mysql二进制非root用户安装后启动mysqld的路径不对的问题
一、非root用户安装二进制mysql分发版
创建用户
>useradd fc
>passwd fc
enter password:
…
以fc登录，上传二进制mysql版本，我的是mysql 32位的mysql-5.1.57-linux-i686-glibc23.tar.gz
解压后，创建权限表
]$ scripts/mysql_install_db –basedir=/home/fc/app/mysql –datadir=/home/fc/app/mysql/data/3307 –user=fc
(注意：后面的参数一定要指定 ，另外最好是 scripts/mysql_install_db 这样一起运行，官方文档也是这样，免得出错，后面就有这个原因导致启动出错的)
权限表也初始化完了，然后就是指定配置文件my.cnf 我放在$HOME目录下：
# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients

好了，一切都准备好了，可以启动了
二、启动mysqld进程
进入basedir目录fc/app/mysql
mysql]$ cd bin
