一、虚拟主机配置
1、基于域名的虚拟主机
基于域名的虚拟主机就是通过不同的域名来区分提供web服务的主机
1.配置nginx配置文件
[root@Nginx conf]# vim server.conf
将nginx.conf配置文件中的server段取出创建了server.conf，在nginx.conf中include server.conf
[root@Nginx html]# grep -E -v "#|^$" ../conf/server.conf
server {
listen 80;
server_name xn2.51cto.com;
location / {
root html/xn2;
index index.html;
}
}
server {
listen 80;
server_name xn3.51cto.com;
location / {
root html/xn3;
index index.html;
}
}
server {
listen 80;
server_name xn1.51cto.com;
location / {
root html/xn1;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
2.创建虚拟主机目录及文件
[root@Nginx conf]# cd ../html/
[root@Nginx html]# mkdir -pv xn{1,2,3}
mkdir: 已创建目录 "xn1"
mkdir: 已创建目录 "xn2"
mkdir: 已创建目录 "xn3"
[root@Nginx html]# echo "This is xn1" >> xn1/index.html
[root@Nginx html]# echo "This is xn2" >> xn2/index.html
[root@Nginx html]# echo "This is xn3" >> xn3/index.html
[root@Nginx html]# cat xn1/index.html
This is xn1
3.平滑重启nginx
[root@Nginx html]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@Nginx html]# nginx -s reload
4.修改hosts文件，并测试nginx虚拟主机
[root@Nginx html]# echo "192.168.0.110 xn1.51cto.com" >> /etc/hosts
[root@Nginx html]# echo "192.168.0.110 xn2.51cto.com" >> /etc/hosts
[root@Nginx html]# echo "192.168.0.110 xn3.51cto.com" >> /etc/hosts
[root@Nginx html]# curl xn1.51cto.com
This is xn1
[root@Nginx html]# curl xn2.51cto.com
This is xn2
[root@Nginx html]# curl xn3.51cto.com
This is xn3
2、基于端口的虚拟主机
1.配置[root@Nginx conf]# vim server.conf[root@Nginx conf]# grep -E -v "#|^$" server.conf server {listen 8002;server_name xn2.51cto.com;location / { root html/xn2; index index.html;} } server { listen 8003; server_name xn3.51cto.com; location / { root html/xn3; index index.html; } } server { listen 80; server_name xn1.51cto.com; location / { root html/xn1; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }2.测试[root@Nginx conf]# nginx -tnginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful[root@Nginx conf]# nginx -s reload[root@Nginx conf]# curl 192.168.0.110:80This is xn1[root@Nginx conf]# curl 192.168.0.110:8002This is xn2[root@Nginx conf]# curl 192.168.0.110:8003This is xn3
3、基于IP的虚拟主机
1.为网卡配置多个IP[root@Nginx conf]# ip addr add 192.168.0.10/24 dev eth0[root@Nginx conf]# ip addr add 192.168.0.20/24 dev eth0[root@Nginx conf]# ip add | grep eth02: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 inet 192.168.0.110/24 brd 192.168.0.255 scope global eth0 inet 192.168.0.10/24 scope global secondary eth0 inet 192.168.0.20/24 scope global secondary eth0之后 ping测试IP连通性2.配置Nginx[root@Nginx conf]# grep -E -v "#|^$" server.conf server {listen 192.168.0.10:8002;server_name xn2.51cto.com;location / { root html/xn2; index index.html;} } server { listen 192.168.0.20:8003; server_name xn3.51cto.com; location / { root html/xn3; index index.html; } } server { listen 80; server_name xn1.51cto.com; location / { root html/xn1; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }3.测试[root@Nginx conf]# curl 192.168.0.10:8002This is xn2[root@Nginx conf]# curl 192.168.0.20:8003This is xn3[root@Nginx conf]# curl 192.168.0.110This is xn1
基于域名，IP,端口可混用，具体使用是基于域名使用的较多。基于域名的虚拟主机可配置多个域名，中间以空格分开。

二、Nginx状态信息模块
1、ngx_http_stub_status_module模块提供Nginx的基本访问状态信息，在编译时要加入--with-http_stub_status_module参数
1.编辑配置文件[root@Nginx conf]# grep -E -v "#|^$" server.conf server { listen 80; location / { root html/xn1; index index.html index.htm; }location = /status { stub_status on; access_log off; allow 192.168.0.0/24; deny all;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }其中状态信息页访问不记录日志，并设置了可访问的IP段。2.测试访问[root@Nginx conf]# curl http://192.168.0.110/statusActive connections: 1 server accepts handled requests 30 30 35 Reading: 0 Writing: 1 Waiting: 0
status显示结果详解：
Active connections: 1 ：活动连接数
server accepts handled requests：处理的连接，创建的握手，总共处理多少次请求
Reading: 读取客户端的信息数
Writing: 返回给客户端的信息数
Waiting: 开启keep-alive时，waiting = active - （reading + writing）
更多详细信息请看：http://nginx.org/en/docs/http/ngx_http_stub_status_module.html
三、Nginx访问认证
Nginx访问认证为网站设置帐号密码，每次请求都要先认证帐号密码才可以访问网站。
1、配置文件[root@Nginx conf]# grep -E -v "#|^$" server.conf server { listen 80; location / { root html/xn1; index index.html index.htm; }location = /status { stub_status on; access_log off; allow 192.168.0.0/24; deny all; auth_basic"please imput user and password:"; auth_basic_user_file /usr/local/nginx/conf/htpasswd;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }Note： auth_basic：后跟提示信息 auth_basic_user_file：帐号密码认证文件的路径 auth_basic_user_file文件的格式为name:password ,password为加密的 2、准备认证文件使用apache自带的htpasswd命令直接生成[root@Nginx conf]# htpasswd -bc /usr/local/nginx/conf/htpasswd jym 123456Adding password for user jym[root@Nginx conf]# cat htpasswd jym:Rq5uy9jvgi.gc[root@Nginx conf]# chmod 400 htpasswd [root@Nginx conf]# chown nginx htpasswd
