設定 Linux CentOS

這篇只介紹如何設定 LAMP (Linux + Apache + MySQL + PHP) 。

記錄一下我自己的步驟。

Update all packages

# yum -y update

Install Webmin

請自行尋找最新版下載 (http://webmin.com/download.html)

# wget http://downloads.sourceforge.net/project/webadmin/webmin/1.520/webmin-1.520.tar.gz
# tar -zxvf webmin-1.520.tar.gz
# cd webmin-1.520
webmin-1.520]# ./setup.sh
  
***********************************************************************
*           Welcome to the Webmin setup script, version 1.520       *
***********************************************************************
Webmin is a web-based interface that allows Unix-like operating
systems and common Unix services to be easily administered.
  
Installing Webmin in /root/webmin-1.520 ...
  
***********************************************************************
Webmin uses separate directories for configuration files and log files.
Unless you want to run multiple versions of Webmin at the same time
you can just accept the defaults.
  
Config file directory [/etc/webmin]:
Log file directory [/var/webmin]:
  
***********************************************************************
Webmin is written entirely in Perl. Please enter the full path to the
Perl 5 interpreter on your system.
  
Full path to perl (default /usr/bin/perl):
  
Testing Perl ...
Perl seems to be installed ok
  
***********************************************************************
Operating system name:  CentOS Linux
Operating system version: 5.5
  
***********************************************************************
Webmin uses its own password protected web server to provide access
to the administration programs. The setup script needs to know :
 - What port to run the web server on. There must not be another
   web server already using this port.
 - The login name required to access the web server.
 - The password required to access the web server.
 - If the webserver should use SSL (if your system supports it).
 - Whether to start webmin at boot time.
  
Web server port (default 10000):
Login name (default admin):
Login password:
Password again:
The Perl SSLeay library is not installed. SSL not available.
Start Webmin at boot time (y/n): Y

Setup SSL for Webmin

進入 Webmin 的管理介面後，操作如下

[Webmin] -> [Webmin configuration] -> [SSL Encryption]
    set Enable SSL if available? Yes
          Redirect non-SSL requests to SSL mode? Yes

Install Apache

# yum -y install httpd mod_ssl GeoIP*

Install MySQL

[mysqld]
datadir = /var/lib/mysql
socket = /var/lib/mysql/mysql.sock
user=mysql
old_passwords=1
set-variable = table_cache=512
set-variable = key_buffer=256M
set-variable = sort_buffer=8M
set-variable = myisam_sort_buffer_size=256M
set-variable = max_allowed_packet=1M
set-variable = net_buffer_length=4M
set-variable = max_heap_table_size=256M
set-variable = join_buffer_size=8M
set-variable = read_buffer_size=16M
set-variable = read_rnd_buffer_size=8M
set-variable = sort_buffer_size=4M
set-variable = bulk_insert_buffer_size=8M
set-variable = query_cache_type=1
set-variable = query_cache_size=256M
 
big-tables
skip-locking
innodb_file_per_table = 1
 
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

Install PHP

yum -y install php php-*

Install RPMForge / memcache / gcc / ntp

以下是 For 64 位元的，如果是 32 的要自己換一下檔名，然後找最新版即可！

# rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm # yum -y install libevent memcached gcc c++ ntp
# yum -y install libevent memcached gcc c++ ntp

# vi /etc/sysconfig/clock

UTC=true
ARC=false
ZONE=Asia/Taipei

Setup Linux Firewall (in Webmin)

Setup phpMyAdmin

一樣要自己查新版的檔名喔！
# wget http://superb-sea2.dl.sourceforge.net/project/phpmyadmin/phpMyAdmin/3.3.7/phpMyAdmin-3.3.7-all-languages.tar.gz
# tar -zxvf phpMyAdmin-3.3.7-all-languages.tar.gz
# mv phpMyAdmin-3.3.7-all-languages /var/www/luke54_myadmin
view source
print?

<Location /phpMyAdmin>
    Order deny,allow
    allow from all
