Installation steps of MySQL5.1 (|) in Linux environment

1. MySQL installation-free version / binary plate software (no compilation)

File format: MYSQL-VERSION-OS.tar.gz

2. Create a MySQL group, establish MySQL users and join the group

(the syntax of groupadd and useradd may be slightly different in different versions of Unix. )

# groupadd mysql

# useradd-g mysql mysql

3. Enter the directory / usr/local, extract the free installation version, and set up a soft link named mysql in this directory.

# cd / usr/local

# gunzip

< /path/to/MYSQL-VERSION-OS.tar.gz | tar xvf - (该命令会在本目录下创建一个名为MYSQL-VERSION-OS的新目录。) (使用GNU tar，则不再需要gunzip。你可以直接用下面的命令来解包和提取分发： #>

Tar zxvf / path/to/mysql-VERSION-OS.tar.gz)

# ln-s MYSQL-VERSION-OS mysql

4. Add MySQL configuration file

If you want to set an options file, use one of the support-files directories as a template. There are four template files in this directory, which are customized according to the memory of different machines.

# cp support-files/my-medium.cnf / etc/my.cnf

(maybe you need to run these commands with the root user.)

5. Set directory access permissions, create MySQL authorization table initialization with mysql_install_db, and set mysql,root account access permissions

# cd mysql

# chown-R mysql.

# chgrp-R mysql.

# scripts/mysql_install_db-user=mysql

# chown-R root.

# chown-R mysql data

(pay attention to the "." symbols in the above command.)

6. Run MySQL

# bin/mysqld_safe-user=mysql &

(if there is no problem, there should be a prompt like this:

[1] 42264

# Starting mysqld daemon with databases from / usr/local/mysql/var

If there is a statement like mysql ended, which means that Mysql is not starting properly, you can find the problem in log. The Log file is usually configured in / etc/my.cnf.

Most of the problems are caused by incorrect permission settings. )

7. Set the root password. The default installation password is empty. You need to change the password for security.

# / usr/local/mysql/bin/mysqladmin-uroot password yourpassword

8. Copy a script in the compilation directory and set it to boot automatically.

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

# chmod 700 / etc/init.d/mysqld

# chkconfig-add mysqld

# chkconfig-level 345 mysqld on

9. Start the mysqld service

# service mysqld start

10. Check whether port 3306 is open. Pay attention to opening the port in the firewall

# netstat-atln

Overview of basic commands for installation-free / binary plate installation:

Shell > groupadd mysql

Shell > useradd-g mysql mysql

Shell > cd / usr/local

Shell > gunzip

< /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf - shell>

Ln-s FULL-PATH-TO-MYSQL-VERSION-OS mysql

Shell > cd mysql

Shell > chown-R mysql.

Shell > chgrp-R mysql.

Shell > scripts/mysql_install_db-user=mysql

Shell > chown-R root.

Shell > chown-R mysql data

Shell > bin/mysqld_safe-user=mysql &
