.x86_64.rpm #MySQL的嵌入式程序
6,安装，会自动初始化数据库

You will find that password in ‘/root/.mysql_secret‘. You must change that password on your first connect, no other statement but ‘SET PASSWORD‘ will be accepted. See the manual for the semantics of the ‘password expired‘ flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database. This is strongly recommended for production servers. See the manual for more instructions. 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 /usr/my.cnf and will be used by default by the server when you start it. You may edit this file to change server settings
7,RPM安装方式文件分布

8,copy配置文件
# 没有这一步也可以按内置参数
[root@host2 mysql_rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
9,启动mysql
[root@host2 mysql_rpm]# service mysql status
MySQL is not running [FAILED]
[root@host2 mysql_rpm]# service mysql start
Starting MySQL.. [ OK ]
10,检查进程
[root@host2 mysql_rpm]# netstat -anpl | grep mysql

unix 2 [ ACC ] STREAM LISTENING 76015 5924/mysqld /var/lib/mysql/mysql.sock
11,安装客户端
[root@host2 mysql_rpm]# rpm -ivh MySQL-client-5.6.22-1.linux_glibc2.5.x86_64.rpm
Preparing... ########################################### [100%]

12,连到mysql并修改
[root@host2 mysql_rpm]# nl /root/.mysql_secret

在启动过程中，曾遇到这个错误（The server quit without updating PID file），相信许多人应该也遇到过，做下总结：
原因：在MySQL的datadir数据目录下没有pid文件或者未被授权
解决方式：
（1）一定要给譬如/data/mysql授权
chown -R mysql:mysql /data/mysql
（2）如果授权了不好使，你可以自己在/data/mysql下建立一个以主机名命名的pid，如我的主机名是centos-6.3
你可以cd /data/mysql && touch centos-6.3.pid
在里面随意写一个进程中没有的pid号
（3）如果还是不行，你就需要看看配置文件/etc/my.cnf里面的配置了，将port、datadir、basedir、 socket前的#去掉
（4）另外的处理方法还有可能是下面的原因导致
1>可能是第二次在机器上安装mysql，有残余数据影响了服务的启动。
解决方法：去mysql的数据目录/data看看，如果存在mysql-bin.index，就赶快把它删除掉吧，它就是罪魁祸首了
2>mysql在启动时没有指定配置文件时会使用/etc/my.cnf配置文件，请打开这个文件查看在[mysqld]节下有没有指定数据目录(datadir)。
解决方法：请在[mysqld]下设置这一行：datadir = /usr/local/mysql/data
3>skip-federated字段问题
解决方法：检查一下/etc/my.cnf文件中有没有没被注释掉的skip-federated字段，如果有就立即注释掉吧。
4>selinux惹的祸，如果是centos系统，默认会开启selinux（今天遇到的错误就是这个）
解决方法：关闭它，打开/etc/selinux/config，把SELINUX=enforcing改为SELINUX=disabled后存盘退出重启机器试试。
