Apache源码安装与虚拟主机配置

 Apache
 开一台主机安装即可：
 源码安装apache
 需要源码编译安装的软件包

It works!

 生成启动脚本
 [root@localhost ~]# cp /usr/local/apache/bin/apachectl /etc/init.d/
 [root@localhost ~]# chmod +x /etc/init.d/apachectl
 [root@localhost ~]# ll /etc/init.d/apachectl
 -rwxr-xr-x. 1 root root 3434 4月 23 03:17 /etc/init.d/apachectl
 写个apache系统服务脚本, 以754的权限保存此文件
 [root@localhost ~]# vim /usr/lib/systemd/system/apache.service
 [Unit]
 Description=apache
 After=network.target
 [Service]
 Type=forking
 ExecStart=/etc/init.d/apachectl start
 ExecReload=/etc/init.d/apachectl restart
 ExecStop=/etc/init.d/apachectl stop
 PrivateTmp=true
 [Install]
 WantedBy=multi-user.target
 [root@localhost ~]# chmod 754 /usr/lib/systemd/system/apache.service
 添加开机自启动
 [root@localhost ~]# systemctl enable apache
 Created symlink from /etc/systemd/system/multi-user.target.wants/apache.service to /usr/lib/systemd/system/apache.service.
 启动服务
 [root@localhost ~]# /etc/init.d/apachectl restart
 报错：
 AH00558: httpd: Could not reliably determine the server’s fully qualified domain name, using fe80::48aa:e778:8276:5257. Set the ‘ServerName’ directive globally to suppress this message
 [root@localhost ~]# vim /usr/local/apache/conf/httpd.conf
 修改192行
 192 #ServerName www.example.com:80
 为：
 192 ServerName localhost:80
 重新启动：
 [root@localhost ~]# /etc/init.d/apachectl restart
 或者：
 [root@localhost ~]# systemctl restart apache
 查看端口
 [root@localhost ~]# netstat -antup | grep 80
 tcp6 0 0 :::80 ::???? LISTEN 100326/httpd
 客户端测试


配置apache虚拟主机
 apache虚拟主机实现有三种方法：
 1、通过不同的IP地址
 2、通过不同的域名
 3、通过不同的端口号
 三种都需要把虚拟主机功能打开：
 开启虚拟主机功能：
 [root@localhost ~]# vim /usr/local/apache/conf/httpd.conf
 #配置文件最下面 启用这一行
 475 #Include conf/extra/httpd-vhosts.conf
 去掉#号
 475 Include conf/extra/httpd-vhosts.conf
 重启服务
 [root@localhost ~]# systemctl restart apache
 通过不同的IP地址，解析不同的域名
 给服务器增加IP（另一个域名解析）
 [root@localhost ~]# ifconfig ens33:1 192.168.100.66
 [root@localhost ~]# ifconfig
 创建站点目录
 [root@localhost ~]# mkdir /www/html/{web1,web2} -p
 创建站点网页
 [root@localhost ~]# echo “www.baidu.com” > /www/html/web1/index.html
 [root@localhost ~]# echo “www.bdqn.com” > /www/html/web2/index.html
 定义虚拟主机文件：
 [root@localhost ~]# vim /usr/local/apache/conf/extra/httpd-vhosts.conf

 <VirtualHost 192.168.100.101:80>
 ServerAdmin root@baidu.com
 DocumentRoot “/www/html/web1/”
 ServerName www.baidu.com
 ServerAlias www.dummy-host.example.com
 ErrorLog “logs/dummy-host.example.com-error_log”
 CustomLog “logs/dummy-host.example.com-access_log” common


 <VirtualHost 192.168.100.66:80>
 ServerAdmin root@bdqn.com
 DocumentRoot “/www/html/web2/”
 ServerName www.bdqn.com
 ErrorLog “logs/dummy-host2.example.com-error_log”
 CustomLog “logs/dummy-host2.example.com-access_log” common


 重启服务
 [root@localhost ~]# systemctl restart apache
 测试



 通过不同的域名配置虚拟主机
 定义虚拟主机文件
 [root@localhost ~]# vim /usr/local/apache/conf/extra/httpd-vhosts.conf

 [root@localhost ~]# vim /etc/hosts
192.168.100.101 www…baidu.com
192.168.100.66 www.bdqn.com

 重启服务
 [root@localhost ~]# systemctl restart apache
 修改电脑hosts文件C:\Windows\System32\drivers\etc\hosts作解析

测试：

 通过不同的端口配置虚拟主机
 增加监听端口
 [root@localhost ~]# vim /usr/local/apache/conf/httpd.conf
 在52行添加监听端口
 51 Listen 80
 52 Listen 8080

 定义虚拟主机文件：
 [root@localhost ~]# vim /usr/local/apache/conf/extra/httpd-vhosts.conf
 <VirtualHost *:80>
 ServerAdmin root@baidu.com
 DocumentRoot “/www/html/web1/”
 ServerName www.baidu.com
 ServerAlias www.dummy-host.example.com
 ErrorLog “logs/dummy-host.example.com-error_log”
 CustomLog “logs/dummy-host.example.com-access_log” common


 <VirtualHost *:8080>
 ServerAdmin root@bdqn.com
 DocumentRoot “/www/html/web2/”
 ServerName www.bdqn.com
 ErrorLog “logs/dummy-host2.example.com-error_log”
 CustomLog “logs/dummy-host2.example.com-access_log” common


 重启服务
 [root@localhost ~]# systemctl restart apache
 验证
