需求说明
分别用httpd-2.2和httpd-2.4 实现以下功能：
两个虚拟主机，名字为
www.a.com、www.b.org。www.a.com页面文件为/opt/a.com/htdocs，访问日志文件路径/var/log/httpd/a.com/access.log，错误日志文件路径/var/log/httpd/a.com/error.log。两种日志做好按天切割日志。www.b.org页面文件为/opt/b.org/htdocs，访问日志文件路径/var/log/httpd/b.org/access.log，错误日志文件路径/var/log/httpd/b.org/error.log。两种日志做好按天切割日志。通过
www.a.com/server-status输出其状态信息，且要求只允许提供账号的用户访问；wwww.a.com/server-status只允许192.168.5.0/24 网络中的主机访问。同时为这两个虚拟主机提供https服务。
说明：测试中的httpd全部为yum安装，httpd-2.2会在CentOS 6中演示，httpd-2.4会在CentOS 7中演示。
httpd-2.2 配置
安装
安装可以使用yum安装也可以使用编译安装，但是CentOS 6中系统yum源默认的是httpd-2.2版本，这个需要注意。
#yum install -y httpd httpd-devel mod_ssl
ssl证书签署
以下操作是在CA机器上进行的操作。
生成CA证书
# yum install -y openssl openssl-devel
# cd /etc/pki/CA/
# (umask 077; openssl genrsa 2048 > private/cakey.pem)
# openssl req -new -x509 -key private/cakey.pem -days 3655 -out cacert.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ‘.‘, the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:ShangHai
Locality Name (eg, city) [Default City]:ShangHai
Organization Name (eg, company) [Default Company Ltd]:example
Organizational Unit Name (eg, section) []:ops
Common Name (eg, your name or your server‘s hostname) []:www.example.com
Email Address []:[email protected]
# touch index.txt serial
# echo 01 > serial
a.com域名证书签署
# mkdir /opt/ssl/a.com -p
# (umask 077 ;openssl genrsa 2048 > a.key)
# openssl req -new -key a.key -out a.csr

测试
创建网站测试的文件
[[email protected] ~]# cat /opt/a.com/htdocs/index.html
<h1>www.a.com</h1>
[[email protected] ~]# cat /opt/b.org/htdocs/index.html
<h1>www.b.org</h1>
导入根证书
请将CA 证书中的cacert.pem 文件导入到浏览器中的受信任的根证书中。
相关所需文件的创建
# mkdir /var/log/httpd/a.com/
# mkdir /var/log/httpd/b.org/
# /etc/init.d/httpd start
# htpasswd -cm /etc/httpd/conf/.htpasswd bols
测试
测试前请在hosts文件写入域名和想对应的解析IP：
# curl http://www.a.com/index.html
<h1>www.a.com</h1>
# curl http://www.b.org/index.html
<h1>www.b.org</h1>
# openssl s_client -connect www.b.org:443 -CAfile /etc/pki/CA/cacert.pem
......

安装配置出现问题：
语法检测时出现警告
# httpd -t
httpd: apr_sockaddr_info_get() failed for db-02
httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.0.1 for ServerName
[Mon Nov 28 16:44:58 2016] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
[Mon Nov 28 16:44:58 2016] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Mon Nov 28 16:44:58 2016] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
Syntax OK
首先第一个是httpd的配置文件中ServerName 没有指定：
# vim /etc/httpd/conf/httpd.conf +276
ServerName *:80
之后在检测开始报错：
# httpd -t
[Mon Nov 28 16:45:42 2016] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
[Mon Nov 28 16:45:42 2016] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Mon Nov 28 16:45:42 2016] [warn] _default_ VirtualHost overlap on port 443, the first has precedence
Syntax OK
这个是由于NameVirtualHost 没有指定：
vim /etc/httpd/conf/httpd.conf +991
NameVirtualHost *:80
NameVirtualHost *:443
配置日志滚动时出现滚动日志失败
原因：问题原因不清楚，但是解决方法是将日志文件使用绝对路径，不要使用相对路径。
httpd-2.4
安装
# yum install -y httpd httpd-devel mod_ssl
CA证书配置
ssl证书还是用于在CentOS 6系统中创建的，并把文件拷贝至/etc/httpd/ssl目录中，注意这个目录需要手动创建。
网站测试文件创建
# cat /opt/a.com/htdocs/index.html
<h1>www.a.com</h1>
# cat /opt/b.org/htdocs/index.html
<h1>www.b.org</h1>
认证文件创建
htpasswd 命令的使用请自行谷歌。
# htpasswd -cm /etc/httpd/conf/htpasswd bols
配置
<VirtualHost *:80>
ServerName www.a.com
DocumentRoot "/opt/a.com/htdocs"

测试
测试和CentOS 6中一样，测试的结果就不在贴出。
说明
在CentOS 7 中的配置和使用和CentOS 6有以下几个区别（个人总结）：
启动httpd不在是用service命令而是使用systemctl命令。
任意目录下的页面只有显式授权才能被访问。
访问控制配置如下：
允许所有主机访问：Require all granted
拒绝所有主机访问：Require all deny
授权指定来源的IP访问：Require ip IPADDR
拒绝指定来源的IP访问：Require not ip IPADDR
授权指定来源的主机访问：Require host HOSTNAME
拒绝指定来源的主机访问：Require not host HOSTNAME
关于日志滚动的说明：
httpd 日志滚动可以用rotatelogs、cronolog或者脚本滚动。
日志滚动可以用rotatelogs 是httpd自带的日志滚动工具，自己测试在httpd-2.4中没有成功。
cronolog 是在epel源中的一个日志滚动工具，需要安装。
脚本控制滚动这个看自己业务需求进行写了。
