篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了用yum安装完mysql后没有mysqld的问题相关的知识,希望对你有一定的参考价值。
在Centos中用命令 yum install mysql安装数据库,但装完后运行mysqld启动mysql的时候提示找不到,通过 find / | grep mysqld 也没找到mysqld的目录,后来在Google上搜索下,才知道用yum安装时候mysql也有三个参数的。
yum install mysql,只是安装了mysql的client,如果你只安装了这一步,就会发现找不到mysqld。
yum install mysql-server,才安装了mysql的服务后台程序;当然还有一个MySQL-devel。
装上后就有mysqld了。
具体步骤如下:
- yum install mysql
- yum install mysql-server
- yum install mysql-devel
- chgrp -R mysql /var/lib/mysql
- chmod -R 770 /var/lib/mysql
- service mysqld start
- To start mysqld at boot time you have to copy
- support-files/mysql.server to the right place for your system
- PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
- To do so, start the server, then issue the following commands:
- /usr/bin/mysqladmin -u root password ‘new-password‘
- /usr/bin/mysqladmin -u root -h LAMP.ORG password ‘new-password‘
- Alternatively you can run:
- /usr/bin/mysql_secure_installation
- which will also give you the option of removing the test
- databases and anonymous user created by default. This is
- strongly recommended for production servers.
- See the manual for more instructions.
- You can start the MySQL daemon with:
- cd /usr ; /usr/bin/mysqld_safe &
- You can test the MySQL daemon with mysql-test-run.pl
- cd mysql-test ; perl mysql-test-run.pl
- Please report any problems with the /usr/bin/mysqlbug script!
