#使用默认配置文件 cd /usr/local/mysql/support-files cp my-default.cnf /etc/my .cnf #修改配置文件,添加下面的内容 #socket适用于,通信的,一定要添加 #socket的位置和cmake时mysql的-DMYSQL_UNIX_ADDR=/tmp/mysql.sock的路径,socket的路径地址要和前面的地址一样(不然mysql服务不能正常启动.) basedir = /usr/local/mysql datadir = /usr/local/mysql/data pid- file = /usr/local/mysql/data/mysql .pid user = mysql socket= /tmp/mysql .sock |
5、将mysql服务,添加到系统服务里面,并设置开启自启动

cd /usr/local/mysql/support-files #注册服务 cp mysql.server /etc/rc .d /init .d /mysql #让chkconfig管理mysql服务 chkconfig --add mysql #开机启动 chkconfig mysql on |

service mysql start #验证mysql启动成功 netstat -ant | grep 3306 |
7、配置mysql用户,修改root密码
Mysql启动成功后,root默认没有密码,我们需要设置root密码。
设置root密码之前,先设置PATH路径,以便能直接调用/usr/local/mysql/bin中的mysql等命令.
修改/etc/profile文件,在文件末尾加入
1
2
|
PATH= /usr/local/mysql/bin :$PATH export PATH |
关闭文件,运行下面的命令,让配置立即生效
source /etc/profile

|
#将下面的'password'改成自己的密码 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root' @ '%' IDENTIFIED BY 'password' WITH GRANT OPTION; mysql> flush privileges; |
9、关闭防火墙,防止远程连接失败
1)重启后生效
开启: chkconfig iptables on
关闭: chkconfig iptables off
2)立即生效
开启: service iptables start
关闭: service iptables stop
3)开放3306端口

vi /etc/sysconfig/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT service iptables restart |

11、可能出现的错误
问题1:Starting MySQL..The server quit without updating PID file ([FAILED]/mysql/Server03.mylinux.com.pid).
解决:
修改/etc/my.cnf 添加socket的配置
问题2:ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
解决:
新建一个链接或在mysql中加入-S参数,直接指出mysql.sock位置。
