nginx 虚拟机配置
什么是虚拟主机？ 虚拟主机是一种特殊的软硬件技术，它可以将网络上的每一台计算机分成多个虚拟主机，每个虚拟主机可以独立对外提供www服务，这样就可以实现一台主机对外提供多个web服务，每个虚拟主机之间是独立的，互不影响。
nginx可以实现虚拟主机的配置，nginx支持三种类型的虚拟主机配置。 1、基于域名的虚拟主机 （server_name来区分虚拟主机——应用：外部网站） 2、基于ip的虚拟主机， （一块主机绑定多个ip地址） 3、基于端口的虚拟主机 （端口来区分虚拟主机——应用：公司内部网站，外部网站的管理后台）
1、 基于域名的虚拟主机
1、配置通过域名区分的虚拟机
[root@localhost ~]# cat /etc/nginx/nginx.confworker_processes 4;#error_log logs/error.log;worker_rlimit_nofile 102400;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; server { listen 80; server_name web.testpm.com; location / { root /var/www/nginx/; index index.html index.htm; limit_rate 2k; } } server { listen 80; server_name web.1000phone.com; location / { root /1000phone/html; index index.html index.htm; } }}2、 为 域名为 http://web.1000phone.com 的虚拟机，创建 index 文件
[root@localhost ~]# mkdir -p /1000phone/html[root@localhost ~]# vim /1000phone/html/index.html<html> <p>this is my 1000phone </p> </html>3、重新加载配置文件
# 如果编译安装的执行[root@nginx]# /usr/local/nginx/sbin/nginx -s reload# 如果 yum 安装的执行[root@nginx]# nginx -s reload4、客户端配置路由映射 在 C:WindowsSystem32driversetchosts 文件中添加两行(linux:/etc/hosts)
10.0.105.199 web.testpm.com10.0.105.199 web.1000phone.com5、 测试访问
浏览器输入：http://web.testpm.com/
浏览器输入：http://web.1000phone.com/
2、 基于ip的虚拟主机
[root@localhost ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:17:f1:af brd ff:ff:ff:ff:ff:ff inet 10.0.105.199/24 brd 10.0.105.255 scope global dynamic ens33 valid_lft 81438sec preferred_lft 81438sec inet6 fe80::9d26:f3f0:db9c:c9be/64 scope link valid_lft forever preferred_lft forever[root@localhost ~]# ifconfig ens33:1 10.0.105.201/24[root@localhost ~]# ifconfigens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.0.105.199 netmask 255.255.255.0 broadcast 10.0.105.255 inet6 fe80::9d26:f3f0:db9c:c9be prefixlen 64 scopeid 0x20<link> ether 00:0c:29:17:f1:af txqueuelen 1000 (Ethernet) RX packets 9844 bytes 1052722 (1.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 5567 bytes 886269 (865.4 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0ens33:1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.0.105.201 netmask 255.255.255.0 broadcast 10.0.105.255 ether 00:0c:29:17:f1:af txqueuelen 1000 (Ethernet)2、配置通过ip区分的虚拟机[root@localhost ~]# cat /etc/nginx/nginx.confuser root;worker_processes 4;#error_log logs/error.log;worker_rlimit_nofile 102400;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; server { listen 10.0.105.199:80; server_name web.testpm.com; location / { root /var/www/nginx/; index index.html index.htm; limit_rate 2k; } server { listen 10.0.105.201:80; server_name web.testpm.com; location / { root /1000phone/html/; index index.html index.htm; } }}3、重新加载配置文件[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload4、 测试访问浏览器输入：http://10.0.105.199浏览器输入：http://10.0.105.2015、补充-- 删除绑定的vip[root@localhost ~]# ifconfig ens33:1 10.0.105.201/24 down重启一下nginx[root@localhost ~]# systemctl restart nginx3、 基于端口的虚拟主机
[root@localhost ~]# cat /etc/nginx/nginx.confuser root;worker_processes 4;worker_rlimit_nofile 102400;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; sendfile on; keepalive_timeout 65; server { listen 80; server_name web.testpm.com; location / { root /var/www/nginx/; index index.html index.htm; limit_rate 2k; } server { listen 8080; server_name web.1000phone.com; location / { root /1000phone/html/; index index.html index.htm; } }}重新加载配置文件:[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload测试访问:浏览器输入：http://web.testpm.com/浏览器输入：http://web.1000phone.com:8080
