配置apache +mongrel单实例

背景：

OS: CentOS release 3.6 (Final)

Apache: Apache/2.0.46

开始配置Apache+mongrel+rails

1. 安装ruby

wgetftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-p110.tar.gz
tarxzvfruby-1.8.6-p110.tar.gz
cdruby-1.8.6-p110
./configure--prefix=/usr/local/ruby
make&&makeinstall

在/etc/proifle中加入

exportPATH=/usr/local/ruby/bin:$PATH

2）安装gem

wgethttp://rubyforge.org/frs/download.php/17190/rubygems-0.9.2.tgz
tarxzvfrubygems-0.9.2.tgz
cdrubygems-0.9.2
rubysetup.rb

3)安装rails

geminstallrails--include-dependencies

4）安装mongrel

geminstallmongrel--include-dependencies

Select which gem to install for your platform (i686-linux)

1. mongrel 1.0.1 (mswin32)

2. mongrel 1.0.1 (ruby)

3. mongrel 1.0 (mswin32)

4. mongrel 1.0 (ruby)

5. Skip this gem

6. Cancel installation

>2

Select which gem to install for your platform (i686-linux)

1. fastthread 1.0 (ruby)

2. fastthread 1.0 (mswin32)

3. fastthread 0.6.4.1 (mswin32)

4. fastthread 0.6.4.1 (ruby)

5. Skip this gem

6. Cancel installation

>1

5)启动mongrel

cd${your_rails_app_root}
mongrel_railsstart-eproduction-p8080-rpublic-llog/m.log-Ptmp/pids/dispatch.0.pid-d

6)配置 apache

通过命令：httpd -version

发现：Apache/2.0.46

Apache已安装，于是开始略过安装过程直接配置：

vi/etc/httpd/conf/httpd.conf

文件最后加入：

<VirtualHost*:80>
ServerNamespace.mofile.com


ErrorLoglogs/space.mo.com-error_log
CustomLoglogs/space.mo.com-access_logcommon

ProxyPass/http://127.0.0.1:8080/
ProxyPassReverse/http://127.0.0.1:8080
ProxyPreserveHoston
</VirtualHost>

注意：

1）上面对于apache得配置很粗糙，把所有的请求到推倒了mongrel实例，产品环境中显然是不行的，apache作为反向代理，最好是指把动态请求推给mongrel实例。

2) 仅有单个mongrel实例使得请求变成了单进程，并发性能不太好

对于小流量的网站无所谓，一旦压力增大，恐怕就的考虑Apache+Mongrel_cluster
