创建挂载点：

[root@1inux ~]# mkdir /data
[root@1inux ~]# mount -a
[root@1inux ~]# mount
.....
/dev/mapper/myvg-mydata on /data type ext4 (rw)

在/data目录下创建子目录mydata专门用于存放数据库

[root@1inux ~]# cd /data/
[root@1inux data]# mkdir mydata
[root@1inux data]# ls

初始化mysql


[root@1inux mysql]# scripts/mysql_install_db --help  查看帮助

  --datadir=path         mysql数据存放的路径
  --defaults-file=name  自定义mysql配置文件路径
  --user=user_name     以哪个用户的身份运行
  --skip-name-resolve  禁止使用DNS做名称反解
  --basedir=path       The path to the MariaDB installation directory.
  --builddir=path      If using --srcdir with out-of-directory builds, you
                       will need to set this to the location of the build
                       directory where built files reside.
  --cross-bootstrap    For internal use.  Used when building the MariaDB system
                       tables on a different host than the target.
  --defaults-extra-file=name
                       Read this file after the global files are read.
  --force              Causes mysql_install_db to run even if DNS does not
                       work.  In that case, grant table entries that normally
                       use hostnames will use IP addresses.
  --help               Display this help and exit.                     
  --ldata=path         The path to the MariaDB data directory. Same as
                       --datadir.
  --no-defaults        Don't read default options from any option file.
  --defaults-file=path Read only this configuration file.
  --rpm                For internal use.  This option is used by RPM files
                       during the MariaDB installation process.
  --srcdir=path        The path to the MariaDB source directory.  This option
                       uses the compiled binaries and support files within the
                       source tree, useful for if you don't want to install
                       MariaDB yet and just want to create the system tables.

[root@1inux mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mydata

[root@1inux mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mydata
WARNING: The host '1inux' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MariaDB version. The MariaDB daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MariaDB privileges !
Installing MariaDB/MySQL system tables in '/data/mydata' ...

Filling help tables...
150501 20:48:22 [Warning] 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release.
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 MariaDB 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 1inux 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 MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='/data/mydata'

You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl

Please report any problems at http://mariadb.org/jira

注：mysql数据库中的每个数据库是以其名字命名的目录


编辑配置文件：
[root@1inux mysql]# vim /etc/mysql/my.cnf

在thread_concurrency = 8 下面添加如下两行：
datadir = /data/mydata        //如果不指定，默认会认为其数据存储目录是安装目录下的data目录
innodb_file_per_table = on


配置服务脚本：
    
[root@1inux mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@1inux mysql]# chmod +x /etc/rc.d/init.d/mysqld

[root@1inux mysql]#

MANPATH /usr/local/mysql/man

输出mysql的头文件至系统头文件路径/usr/include：

[root@1inux mysql]# ln -sv /usr/local/mysql/include/ /usr/include/mysql
`/usr/include/mysql' -> `/usr/local/mysql/include/'
[root@1inux mysql]#


输出mysql的库文件给系统库查找路径：

# echo '/usr/local/mysql/lib' > /etc/ld.so.conf.d/mysql.conf


而后让系统重新载入系统库：
# ldconfig
