脚本自动安装单实例mysql

这个也是自己在学习了一段linux之后，自己写的一个一键安装mysql单实例。脚本目录大概是这样的，一下这个是我安装文件里面的目录，其实脚本我只是将安装过程用脚本写出来而已。个人感觉脚本里面的安装过程没有变化。不懂大家手动安装过程一不一样。 目前安装我的系统是CentOS release 5.6 32 Linux 2.6.18-238.el5。mysql软件：mysql-5.0.45.tar.gz 目前我也不是很清楚大家使用得比较广泛的版本是什么版本，应该没有接触过真正的实际案例。[PS:本人英文考试没有一次及格过，文中的英文语法错误应该是正常的，请大家忽略。]1)创建mysql用户2）编译、安装mysql--编译参数要正确，不带mysql版本3）拷贝配置文件和mysql4）创建数据库文件5）授权mysql用户访问 chown -R mysql.mysql /usrl/local/mysql6）配置全局路径7）初始化数据库8）启动mysql数据库

-----------------------------低调的分割线------------------------------------------------不懂为什么正常的安装完成之后，通过这个mysqld文件来进行启动，就是启动不起来。而如果是通过/usr/local/mysql/bin/mysqld_safe & 就是能够启动起来。这个不懂是什么原因。如果有知道，也请在评论中告诉我吧。另：mysqladmin -uroot password "修改的密码"
