linux下安装mysql
#tar zxvf mysql-4.1.18.tar.gz
#cd mysql-4.1.18
#./configure --prefix=/usr/local/mysql --with-charset=gb2312 --with-extra-charsets=all
#make
#make install
#make clean
#cp /usr/local/mysql/share/mysql/my-huge.cnf /etc/my.cnf
#groupadd mysql
#useradd -g mysql mysql
#cd /usr/local/mysql
#bin/mysql_install_db --user=mysql
#建立基本，必须指明为mysql用户,出现如下：
Preparing db table
Preparing host table
Preparing user table
Preparing func table
Preparing tables_priv table
Preparing columns_priv table
Installing all prepared tables
Unknown suffix '@' used for variable 'port' (value '@MYSQL_TCP_PORT@')
080425 4:38:40 /usr/local/mysql/libexec/mysqld: Error while setting value '@MYSQL_TCP_PORT@' to 'port'
Installation of grant tables failed!
Examine the logs in /usr/local/mysql/var for more information.
You can also try to start the mysqld daemon with:
/usr/local/mysql/libexec/mysqld --skip-grant &
You can use the command line tool
/usr/local/mysql/bin/mysql to connect to the mysql
database and look at the grant tables:
shell> /usr/local/mysql/bin/mysql -u root mysql
mysql> show tables
Try 'mysqld --help' if you have problems with paths. Using --log
gives you a log in /usr/local/mysql/var that may be helpful.

Please consult the MySQL manual section: 'Problems running mysql_install_db',
and the manual section that describes problems on your OS.
Another information source is the MySQL email archive.
Please check all of the above before mailing us!
And if you do mail us, you MUST use the /usr/local/mysql/bin/mysqlbug script!
启动
# bin/mysqld_safe --user=mysql & #出现如下提示：
[1] 23095
[root@localhost mysql]# Starting mysqld daemon with databases from /usr/local/mysql/var
###这样就停在这边，就是正常启动。如果想确认用下面命令
# ps -aux |grep mysql
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.3/FAQ

#bin/mysqld_safe &或/usr/local/mysql/share/mysql/mysql.server start 启动mysql
#/usr/local/mysql/share/mysql/mysql.server stop 停止mysql
#ps -aux|grep mysql查看进程
#kill id号 ----这是杀mysql进程的，id号是在查看mysql进程里面看的到。
我们来修改一下mysql的启动的方式，让它以系统守护进程的方式开户服务
#cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysqld 这样下次就可以用/etc/init.d/mysqld start启动了
# bin/mysql -uroot -p
Enter password:
ERROR 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
这个是mysql没启动
# /etc/init.d/mysqld start (或/usr/local/mysql/mysql/share/mysql.server start这样启动)
# bin/mysql -uroot -p
