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
