Compile and install Mysql:

one。 Set up a data catalog. (default is under the mysql installation directory)

1. Create a directory / mydata/data

[note: any directory created under the mysql data directory will be recognized as a database]

two。 Establish a separate partition / dev/sdaX (based on the actual situation, it is recommended to use LVM logical volumes)

3. Mount the newly created partition to / mydata

4. Edit boot auto mount

Vim / etc/fstab

Add something like the following line:

Device mount point file system defaults 0 0

two。 Create user: the user used by the Mysql operation

1.groupadd-g 3306 mysql

2.useradd-u 3306-g mysql-M-s / sbin/nologin mysql

three。 Give mysql users all permissions on the data directory

Chown-R mysql:mysql / mydata

four。 Decompress configuration Mysql

1.tar xf mysql-5.5.15-linux2.6-i686.tar.gz-C / usr/local

2.cd / usr/local

3.ln-sv mysql-5.5.15-linux2.6-i686 mysql

4.cd mysql

5.chown-R mysql:mysql.

Initialize Mysql:

6.scripts/mysql_install_db-user=mysql-datadir=/mydata/data

7.chown-R root.

five。 Configuration service startup:

Prepare the startup script:

8.cp support-files/mysql.server / etc/init.d/mysqld

Join the service queue

9.chkconfig-add mysqld

Set the boot to start automatically

10.chkconfig mysqld on

Copy the configuration file:

11.cp support-files/my-large.cnf / etc/my.cnf

12.vim / etc/my.cnf

Add the following under the [mysqld] field

Datadir = / mydata/data

Change thread_concurrency = 8 to thread_concurrency = 2

Start the service:

13.service mysqld start

[note: if startup fails, please check the file ending with ".err" in the "data directory"]

six。 Prepare header files, library files, PATH variables (not required, but files that depend on mysql will go to the default directory to find relevant files)

# Library files:

Vim / etc/ld.so.conf.d/mysql.conf

Add: / usr/local/mysql/lib-- > Save exit

Ldconfig (- v displays the execution result)

# header file:

Ln-sv / usr/local/mysql/include / usr/include/mysql

# PATH

Vim / etc/profile

Add: PATH=$PATH:/usr/local/mysql/bin (it is recommended to add to the "export" line)

Source / etc/profile

# MAN (it doesn't matter if you don't want to configure it)

Vim / etc/man.config

Add: MANPATH / usr/local/mysql/man
