MYSQL Study案例之--RedHat EL55源码安装Mysql-5.6
系统环境：
操作系统：RedHat EL55
DB Soft： Mysql 5.6.4-m7
1、系统环境
[root@rh55 Packages]# uname -a Linux rh6 2.6.18-194.el5.xen #1 SMP Tue Jan 29 11:47:41 EST 2013 i386 i686 GNU/Linux [root@rh55 Packages]#
2、安装cmake软件
对于RedHat EL55系统，安装光盘不包含cmake文件，需要从网上下载安装
下载地址：http://www.cmake.org/download/
[root@rh55 soft]# ls
cmake-3.2.3 cmake-3.2.3.tar.gz
[root@rh55 soft]# tar zxvf cmake-3.2.3.tar.gz

To do so, start the server, then issue the following commands: ./bin/mysqladmin -u root password ‘new-password‘ ./bin/mysqladmin -u root -h rh6 password ‘new-password‘ Alternatively you can run: ./bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; ./bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd ./mysql-test ; perl mysql-test-run.pl Please report any problems with the ./bin/mysqlbug script!

5、查看mysql配置文件
[root@rh55 mysql]# cat /etc/my.cnf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
6、启动mysqld服务
