由于某些原因,经常会使用apache(有时用nginx)

现在我主要用它做反向代理,偶尔弄一下负载均衡和添加head头

在centos中的安装教程:

联网安装:简单,但是安装的不是最新版本,而且安装的位置是默认的(至少我现在还不会改)

参考网址: http://www.linuxidc.com/Linux/2014-11/109235.htm

源码安装: 稍微复杂点(主要是安装一些匹配的库什么的),但是自由性更高一些.

参考网址: http://www.centoscn.com/apache/2015/0713/5851.html

注意三个东西,一个是用户权限,一个是防火墙,一个是依赖的库

下面贴一个配置文件httpd.conf

## This is the main Apache HTTP server configuration file.  It contains the# configuration directives that give the server its instructions.# See 
      for detailed information.# In particular, see # 
     
      # for a discussion of each configuration directive.## Do NOT simply read the instructions in here without understanding# what they do.  They're here only as hints or reminders.  If you are unsure# consult the online docs. You have been warned.  ## Configuration and logfile names: If the filenames you specify for many# of the server's control files begin with "/" (or "drive:/" for Win32), the# server will use that explicit path.  If the filenames do *not* begin# with "/", the value of ServerRoot is prepended -- so "logs/access_log"# with ServerRoot set to "/usr/local/apache2" will be interpreted by the# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" # will be interpreted as '/logs/access_log'.## ServerRoot: The top of the directory tree under which the server's# configuration, error, and log files are kept.## Do not add a slash at the end of the directory path.  If you point# ServerRoot at a non-local disk, be sure to specify a local disk on the# Mutex directive, if file-based mutexes are used.  If you wish to share the# same ServerRoot for multiple httpd daemons, you will need to change at# least PidFile.#ServerRoot "/webAgent/apache3"## Mutex: Allows you to set the mutex mechanism and mutex file directory# for individual mutexes, or change the global defaults## Uncomment and change the directory if mutexes are file-based and the default# mutex file directory is not on a local disk or is not appropriate for some# other reason.## Mutex default:logs## Listen: Allows you to bind Apache to specific IP addresses and/or# ports, instead of the default. See also the 
      
       # directive.## Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses.##Listen 12.34.56.78:80Listen 9000ServerName www.example.com:9000## Dynamic Shared Object (DSO) Support## To be able to use the functionality of a module which was built as a DSO you# have to place corresponding `LoadModule' lines at this location so the# directives contained in it are actually available _before_ they are used.# Statically compiled modules (those listed by `httpd -l') do not need# to be loaded here.## Example:#
