给大家带来CentOS上MySQL数据库办事器设置***
如果您觉得本篇CentOSLinux教程讲得好,请记得点击右边漂浮的分享程序,把好文章分享给你的好朋友们!本次情况:CentOS体系,
mysql-server(版本忘了,由于是利用yum装置的)
历程以下(转载,依据自己装置具体请求,略加修正) :
在提到网站构架的时分,我们常常可以看到“LAMP”的说法,它就是“Linux+Apache+MySQL+PHP”。MySQL+PHP的协同乐成案例已良多了。好比外洋的PHPBB,VBB,国际的Discuz!服装论坛等等步伐,都是用PHP+MySQL完成的。和那些商务公用数据库比起来,MySQL的功效和范围大概被很多多少人说的减色一些,但关于我们团体来讲,它的功效已算是完整。并且,通过Discuz!官方服装论坛上同时在耳目数的数量,也能够证实MySQL的不乱性。
这里,先容一下CentOS下MySQL数据库办事器的构建***。
装置MySQL及相干组件
起首,装置MySQL。

Complete!设置MySQL
然后,设置MySQL。
#vi/etc/my.cnf ←编纂MySQL的设置文件
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
#Defaulttousingoldpasswordformatforcompatibilitywithmysql3.x
#clients(thoseusingthemysqlclient10compatibilitypackage).
old_passwords=1 ←找到这一行,在这一行的上面增加新的划定规矩,让MySQL的默许编码为UTF-8
default-character-set=utf8 ←增加这一行
然后在设置文件的文尾填加以下语句:
default-character-set=utf8启动MySQL办事
启动MySQL,并让MySQL在体系从头启动后随体系主动启动。
#chkconfigmysqldon ←设置MySQL办事随体系启动自启动
#chkconfig--listmysqld ←确认MySQL自启动
mysqld0:off1:off2:on3:on4:on5:on6:off ←假如2--5为on的形态就OK
#/etc/rc.d/init.d/mysqldstart ←启动MySQL办事
InitializingMySQLdatabase: [OK]
StartingMySQL: [OK]MySQL初始情况设定
为MySQL的root用户设置暗码
MySQL在方才被装置的时分,它的root用户是没有被设置暗码的。起首来设置MySQL的root暗码。
#mysql-uroot ←用root用户登录MySQL办事器
WelcometotheMySQLmonitor.Commandsendwith;org.
YourMySQLconnectionidis2toserverversion:4.1.20Typehelp;orhforhelp.Typectoclearthebuffer.
mysql>selectuser,host,passwordfrommysql.user; ←检察用户信息
+------+------------------------------+---------------+
|user|host |password |
+------+------------------------------+---------------+
|root|localhost | | ←root暗码为空
|root|sample.centospub.com | | ←root暗码为空
| |sample.centospub.com| |
| |localhost | |
+------+------------------------------+---------------+
4rowsinset(0.00sec)
mysql>setpasswordforroot@localhost=password(在这里填进root暗码); ←设置root暗码

mysql>setpasswordforroot@sample.centospub.com=password(在这里填进root暗码); ←设置root暗码
QueryOK,0rowsaffected(0.01sec)
mysql>selectuser,host,passwordfrommysql.user; ←检察用户信息
+------+--------------------------------+--------------------------+
|user|host |password |

| |sample.centospub.com | |
| |localhost | |
+------+--------------------------------+--------------------------+
4rowsinset(0.01sec)
mysql>exit ←加入MySQL办事器
Bye
然后,测试一下root暗码有无失效。
#mysql-uroot ←经由过程空暗码用root登录
ERROR1045(28000):Accessdeniedforuserroot@localhost(usingpassword:NO) ←呈现此毛病信息申明暗码设置乐成
#mysql-uroot-hsample.centospub.com ←经由过程空暗码用root登录

Typehelp;orhforhelp.Typectoclearthebuffer.
mysql>exit ←加入MySQL办事器
Bye
删除匿名用户
在MySQL方才被装置后,存在用户名、暗码为空的用户。这使得数据库办事器有没有需暗码被登录的大概性。为打消隐患,将匿名用户删除。
#mysql-uroot-p ←经由过程暗码用root登录
Enterpassword: ←在这里输出暗码
WelcometotheMySQLmonitor.Commandsendwith;org.

|root|localhost |
|root|sample.centospub.com|
+------+----------------------------+
2rowsinset(0.00sec)
mysql>exit ←加入MySQL办事器
Bye
删除测试用数据库
在MySQL被装置后,存在名为test的空数据库,将它删除。这里要注重的是,体系默许的另有一个名为mysql的数据库,它用于体系办理,以是请不要删除。
#mysql-uroot-p ←经由过程暗码用root登录
Enterpassword: ←在这里输出暗码
WelcometotheMySQLmonitor.Commandsendwith;org.
YourMySQLconnectionidis8toserverversion:4.1.20Typehelp;orhforhelp.Typectoclearthebuffer.
mysql>showdatabases; ←检察体系已存在的数据库

+-------------+
|Database|
+-------------+
|mysql | ←确认名为test的数据库被删除,已不存在
+-------------+
1rowinset(0.00sec)
mysql>exit ←加入MySQL办事器
Bye测试MySQL
上面对MySQL举行测试。包含创建新用户,和用对干系性数据库举行数据库操纵的指令来试着创建数据库及数据表。这里,新建用户以centospub为例。
#mysql-uroot-p ←经由过程暗码用root登录
Enterpassword: ←在这里输出暗码
WelcometotheMySQLmonitor.Commandsendwith;org.
YourMySQLconnectionidis9toserverversion:4.1.20Typehelp;orhforhelp.Typectoclearthebuffer.

mysql>selectuserfrommysql.userwhereuser=centospub; ←确认centospub用户的存在与否
+---------+
|user |
+---------+
|centospub| ←确认centospub已被创建
+---------+
1rowinset(0.01sec)
mysql>exit ←加入MySQL办事器
Bye
#mysql-ucentospub-p ←用新创建的centospub用户登录MySQL办事器
Enterpassword: ←在这里输出暗码
WelcometotheMySQLmonitor.Commandsendwith;org.
YourMySQLconnectionidis10toserverversion:4.1.20

然后,删除测试用过的遗留用户。
#mysql-uroot-p ←经由过程暗码用root登录
Enterpassword: ←在这里输出暗码
WelcometotheMySQLmonitor.Commandsendwith;org.

最初,从头启动一次HTTP办事,让php-mysql反应到HTTP办事中。
#/etc/rc.d/init.d/httpdrestart ←从头启动HTTP办事
Stoppinghttpd: [OK]
Startinghttpd: [OK]终究弄掂!
(*^__^*)嘻嘻……,接上去设置phpmyadmin....
如果您觉得本篇CentOSLinux教程讲得好,请记得点击右边漂浮的分享程序,把好文章分享给你的小伙伴们!
给大家带来CentOS上MySQL数据库办事器设置***
选择交流平台,如QQ群,网站论坛等。 另外Linux上也有很多的应用软件,安装运行了这些软件后,你就可以在Linux上编辑文档、图?片,玩游戏、上网、播放多媒体文件等。 熟读写基础知识,学得会不如学得牢。 请问谁有Linux的学习心得的吗?简单的说说? 再次,Linux是用C语言编写的,我们有学习C语言的基础,读程序和编写代码方面存在的困难小一点,也是我们能较快掌握的原因之一。? 感谢老师和同学们在学习上对我的帮助。 查阅经典工具书和Howto,特别是Howto是全球数以万计的Linux、Unix的经验总结非常有参考价值通常40%的问题同样可以解决。 得到到草率的回答或者根本得不到任何Linux答案。越表现出在寻求帮助前为解决问题付出的努力,你越能得到实质性的帮助。
