mysql> CREATE DATABASE my_db; mysql> GRANT ALL PRIVILEGES ON my_db.* TO IDENTIFIED BY 'password'; //安装apache扩展 yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql //安装php的扩展 yum install php-gd yum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc //安装mysql扩展 yum -y install mysql-connector-odbc mysql-devel libdbi-dbd-mysql [root@soft bin]# mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) ""mysql dead but subsys locked

The solution is as follows:

[root@soft mysql-4.1.19]# rm -fr /var/lib/mysql/* [root@soft mysql-4.1.19]# rm /var/lock/subsys/mysql rm: remove regular empty file `/var/lock/subsys/mysqld'? yes shell> killall mysqld shell> service mysqld start [root@soft mysql-4.1.19]# /etc/rc.d/init.d/mysqld status mysqld (pid 5457) is running... ###数据库运行正常；

1. Two important directories:

Apache has two important directories:

1. Configuration directory/ etc/httpd/conf;

2. Document directory/var/www:

2. Two configuration modes:

Two configuration methods for Apache under Fedora: Text mode (terminal command line) and graphical configuration. Both have their own advantages: graphical configuration is easier to get started, and editing the httpd.conf file directly in text mode is more free and direct.

3. Starting and shutting down the Apache service

Stopping, starting, and shutting down the Apache service can be operated in two modes: text (terminal) mode and graphical interface.

IV. Operations under the terminal

If you want to use Linux as a WWW server, I recommend not to install a graphical interface (i.e. X

window, KDE or GNOME desktop), which is very Obviously not installing these programs will significantly improve system performance, ease of operation and beautiful interface at the cost. I think the essence of Linux lies in the richness of the command line. Linux commands can accomplish all tasks.

1. Start, restart, and stop the service of Apache:

cd /etc/init.d command switches to the /etc/init.d directory and run the following command:

./httpd start //启动Apache服务 ./httpd restart //重新启动Apache服务 ./httpd stop //停止Apache服务

Automatically start the Apache service after booting up

The cd /sbin command switches to the /sbin directory and runs the chkconfig command. Parameters: ./chkconfig --level 5 httpd on

./chkconfig --list You can check whether httpd starts automatically at boot. If 5: starts, it means it starts automatically at boot.

2. Configuration

The cd /etc/httpd/conf command switches to the directory /etc/httpd/conf, use vi editor to open and edit the httpd.conf configuration, before configuring, in order To prevent configuration errors, back up httpd.conf.
