在redhat下安装mysql5.1.30.

先从网上下载mysql5.1.x版本的tar.gz的包。下面是安装过程：

chmod 755 mysql-5.1.30.tar.gz

tar -zxvf mysql-5.1.30.tar.gz -C /usr/src/
cd /usr/src/mysql-5.1.30
./configure --prefix=/usr/local/mysql --with-charset=gbk --localstatedir=/usr/local/mysql/data
make
make install
groupadd mysql
useradd mysql -g mysql
cd /usr/local/mysql/bin
./mysql_install_db --user=mysql

cd /usr/local/mysql
chown -R root .
chgrp -R mysql .
cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysqld

修改配置文件：

change /etc/my.cnf to below:
*****************start************
[mysqld]                                                               
datadir=/var/lib/mysql                                                 
socket=/var/lib/mysql/mysql.sock                                       
user=mysql                                                             
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).       
old_passwords=1                                                        
                                                                       
[mysqld_safe]                                                          
log-error=/var/log/mysqld.log                                          
pid-file=/var/run/mysqld/mysqld.pid                                    
socket=/var/lib/mysql/mysql.sock   
                                    
[mysqladmin]                                                           
socket=/var/lib/mysql/mysql.sock   
                                    
[mysql]                                                                
socket=/var/lib/mysql/mysql.sock        
*****************end************     

cd /etc/init.d/                                            
# chmod 777 mysqld                 
# chkconfig mysqld               
# chkconfig --add mysqld         
# chkconfig --level 345 mysqld on
# service mysqld start

配置mysql在远程的本机都能登陆：

# cp /usr/local/mysql/bin/* /usr/bin/    
# netstat -tnl |grep 3306
# /usr/local/mysql/bin/mysqladmin -uroot password admin

mysql -uroot -p #进入mysql     
#为了开发方便,可以让root用户具有远程访问的权限                                                       

mysql>use mysql;

mysql>update user set password=old_password('新密码');

mysql> flush privileges;
                                                         
mysql> grant all on *.* to root@'%' identified by 'admin';                   
 #grant 权限 on 数据库名.表名 to 用户@登录主机(%代表所有主机) identified by "用户密码";
                                                                        
mysql> flush privileges;      


ERROR 1042 (00000): Can't get hostname for your address解决方案

[root@sv245 mysql]# cp /opt/lampp/etc/my.cnf /etc/my.cnf
[root@sv245 mysql]# vi /etc/my.cnf
在配置文件中增加：
[mysqld]下增加下面一句话：
skip-name-resolve
[root@sv245 mysql]# service mysql restart

ok，连接成功：

注释：

#1：去掉mysql启动参数中的skip-name-resolve ，然后jdbc连接串用ip地址和主机名均可。

#2：如果保留启动参数skip-name-resolve 的话，在jdbc连接串中只能使用IP地址的方式连接数据库。
