1. Install cmake-2.8.10.2.tar.gz

Enter shell as root user

# tar-zxvf cmake-2.8.10.2.tar.gz

# cd cmake-2.8.10.2

#. / configure

# make (cannot make, detect gcc compilation environment)

# make install

-

2. Install ncurses-5.9.tar.gz

# tar-zxvf ncurses-5.9.tar.gz

# cd ncurses-5.9

# mkdir / usr/local/ncurses-5.9/

#. / configure-prefix=/usr/local/ncurses-5.9/

# make

# make install

-

3. Install mysql-5.5.28.tar.gz

# tar-zxvf mysql-5.5.28.tar.gz

# cd mysql-5.5.28

# mkdir-p / usr/local/mysql (create database installation directory)

# mkdir-p / usr/local/mysql/data (storing database)

# groupadd mysql

# useradd-r-g mysql mysql

Start compiling mysql source code

# cmake. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/-DMYSQL_DATADIR=/usr/local/mysql/data-DCURSES_INCLUDE_PATH=/usr/local/ncurses-5.9/include/-DCURSES_LIBRARY=/usr/local/ncurses-5.9/lib/libncurses.a

# make

# make install (mysql will be installed after this one is finished)

4. Configure MySQL

Set directory permissions

# cd / usr/local/mysql

# chown-R root:mysql. (set the owner owner of all files in the current directory to root and the group to which they belong to mysql)

# chown-R mysql:mysql data

# cp support-files/my-medium.cnf / etc/my.cnf (add mysql startup service to system service)

Create a table for the system database

# cd / usr/local/mysql

# scripts/mysql_install_db-user=mysql

Start mysql manually

# cd / usr/local/mysql

#. / bin/mysqld_safe-user=mysql &

# mysqladmin-u root-p shutdown (stop the MySQL service, where the root user of MySQL has not yet configured a password, so it is null. When you need to enter a password, just click the enter key.)

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

# cp support-files/mysql.server / etc/init.d/mysql (add mysql startup service to system service)

# service mysql.server start starts mysql service

# service mysql.server stop shuts down mysql service

# service mysql.server restart restart mysql service

Add mysql to the environment variable so that you can enter mysql by typing mysql in the shell environment.

# vi / etc/profile

Join at the end

Export MYSQL_HOME=/usr/local/mysql

Export PATH=$MYSQL_HOME/bin:$PATH

# wq save

# source / etc/profile refresh configuration file

After typing in mysql, you can see the mysql console interface.

Change the password of the root user of MySQL and open a remote connection

# mysql-u root mysql

Mysql > use mysql

Mysql > desc user

Mysql > GRANT ALL PRIVILEGES ON *. * TO root@ "%" IDENTIFIED BY "root"; (the ability to add remote connections to root.)

Mysql > update user set Password = password ('root') where User='root'; (set root user password to root, customizable)

Mysql > select Host,User,Password from user where User='root'

Mysql > flush privileges

Mysql > exit

Log in again: mysql-u root-proot

If a remote connection cannot be made, turn off the firewall

# / etc/rc.d/init.d/iptables stop
