本案例在虚拟机中的CentOS7中进行
案例中在nginx.conf文件中相关说明如下:
配置了两个主机www.server1.com和www.server2.com,前者基于主机名,后者基于IP
每个虚拟主机里使用不同的location块进行请求处理
主机myServer2还进行了错误页面的重定向
模拟生产场景,准备三台虚拟主机,主机IP地址如下:
- 主机0: 192.168.245.127 模拟进行页面访问
- 主机1: 192.168.245.129 www.server1.com
- 主机2: 192.168.245.131 www.server2.com
# 在安装之前需要安装依赖包
yum install -y gcc gcc-c++ automake pcre pcre-devel zlib zlib-devel open openssl-devel
# 然后从官网下载相关安装包解压编译即可主机0的host配置
添加www.server1.com,由于主机3是配置基于IP访问,所以不需要添加进去
vi /etc/hosts
192.168.245.129 www.server1.com主机1的host配置
vi /etc/hosts
192.168.245.129 www.server1.com注:如果是Windows主机,编辑C:\Windows\System32\drivers\etc下对应的hosts文件即可
在访问时curl 192.168.245.131:8001/server/location1/出现错误
错误: curl: (7) Failed connect to 192.168.245.131:8001; No route to host
问题分析: 没有到server2的路由,排查发现防火墙策略没开
解决方案: 开放nginx端口
systemctl start firewalld
firewall-cmd --zone=public --add-port=8001/tcp --permanent
firewall-cmd --reload-
