操作系统CentOS 7
linux下，默认Apache安装软件，其路径是随着开发软件人员的习惯而定，在开发过程中会经常不知道到所需的程序路径，因此手动安装程序对后续的使用会提供非常大的便利
一：准备
1.安装 apr
下载地址：http://apr.apache.org/download.cgi
[root@lcoalhost:/usr/local/src]# tar zxvf apr-1.5.2.tar.gz
[root@lcoalhost:/usr/local/src/apr-1.5.2]# ./configure --prefix=/usr/lcoal/apr
[root@lcoalhost:/usr/local/src/apr-1.5.2]# make
[root@lcoalhost:/usr/local/src/apr-1.5.2]# make install
2.安装 apr-util
下载地址：http://apr.apache.org/download.cgi
[root@lcoalhost:/usr/local/src]# tar zxvf apr-util-1.5.4.tar.gz
[root@lcoalhost:/usr/local/src/apr-util-1.5.4]# ./configure --prefix=/usr/lcoal/apr-util --with-apr=/usr/lcoal/apr
[root@lcoalhost:/usr/local/src/apr-util-1.5.4]# make
[root@lcoalhost:/usr/local/src/apr-util-1.5.4]# make install
3.安装 pcre
下载地址：http://pcre.org/
[root@lcoalhost:/usr/local/src]# tar jxvf pcre-8.37.tar.gz
[root@lcoalhost:/usr/local/src/pcre-8.37]# ./configure --prefix=/usr/lcoal/pcre
[root@lcoalhost:/usr/local/src/pcre-8.37]# make
[root@lcoalhost:/usr/local/src/pcre-8.37]# make install
注意：如果在安装 pcre 时，遇到问题：configure: error: You need a C++ compiler for C++ support.
解决方法：yum install -y gcc gcc-c++
二：安装Apache
下载地址：http://httpd.apache.org/
[root@lcoalhost:/usr/local/src]# tar zxvf httpd-2.4.16.tar.gz
[root@lcoalhost:/usr/local/src/httpd-2.4.16]# ./configure --prefix=/usr/lcoal/apache --with-apr=/usr/lcoal/apr --with-apr-util=/usr/lcoal/apr-util --with-pcre=/usr/lcoal/pcre
[root@lcoalhost:/usr/local/src/httpd-2.4.16]# make
[root@lcoalhost:/usr/local/src/httpd-2.4.16]# make install
三：配置
1.启动
[root@localhost:/usr/local/apache]# ./bin/apachectl start
2.开机启动
打开文件：/etc/rc.local
[root@localhost:/]# vim /etc/rc.local
添加：/work/installed/apache/bin/apachectl start
3.将里面的#ServerName localhost:80注释去掉即可，避免出现httpd: Could not reliably determine the server's fully qualified domain name错误提示
OK啦 http://localhost OR http://ip
