1.建用户
[root]# groupadd apache
[root]# useradd apache -g apache
[root]# passwd apache
[root]# su - apache
2.下载openssl-1.0.2g.tar.gz到用户目录~(/home/apache/)
[apache]#tar -zxvf openssl-1.0.2g.tar.gz
[apache]#cd openssl-1.0.2g
[apache]#mkdir /opt/openssl
[apache]#./config --prefix=/opt/openssl
[apache]#make && make install
3.下载httpd-2.2.22.tar.gz到用户目录~(/home/apache/)
[apache]#tar -zxvf httpd-2.2.22.tar.gz
[apache]#cd ../httpd-2.2.22
[apache]#export LDFLAGS=-ldl //执行下面命令前最好加上这句话，否则可能报错： configure: error: ... Error, SSL/TLS libraries were missing or unusable
[apache]#./configure --prefix=/opt/httpd --enable-so--enable-info--enable-headers --enable-mods-shared=all --enable-ssl=static --with-ssl=/opt/openssl
指定模块：./configure --prefix=/opt/httpd --enable-so--enable-info--enable-headers --enable-mods-shared="proxy proxy_http proxy_connect" --enable-ssl=static --with-ssl=/opt/openssl --enable-rewrite --enable-speling --enable-forward
[apache]#make //编译apache
[apache]#make install //安装apache
或者编译并且安装apache
[apache]#make && make install
注意，非root用户1024以下端口不可用，需要修改默认80端口为其他可用端口
vi /opt/httpd/conf/httpd.conf
4.查看代理模块及安装：
./apachectl -M|grep proxy
如果没有任何模块，安装步骤：(注意：proxy_util.c是基础模块，必须先安装。如果出错，每个命令后都加上)
cd /home/apache/httpd-2.2.22/modules/proxy
/opt/httpd/bin/apxs -c -i -a mod_proxy.c proxy_util.c
/opt/httpd/bin/apxs -c -i -a mod_proxy_http.c
/opt/httpd/bin/apxs -c -i -a mod_proxy_ftp.c
/opt/httpd/bin/apxs -c -i -a mod_proxy_connect.c
/opt/httpd/bin/apxs -c -i -a mod_proxy_balancer.c
/opt/httpd/bin/apxs -c -i -a mod_proxy_scgi.c
/opt/httpd/bin/apxs -c -i -a mod_proxy_ajp.c ajp*.c
httpd.conf代理配置，举例：
#开启代理服务，客户端可指定当前IP及端口作为代理配置
ProxyRequests On
#代理指向如果是https协议，必须加上该属性，否则转发错误
SSLProxyEngine On
ProxyPass/https/https://url/
ProxyPassReverse/https/https://url/
ProxyPass/http/http://url/
ProxyPassReverse/http/http://url/
Listen 8081
<IfModule mod_proxy.c>
<VirtualHost *:8081>
ProxyRequests On
#配置允许访问的目的地址以及可使用代理的来源地址
<Proxy *>
Order deny,allow
Allow from all
#Allow from IP1 IP2...
</Proxy>
</VirtualHost>
</IfModule>
SSL加虚拟机配置
Listen 9443
NameVirtualHost *:9443
<VirtualHost *:9443>
#ServerName domain:9443
DocumentRoot htdocs
DirectoryIndex index.htm
#SSLEngine on
#SSLVerifyClient require
SSLVerifyDepth 10
#SSLCertificateFile conf/server.crt
#SSLCertificateKeyFile conf/server.key
#SSLCACertificateFile conf/CFCA_TEST_CS_CA.cer
#SSLCertificateChainFile conf/CFCA_TEST_OCA1.cer
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
SSLOptions +StdEnvVars
#ProxyRequests On
#SSLProxyEngine On
#ProxyPass/http/http://url/
#ProxyPassReverse/http/http://url/
</VirtualHost>
如果具有root用户权限，可把apache加入到自动启动服务：
[root]#chkconfig --list httpd //查看httpd服务是否已存在
[root]#chkconfig httpd off //关闭系统自带了httpd的服务，如果存在httpd服务
[root]#service httpd status //查看自带httpd服务状态
[root]#/opt/httpd/bin/apachectl -k start //linux启动apache命令
[root]#netstat -an|grep :80 //查看linux80端口是否开启
[root]#ps -aux|grep httpd //linux下查看apache进程
[root]#cd ../..
[root]#cp /opt/httpd/bin/apachectl /etc/rc.d/init.d/apache //拷贝apache启动脚本
[root]#vi /etc/rc.d/init.d/apache // 这里是编辑apache启动脚本
在开头的#！/bin/sh下面加上（未知作用）
#chkconfig: 2345 85 15
[root]#chkconfig --add apache //添加apache服务
[root]#chkconfig --list apache //列出apache服务
[root]#service apache stop //停止apache服务
[root]#netstat -an|grep :80 //查看linux的80端口是否关闭
[root]#ps -aux|grep httpd //查看是否存在httpd服务，若果之前自带httpd服务启动的话会导致新添加的apache服务启动失败
[root]#service apache start //启动apache服务
打开服务器ip地址，看是否出现了It works!，如果出现的话，apache已经安装成功了
root用户下，Apache的启动、关闭、重启
启动命令：service httpd start
关闭命令：service httpd stop
重启命令：service httpd restart
状态查询：service httpd status
非root用户下，Apache的启动、关闭、重启
启动命令：/opt/httpd/bin/apachectl start
关闭命令：/opt/httpd/bin/apachectl stop
重启命令：/opt/httpd/bin/apachectl restart
状态查询：/opt/httpd/bin/apachectl status
