MySQL安装与使用_MySQL
一、什麽是 MySQL
MySQL (发音为 "My Ess Que Ell")是 Tcx 公司开发的一个多人使用、多执行绪的 SQL 资料库 Server。MySQL 主要的目标在快速、稳定和容易使用。
MySQL 可在此 http://www.mysql.net/ 取得。
二、MySQL 的安装
本文所使用的 MySQL 版本为 mysql-3.22.27.tar.gz(原始码档),作业环境为 RedHat6.0 +CLE0.8 。
MySQL 预设情况下会安装至 /usr/local 目录下,不过为了日後移除方便,建议将 mysql 独立安装在 /usr/local/mysql 目录。底下为安装 MySQL 的步骤:
取得 mysql-3.22.27.tar.gz 後, 於 /usr/local 目录下解开:
# cd /usr/local
# tar zxvf mysql-3.22.27.tar.gz
# cd mysql-3.22.27
设定 configure 安装选项,选择安装目录 (prefix)以及支援中文 Big5 码(with-charset=big5):
# ./configure --prefix=/usr/local/mysql
#--with-charset=big5
开始编译并安装:
# make
# make install
# scripts/mysql_install_db
最後一个步骤是用来产生 MySQL grant tables(会建立一个 mysql 资料库和一些 tables,用来管理使用 MySQL 的授权资讯,也就是使用者有哪些使用资料库的权限)。
三、启动、停止 MySQL
要启动 MySQL 的方法:(以本文将 MySQL 安装在 /usr/local/mysql 为例)
# /usr/local/mysql/share/mysql.server start
注意在第一次执行前,须将 mysql.server 设成可执行(chmod 744 mysql.server),另外可将这行指令加在 /etc/rc.d/rc.local 档中,让 MySQL 在开机时自动启动。
要停止 MySQL 的方法:
# /usr/local/mysql/bin/mysqladmin shutdown
如果你为 MySQL Administrator root 帐号(非作业系统的 root)设了密码,要停止 MySQL 则必须像下列这样做,MySQL 会询问你 root 的密码後才会执行 shutdown 的工作:
# /usr/local/mysql/bin/mysqladmin -u root -p shutdown
