Centos5.5中安装Mysql5.5过程分享

FATAL ERROR: Could not find./bin/my_print_defaults
If you compiled from source, you need torun 'make install' to
copy the software into the correct locationready for operation.
If you are using a binary release, you musteither be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.

解决方法：

[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

再启动mysql

[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql

注册mysql服务，开机自动启动

1.设置mysql配置文件到/etc目录

[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf 

2.设置mysql开机自启

[root@local ~]# cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@local ~]# chmod +x /etc/init.d/mysql
[root@local ~]# /sbin/chkconfig --add mysql

3.启动mysql服务

[root@local ~]# service mysql start 

测试mysql是否安装成功

[root@local ~]# /usr/local/mysql/bin/mysql -u root -p
