所有这些操作在Linux系统下进行,需要root权限
安装开始：
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> gunzip < mysql-VERSION.tar.gz | tar -xvf -
shell> cd mysql-VERSION
shell> ./configure --prefix=/usr/local/mysql --with-charset=gb2312
shell> make
shell> make install
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> cd /usr/local/mysql
shell> bin/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql var
shell> chgrp -R mysql .
shell> bin/mysqld_safe --user=mysql &
(用mysql用户启动很重要。)
shell> bin/mysql -uroot -p
(输入密码，默认密码为空，直接回车即可)
shell> Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
如果出现上面的提示，说明mysql服务没有正常启动,因为mysql服务启动的话,会自动生成mysql.sock文件
shell> killall mysql
杀掉所有mysql进程，重新启动
shell> bin/mysql_install_db --user=mysql
重新启动
shell> bin/mysql -uroot -p
