安装lamp

安装lamp的详细安装过程见 archlinux 的wiki

sudo pacman -S apache php php-apache mysql

安装结束会有下面的提示:

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 arch 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 /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/scripts/mysqlbug script!

添加新用户http

[haifeng@arch ~]$ sudo useradd -d /srv/http -r -s /bin/false -U http
[sudo] password for haifeng:
useradd: user 'http' already exists

这里 -d /srv/http 是指定用户 http 的用户目录是 /srv/http

-r 指创建一个系统账号

-s /bin/false 指定 shell

通过查看 /etc/passwd, 确实已经存在 http 用户

http:x:33:33:http:/srv/http:/bin/false

但是如果要访问 ~user/ 别忘了更改用户user的属性
chmod 711 /home/user/

默认是700

之后建议再安装 phpmyadmin

sudo pacman -S phpmyadmin
sudo pacman -S php-mcrypt

但此时安装的 phpmyadmin 位于 /usr/share/webapps/
因此必须拷贝到相应的目录, 如

sudo cp -r /usr/share/webapps/phpMyAdmin/ /srv/http/

最后测试一下, 访问 
如果显示缺少 mysqli 扩展, 则编辑 /etc/php/php.ini, 将 extension=mysqli.so 前面的分号去掉.
然后重启 apache

sudo /etc/rc.d/httpd restart
