MySQL 5.5 配置
==================================================
1.MySQL目录授权
chown -R mysql:mysql /usr/local/mysql-5.5/
2.拷贝MySQL配置文件
cp -a /usr/local/mysql-5.5/support-files/my-medium.cnf /etc/my.cnf
cp -a /usr/local/mysql-5.5/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
3.初始化MySQL
cd /usr/local/mysql-5.5/scripts/
/usr/local/mysql-5.5/scripts/mysql_install_db \
--basedir=/usr/local/mysql-5.5/ \
--datadir=/usr/local/mysql-5.5/data/ \
--user=mysql
4.启动MySQL
/etc/init.d/mysqld start
/usr/local/mysql-5.5/bin/mysqld_safe --user=mysql &
5.配置环境变量
echo 'export PATH=/usr/local/mysql-5.5/bin:$PATH' >> /etc/profile
source /etc/profile
6.设置登陆密码
/usr/local/mysql-5.5/bin/mysql_secure_installation
7.设置MySQL开机启动
chkconfig mysqld on
chkconfig --list mysqld
echo "/usr/local/mysql/bin/mysqld_safe --user=mysql &" >> /etc/rc.local
7.登陆MySQL测试
/usr/local/mysql-5.5/bin/mysql -uroot -p

[问题描述]
描述：MySQL 第一次初始化后无法启动
错误代码：Starting MySQL..The server quit without updating PID file ([FAILED]al/mysql-5.5/data/www.pid).
