Linux下安装Apache 2.4
下载Apache 2.4及依赖包
Apache官网下载：[http://httpd.apache.org/download.cgi](http://httpd.apache.org/download.cgi)
由于Apache依赖于APR、APR-Util和PCRE，所以需要下载：
APR + APR-Util：[http://apr.apache.org/download.cgi](http://apr.apache.org/download.cgi)
PCRE：[http://sourceforge.net/projects/pcre/files/pcre/](http://sourceforge.net/projects/pcre/files/pcre/)
在此，笔者使用均为目前最新版本，Apache 1.4.6，APR 1.4.1，APR-Util 2.4.1，Perl 5.14.2，PCRE 8.30
安装依赖
APR及APR-Util安装
解压缩APR及APR-Util
```
bash> sudo tar zxvf apr-1.4.6.tar.gz -C /opt/sources
bash> sudo tar zxvf apr-util-1.4.1.tar.gz -C /opt/sources
```
创建安装目录并创建软链接
```
bash> sudo mkdir /opt/software/develop/apr-1.4.6
bash> sudo mkdir /opt/software/develop/apr-util-1.4.1
bash> sudo ln -s /opt/software/develop/apr-1.4.6 /usr/local/apr
bash> sudo ln -s /opt/software/develop/apr-util-1.4.1 /usr/local/apr-util
```
安装APR及APR-Util
```
bash> cd /opt/sources/apr-1.4.6
bash> sudo ./configure --prefix=/usr/local/apr
bash> sudo make
bash> sudo make install
bash> cd /opt/sources/apr-util-1.4.1
bash> sudo ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
bash> sudo make
bash> sudo make install
```
安装PCRE
首先请确定系统安装了Perl，Perl在此不再赘述，如有需要请去官网查看安装细则：[http://www.cpan.org/src/README.html](http://www.cpan.org/src/README.html)
解压缩PCRE
```
bash> sudo tar zxvf pcre-8.30.tar.gz -C /opt/sources
```
创建PCRE安装目录及软链接
```
bash> sudo mkdir /opt/software/develop/pcre-8.30
bash> sudo ln -s /opt/software/develop/pcre-8.30 /usr/local/pcre
```
安装PCRE
```
bash> cd /opt/sources/pcre-8.30
bash> sudo ./configure --prefix=/usr/local/pcre
bash> sudo make
bash> sudo make install
```
安装Apache 2.4
解压缩Apache 2.4
```
bash> sudo tar zxvf httpd-2.4.2.tar.gz -C /opt/sources
```
创建Apache安装目录及软链接
```
bash> sudo mkdir /opt/software/develop/httpd-2.4.2
bash> sudo ln -s /opt/software/develop/httpd-2.4.2 /usr/local/apache2
```
安装Apache
```
bash> cd /opt/sources/httpd-2.4.2
```
\# 此处请根据自己要搭建的环境进行配置，我这里是为了配置PHP环境
```
bash> sudo ./configure --prefix=/usr/local/apache2 --enable-so --enable-rewrite=shared --with-mpm=prefork --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre
bash> sudo make
bash> sudo make install
```
启动Apache
通过apachectl启动Apach
```
bash> sudo /usr/local/apache2/bin/apachectl start
```
检查是否有Apache进程
```
bash> ps aux &##124; grep httpd
```
如果有Apache的进程，则证明启动成功，浏览器地址栏输入 [http://localhost](http://localhost) 试试吧～
启动成功之后，可以将apachectl拷贝到/etc/init.d下，作为service启动。
```
bash> sudo cp /usr/local/apache2/bin/apachectl /etc/init.d/httpd
bash> sudo service httpd start
```
