搞定linux上MySQL编程（一）：linux上源码安装MySQL - 数据库编程

1. 首先下载源码包：

ftp://ftp.jaist.ac.jp/pub/mysql/Downloads/MySQL-5.1/mysql-5.1.72.tar.gz

2. 使用如下命令检查系统中是否已安装mysql：

rpm -qa |  grep mysql

3.没有安装则解压安装包然后进入该目录：

cd mysql

分别依次执行如下操作：

./configure --prefix=/usr/local/mysql --with-charset=gbk
make
make install

4.添加MySQL配置文件

如果你想要设置一个选项文件，使用support-files目录中的一个作为模板。在这个目录中有4个模板文件，是根据不同机器的内存定制的。

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

5.设置开机自动启动

#cp support-files/mysql.server /etc/rc.d/init.d/mysqld
#chmod 755 /etc/init.d/mysqld
#chkconfig –-add mysqld
#chkconfig –-level 345 mysqld on

6.创建mysql权限表：

cd /usr/local/mysql
scripts/mysql_install_db --user=mysql

7.最后将安装目录的拥有者和所属组分别变更为root和mysql，命令为：

chown -R root
chgrp -R mysql

8.测试成功否？
第一次运行会弹出如下信息，说明安装成功：

#/etc/rc.d/init.d/mysqld start

Initializing MySQL database:? Installing MySQL system tables... 
OK 
Filling help tables... 
OK 
?
To start mysqld at boot time you have to copy 
support-files/mysql.server to the right place for your system 
?
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! 
To do so, start the server, then issue the following commands: 
?
/usr/bin/mysqladmin -u root password 'new-password' 
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password' 
?
Alternatively you can run: 
/usr/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 /usr ; /usr/bin/mysqld_safe & 
?
You can test the MySQL daemon with mysql-test-run.pl 
cd /usr/mysql-test ; perl mysql-test-run.pl 
?
Please report any problems with the /usr/bin/mysqlbug script! 
?

9.查看3306端口是否启动：

# netstat -altnp
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name  
tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN      6946/mysqld        
tcp        0      0 0.0.0.0:111                 0.0.0.0:*                   LISTEN      1892/rpcbind        
tcp        0      0 192.168.122.1:53            0.0.0.0:*                   LISTEN      2726/dnsmasq

10.为了安全，需要修改密码，默认为空：

mysqladmin -u root password shallnet

至此，可以在命令行上面使用新的密码登录mysql了。
