1. View information about the operating system.
[root@linuxidc ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@linuxidc ~]# uname -a
Linux linuxidc 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
2. Create the directory where the rpm package needs to be downloaded.
1 [root@linuxidc ~]# mkdir -p /taokey /tools
3. Check whether there is an rpm package of mysql that comes with the system. If so, you need to delete the old rpm package that comes with it.
[root@linuxidc ~]# rpm -qa | grep mysql
mysql-libs-5.1.71-1.el6.x86_64
[root@linuxidc ~]# yum -y remove mysql-libs-5.1*
[root@linuxidc ~]# rpm -qa | grep mysql
[root@linuxidc ~]#
4. Download and install the rpm package required for MySQL-5.6.21 on the MySQL official website.
Three rpm packages need to be downloaded:
MySQL-client-5.6.21-1.rhel5.x86_64.rpm
MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
MySQL-server-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc ~]# cd/taokey/tools/
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm
5. After downloading, install the three rpm packages.
[root@linuxidc tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
error: Failed dependencies:
libaio.so.1()(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
An error is reported when installing MySQL-server, because libaio is not installed, and the system lacks the libaio.so package. Install the libaio.so package in yum below.
[root@linuxidc tools]# yum install -y libaio
[root@linuxidc tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
[root@linuxidc tools]# rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm
