编译安装httpd-2.4.9及配置其相关的工作方式
解决依赖关系httpd-2.4.9依赖于较新版本的apr和apr-util，接下来就编译安装apr和apr-util
1、编译安装apr
1
2
3
4
# tar xf apr-1.5.0.tar.bz2
# cd apr-1.5.0
# ./configure --prefix=/usr/local/apr
# make && make install
2、编译安装apr-util

# tar xf apr-util-1.5.3.tar.bz2
# cd apr-util-1.5.3
# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
# make && make install
编译安装httpd-2.4.9
httpd-2.4.9编译过程中还需依赖于pcre-devel软件包，因此也需将其安装才行
提示：挂载光盘，切换到光盘下的Package目录执行
1
# rpm -ivh pcre-devel-7.8-6.el6.x86_64.rpm

# tar xf httpd-2.4.9.tar.bz2
# cd httpd-2.4.9
# ./configure --prefix=/usr/local/httpd24 --sysconfdir=/etc/httpd24 --enable-so
--enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre
--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
--enable-modules=most --enable-mpms-shared=all --with-mpm=event
# make && make install
2、编译/etc/httpd24/httpd.conf配置文件，添加如下行即可：
PidFile "/var/run/httpd.conf"
PidFile用于指定记录httpd进程号(PID)的文件位置
3、提供SysV服务脚本/etc/rc.d/init.d/httpd24
1
# vim /etc/rc.d/init.d/httpd24

赋予脚本执行权限

# chmod +x /etc/rc.d/init.d/httpd24
将http24加入服务列表

2
# chkconfig --add httpd24
# chkconfig httpd24 on
4、启动http24服务并测试
1
# /etc/rc.d/init.d/httpd24 start
在浏览器中键入编译安装httpd-2.4.9的主机IP地址，如：10.170.2.1
此处需要说明的是，当你编译安装完httpd-2.4.9后，其DocumentRoot的默认路径为/usr/local/httpd24/htdocs，在此目录下，有一个index.html文件，更多详细内容请查看/etc/httpd24/httpd.conf配置文件
配置虚拟主机
在正式配置虚拟主机之前，需要进行说明的是：以前的httpd版本，配置虚拟主机、配置基于用户的访问控制以及配置httpd工作于https方式等只在主配置文件httpd.conf中，而编译安装的httpd-2.4.9将这些功能的配置分离出来形成了新的配置文件并利用Include包含的主配置文件中
1、编辑/etc/httpd24/httpd.conf配置文件，启动下面这项内容
1
Include /etc/httpd24/extra/httpd-vhosts.conf
2、编辑/etc/httpd24/extra/httpd-vhosts.conf文件
1
2
# cd /etc/httpd24/extra/
# vim httpd-vhosts.conf
将文件中的两个VirtualHost的所用内容注释掉，然后编辑如下内容

DocumentRoot "/web/hosta"
ServerName www.muluhe.org
Require all granted
DocumentRoot "/web/hostb"
ServerName mail.muluhe.com
Require all granted
3、编辑网页文件

# mkdir -pv /web/hosta
# mkdir -pv /web/hostb
# vim /web/hosta/index.html
内容为：Hello,www.muluhe.org
# vim /web/hostb/index.html
内容为：Hello,mail.muluhe.com
4、重启http24服务并测试
1
# /etc/rc.d/init.d/httpd24 restart
由于没有安装DNS服务器，因此利用本地文件对虚拟主机名进行解析
打开Windows主机上的C:WindowsSystem32driversetchosts文件，并添加对应IP地址与虚拟主机名，添加的内容为：
1
2
3
10.170.2.1 www.muluhe.com
10.170.2.1 mail.muluhe.com
10.170.2.1 www.muluhe.org
在浏览器中分别键入www.muluhe.com、www.muluhe.org、mai.muluhe.com，得到如下结果：
配置基于用户访问控制
1、编译配置文件/etc/httpd24/httpd.conf，启动下面的选项
1
Include /etc/httpd24/extra/httpd-userdir.conf
关闭下面的选项
1
Include /etc/httpd24/extra/httpd-vhosts.conf
2、编辑配置文件/etc/httpd24/extra/httpd-userdir.conf
1
2
# cd /etc/httpd24/extra/
# vim httpd-userdir.con
将文件中相对应的内容修改为：
1
2

9
UserDir "/usr/local/httpd24/htdocs/admin"
AllowOverride AuthConfig
Options none
AuthType Basic
AuthName "Admin Area."
AuthUserFile /etc/httpd24/.htpasswd
Require valid-user
3、提供相关文件

# cd /usr/local/httpd24/htdocs/
# mkdir admin
# vim index.html
内容为：Hello,muluhe,Welcome to admin directory
# htpasswd -c -m /etc/httpd24/.htpasswd muluhe
New password:
Re-type new password:
Adding password for user muluhe
4、重启httpd24服务并测试

# /etc/init.d/httpd24 restart
Stopping httpd:
Starting httpd: AH00526: Syntax error on line 10 of /etc/httpd24/extra/httpd-userdir.conf:
Invalid command 'UserDir', perhaps misspelled or defined by a module not included in the server configuration
呀哈，竟然出现错误，其大概的意思是说没有加载支持'UserDir'命令的模块，查看/etc/httpd24/extra/httpd-userdir.conf可以找到以下内容：
# Required module: mod_authz_core, mod_authz_host, mod_userdir
与配置文件/etc/httpd24/httpd.conf中的LoadModule中启动的模块作对比，发现没有启动LoadModule userdir_module modules/mod_userdir.so这个模块，将其启动起来再重启服务

# /etc/init.d/httpd24 restart
Stopping httpd:
Starting httpd:
在浏览器中键入www.muluhe.com/admin,可以得到如下结果
输入用户名和密码可以得到如下结果
配置httpd24工作于https
1、安装mod_ssl模块并查看
1
2
# yum -y install mod_ssl
# rpm -ql mod_ssl
2、为服务器端生成私钥，并为其提供证书
建立CA
1

5
# cd /etc/pki/CA
# (umask 077; openssl genrsa -out private/cakey.pem 2048)
# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days 3650
# touch serial index.txt
# echo 01 > serial
生成证书请求

# mkdir /etc/httpd/ssl
# cd /etc/httpd/ssl
# (umask 077; openssl genrsa -out httpd.key 1024)
# openssl req -new -key httpd.key -out httpd.csr
签署证书
1
# openssl ca -in httpd.csr -out httpd.crt -days 1000
3、编辑配置文件/etc/httpd24/httpd.conf，启动下面的选项
1
2
3
Include /etc/httpd24/extra/httpd-ssl.conf
LoadModule socache_shmcb_module modules/mod_socache_shmcb.so
LoadModule ssl_module modules/mod_ssl.so
4、编辑配置文件/etc/httpd24/extra/httpd-ssl.conf，修改下面的选项
1
2
3
4
DocumentRoot "/usr/local/httpd24/htdocs/ssl"
ServerName www.muluhe.com
SSLCertificateFile "/etc/httpd24/ssl/httpd.crt"
SSLCertificateKeyFile "/etc/httpd24/ssl/httpd.key"
5、安装证书
复制/etc/pki/CA/cacert.pem文件到Windows桌面并重命名为cacert.crt，其具体的安装步骤为：
双击桌面上"cacert.crt"-->点击安装"安装证书(I)..."-->点击"下一步"-->选择"将所有的证书放入下列存储(P)"-->点击"浏览(R)..."-->点击"下一步"-->点击"完成"-->在新的窗口中点击"yes"-->在新的窗口点击"确定"
6、编辑网页文件

# mkdir /usr/local/httpd24/htdocs/ssl
# cd /usr/local/httpd24/htdocs/ssl
# vim index.html
其内容为：Hello,SSL,I'm here!
7、重启httpd24服务并测试
1
# /etc/rc.d/init.d/httpd24 restart
在浏览器中键入www.muluhe.com，可以得到如下结果
在浏览器中键入https://www.muluhe.com，可以得到如下结果
