CentOS6.3 install MySQL5.5

1. Download MySQL
Version I downloaded: mysql-5.5.22.tar.gz

2. uninstall MySQL that comes with CentOS before installation
[Root @ localhost ~] # Yum remove mysql

3. Compile and install Cmake
Download cmake source package: http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz

Move from shared directory to usr directory
[Root @ localhost ~] # Mv/mnt/hgfs/Share-CentOS/cmake-2.8.4.tar.gz/usr/cmake-2.8.4.tar.gz
[Root @ localhost ~] # Cd/usr

Decompress and install cmake
[Root @ localhost usr] # tar xzvf cmake-2.8.4.tar.gz
[Root @ localhost usr] # cd cmake-2.8.4
[Root @ localhost cmake-2.8.4] #./bootstrap

4. start installing MySQL
Add MySQL users and user groups
[Root @ localhost ~] # Groupadd mysql
[Root @ localhost ~] # Useradd-g mysql

Migrate the MySQL source code package from the shared folder to/usr and decompress it.
[Root @ localhost ~] Mv/mnt/hgfs/Share/CentOS/mysql-5.5.22.tar.gz/usr/mysql-5.5.22.tar.gz
[Root @ localhost usr] # tar xzvf mysql-5.5.22.tar.gz
[Root @ localhost usr] # cd mysql-5.5.22

Run Cmake
[Root @ localhost mysql-5.5.22] # cmake.

Start compilation and Installation
[Root @ localhost mysql-5.5.22] # make & make install

Go to the installation directory, change the ownership of the binary program to root, and change the description of the data directory to mysql user to update the authorization table.
[Root @ localhost mysql-5.5.22] # cd/usr/local/mysql/
[Root @ localhost mysql] # chown-R root.
[Root @ localhost mysql] # chown-R mysql.
[Root @ localhost mysql] # chgrp-R mysql.
[Root @ localhost mysql] # scripts/mysql_install_db -- user = mysql

Start MySQL safely (the default password is blank)
[Root @ localhost mysql] #./bin/mysqld_safe -- user = mysql &

Error:
