Install MySQL under Linux installation source

Linux installation mysql--source installation

1. Assume that there are already mysql-5.5.10.tar.gz and cmake-2.8.4.tar.gz two source files

(1) Install CMake First (mysql5.5 is compiled by CMake later)

[[email protected] rhel5 Local] [[email protected] rhel5 Local] [[email protected] rhel5 cmake-2.8.4] [[email protected] rhel5 cmake-2.8.4] [[email protected] rhel5 cmake-2.8.4]

(2) Create a MySQL installation directory and database storage directory

[[email protected] rhel5~] [[email protected] rhel5~]

(3) Create MySQL users and user groups

[[email protected] rhel5~]groupadd Mysql[[email protected] rhel5~]useradd-r-g MySQL MySQL

(4) Installing MySQL

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

[[email protected] rhel5 Local] [[email protected] rhel5 Local] [Email protected] rhel5 mysql-5.5.10]-dcmake_install_prefix=/usr/local/mysql-dmysql_datadir=/usr/local/mysql/ Data-ddefault_charset=utf8-ddefault_collation=utf8_general_ci

-dextra_charsets=all-denabled_local_infile=1[[email protected] rhel5 mysql-5.5.10][[email protected] Rhel5 MYSQL-5.5.10]

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

Parameter description:

-dcmake_install_prefix=/usr/local/mysql//installation directory

-dinstall_datadir=/usr/local/mysql/data//Database storage directory

-ddefault_charset=utf8//using UTF8 characters

-DDEFAULT_COLLATION=UTF8_GENERAL_CI//Check character

-dextra_charsets=all//Install all extended character sets

-denabled_local_infile=1//Allow import of data from local

Precautions:

When you recompile, you need to clear the old object file and cache information.

# Make Clean

# rm-f CMakeCache.txt

# RM-RF/ETC/MY.CNF

2. Configuration

(1) Set directory permissions

[[email protected] rhel5~] [[email protected] rhel5 MySQL] [[email protected] rhel5 MySQL]

(2)

[[email protected] RHEL5 mysql]# CP support-files/my-medium.cnf/etc/my.cnf//Add MySQL startup service to system service

(3) Create a table for the system database

[[email protected] rhel5 MySQL] [[email protected] rhel5 MySQL]

(4) Setting environment variables

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

[[email protected] rhel5~] in path=:/bin add parameter: Path=:/bin:/usr/local/mysql/bin:/usr/local/mysql/lib[[email protected] Rhel5~]

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

(5) manually start MySQL

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

[[email protected] rhel5~] [[email protected] rhel5 MySQL] startup log is written under this file:/usr/local/mysql/data/localhost.err shutdown mysql service [[email protected] rhel5 MySQL ]

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

(6) Another simple way to start MySQL (MySQL has been added to the system service)

[[email protected] rhel5~] [[email protected] rhel5~] [[email protected] rhel5~]

If the above command appears: Mysql.server Unrecognized service

It is possible that MySQL has not been added to the system service, which is added in another way:

[[email protected] RHEL5 mysql]# CP support-files/mysql.server/etc/init.d/mysql//Add MySQL startup service to system service

Note: The main is to copy Mysql.server to/etc/init.d, named MySQL. In some systems, Mysql.server is in/usr/local/mysql/share/mysql/mysql.server, and in this system, mysql.server in/usr/local/mysql/ The Support-files/mysql.server.

Then use #service MySQL start to start MySQL.

(7) Change the password of the root user of MySQL and open the remote connection

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

[[email protected] rhel5~]mysql>use Mysql;mysql>desc user;mysql> GRANT all privileges on * * to [email protected]　　identified by; The ability to add remote connections for root. Mysql>update user Set Password = Password (' xxxxxx ') where user= ' root '; mysql>select host,user,password from User whe Re user= ' root '; Mysql>flush Privileges;mysql>exit re-login: Mysql-u root-p If you are not able to connect remotely, turn off the firewall [[email protected] rhel5~]

650) this.width=650; "src="%5c "alt=" \ "copy code \" "/>

Note: If you cannot connect remotely, error MySQL error number 1130, then add the following statement to try:

Mysql>grant all privileges on * * to ' root ' @ '% ' identified by ' ****** ' with GRANT OPTION;
