2, upload jdk to Linux

3, install the JDK run required plug-in yum install glibc.i686 (optional)

4, unzip the JDK to/usr/local under TAR–XVF jdk-7u71-linux-i586.tar.gz–c/usr/local

5, configure the JDK environment variable, open the/etc/profile configuration file, copy the configuration below

#set Java Environment

Java_home=/usr/local/jdk1.7.0_71

Classpath=.: $JAVA _home/lib.tools.jar

Path= $JAVA _home/bin: $PATH

Cd/usr/local

mkdir MySQL

TAR-XVF mysql-5.6.22-1.el6.i686.rpm-bundle.tar-c/usr/local/mysql

5, install MySQL under/usr/local/mysql

Install server side: RPM-IVH mysql-server-5.6.22-1.el6.i686.rpm

Install client: RPM-IVH mysql-client-5.6.22-1.el6.i686.rpm

An error occurred after adding:--nodeps--force

6, add MySQL to the system service and set the boot up
