RHEL6.2 全新安装MYSQL5.5.22

linux内核版本：

#uname -r
2.6.32-220.7.1.el6.centos.plus.x86_64

需要的软件：

cmake-2.8.5.tar.gz

mysql-5.5.22.tar.gz 

 

因为mysql5.5是通过cmake编译器进行编译所以安装mysql5.5时先安装cmake

#yum -y install  ncurses-devel  *gcc*  *make*
 

安装cmake：

wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz

#tar -zxvf  cmake-2.8.5.tar.gz

#cd cmake-2.8.5

#./bootstrap

#make && make install

 

安装mysql：

到官方网站下载mysql最新版本：

http://dev.mysql.com/downloads/

我这下载的是目前最新的

#tar -zxvf mysql-5.5.22.tar.gz 

#cd mysql-5.5.22

// 详细参数请参考：http://blog.wqgcool.com/?p=677

#cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql5\ 

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql5 \

-DEXTRA_CHARSETS=all

 

#make && make install

 

//如果要重新牌子请执行：

#rm -rf CMakeCache.txt

#make clean  all

配置mysql5：

# pwd

/usr/local/mysql5

#cp support-files/my-medium.cnf /etc/my.cnf 

//创建mysql配置文件

 

//开机启动

# pwd

/usr/local/mysql5

#cp support-files/mysql.server /etc/init.d/mysql

# chkconfig --add mysql

初始化数据库：

# chown -R mysql   /usr/local/mysql5/

#chown -R mysql:mysql  /usr/local/mysql5/data

#   /usr/local/mysql5/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql5 --datadir=/usr/local/mysql5/data 

//操作这一步可能会报错，所以在编译的时候最好少添加点参数。如过和我一样是菜鸟的话！

 

# service mysql start

# chkconfig mysql on

#ps -e | grep mysql

5722 pts/0    00:00:00 mysqld_safe

5974 pts/0    00:00:00 mysqld

 

设置mysql的PATH路径

#export PATH=$PATH:/usr/local/mysql5/bin/

#echo "PATH=$PATH:/usr/local/mysql5/bin/" >> /etc/profile

//永久生肖

 

登录mysql

#mysqladmin -u root password wdmysql

输入密码：

mysql> status；
