標籤:cti mysql安裝 mod sdn net lamp report data- chgrp
在Centos中用命令 yum install mysql安裝資料庫,但裝完後運行mysqld啟動mysql的時候提示找不到,通過 find / | grep mysqld 也沒找到mysqld的目錄,後來在Google上搜尋下,才知道用yum安裝時候mysql也有三個參數的。
yum install mysql,只是安裝了mysql的client,如果你只安裝了這一步,就會發現找不到mysqld。
yum install mysql-server,才安裝了mysql的服務背景程式;當然還有一個MySQL-devel。
裝上後就有mysqld了。
具體步驟如下:
[plain] view plain copy
- 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!
