查看是否安装 rpm -qa httpd
如果已安装，则卸载：rpm -e 卸载 --nodeps 不考虑意外
下载 wget http://mirrors.sohu.com/apache/httpd-2.2.31.tar.gz
查看大小 ll -sh
解压 tar xvf
查看文件readme、install以了解该软件安装方式。
编译环境部署及若干参数解析：
./configure
--prefix=/application/apache2.2.31 //安装的目录
--enable-deflate //压缩 对文本压缩
--enable-expires //过期 浏览器缓存多久
--enable-headers //激活头
--enable-modules //激活大多数模块
--enable-so //
--with-mpm=worker //由进程生成的线程(worker)提供服务
--enable-rewrite //激活rewrite功能（伪静态）
查看错误：echo $? 或error
configure: error: in `/root/httpd-2.2.31/srclib/apr':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
configure failed for srclib/apr
解决办法：yum -y install gcc
再次检查部署环境，还有错误
checking for zlib location... not found
checking whether to enable mod_deflate... configure: error: mod_deflate has been requested but can not be built due to prerequisite failures
解决办法：yum -y install zlib-devel
make
make install
创建软链接：ln -sv apache2.2.31 apache
查看安装目录 ls （emeditor软件）
检查语法：/application/apache/bin/apachectl -t
启动：/application/apache/bin/apachectl start
或：/application/apache/bin/httpd -k start
存在以下错误，不过没关系：
httpd: apr_sockaddr_info_get() failed for min
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
查看是否启动：lsof -i :80 或 ps -ef | grep httpd
root 30976 1 0 07:51 ? 00:00:00 /application/apache2.2.31/bin/httpd -k start
daemon 30977 30976 0 07:51 ? 00:00:00 /application/apache2.2.31/bin/httpd -k start

root 31064 1464 0 07:54 pts/0 00:00:00 grep httpd
从结果来看已经启动。
在浏览器上访问主机ip，显示 It works！
如果错误，按照以下方式检查：
1、检查iptables防火墙
2、检查selinux getenforce
3、检查端口 80
4、检查进程
5、wget或curl
查看已经生效的模块：/application/apache/bin/apachectl -l
重点查看以下模块：
/application/apache/bin/apachectl -l|egrep "so|rewrite|header|expire|deflate"
mod_deflate.c
mod_expires.c
mod_headers.c
mod_rewrite.c
mod_so.c
跟踪进程使用情况 strace
strace /application/apache/bin/apachectl -M
部署站点：
cd /application/apache
cd conf/ //查看配置文件
grep -i documentroot httpd.conf //查看网站的根目录
DocumentRoot "/application/apache2.2.31/htdocs"
进入网站的根目录，放入网站文件
刷新浏览器，成功。
