nginx虚拟主机1
l nginx并发性
[iyunv@server79 conf]# vim nginx.conf
worker_processes 3 ;
[iyunv@server79 conf]# ps axu   //查看到nginx的worker进程开启了三个
nginx     4086  0.0  0.4  45556  1988 ?        S    16:48   0:00 nginx: worker p
nginx     4087  0.0  0.4  45556  1988 ?        S    16:48   0:00 nginx: worker p
nginx     4088  0.0  0.4  45556  1988 ?        S    16:48   0:00 nginx: worker p

状态检查：
location / {
           root   html;
           index  index.php index.html index.htm;
       }
       location /status{
       stub_status on;
       access_log off;
       }

检测配置是否正确：
[iyunv@server79 conf]# nginx -t
[iyunv@server79 conf]# nginx -s reload

测试：
浏览器中输入：
http：//192.168.0.179/index.html

刷新以下url的页面，requests会增加
http://192.168.0.179/status

l 虚拟主机：
[iyunv@server79 conf]# vim nginx.conf
# HTTPS server
   #
   server {
       listen       443;
       server_name  server79.example.com;

       ssl                  on;
       ssl_certificate      cert.pem;
       ssl_certificate_key  cert.pem;

       ssl_session_timeout  5m;

       ssl_protocols  SSLv2 SSLv3 TLSv1;
       ssl_ciphers  HIGH:!aNULL:!MD5;
       ssl_prefer_server_ciphers   on;

       location / {
           root   html;
           index  index.html index.htm;
       }
   }

制作加密证书：
[iyunv@server79 conf]# cd /etc/pki/tls/certs/
[iyunv@server79 certs]# make cert.pem
umask 77 ; \
PEM1=`/bin/mktemp /tmp/openssl.XXXXXX` ; \
PEM2=`/bin/mktemp /tmp/openssl.XXXXXX` ; \
/usr/bin/openssl req -utf8 -newkey rsa:2048 -keyout $PEM1 -nodes -x509 -days 365 -out $PEM2 -set_serial 0 ; \
cat $PEM1 >  cert.pem ; \
echo ""    >> cert.pem ; \
cat $PEM2 >> cert.pem ; \
rm -f $PEM1 $PEM2
Generating a 2048 bit RSA private key

writing new private key to '/tmp/openssl.DLz5xj'
-----
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) []:SHANNXI
Locality Name (eg, city) [Default City]:XI'AN
Organization Name (eg, company) [Default Company Ltd]:LINUX
Organizational Unit Name (eg, section) []:WESTOS
Common Name (eg, your name or your server's hostname) []:server79.example.com
Email Address []:root@server79.example.com

检测配置并重新加载：
[iyunv@server79 conf]# nginx -t
[iyunv@server79 conf]# nginx -s reload

测试：
浏览器https://server79.example.com

nginx虚拟主机2：
修改nginx的主配置文件：
[iyunv@server79 conf]# vim nginx.conf
server {
listen          80;
server_name     www.westos.org;
access_log      logs/westos.org.access.log main;
location / {
index index.html;
root  /usr/local/lnmp/nginx/virtualhost/westos.org;
}
}
server {
listen          80;
server_name     www.linux.org;
access_log      logs/linux.org.access.log main;  //需打开日志格式
location / {
index index.html;
root  /usr/local/lnmp/nginx/virtualhost/linux.org;
}
}

打开日志格式：

     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                     '$status $body_bytes_sent "$http_referer" '
                     '"$http_user_agent" "$http_x_forwarded_for"';

检测有无语法错误：
[iyunv@server79 conf]# nginx -t
nginx: the configuration file /usr/local/lnmp/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/lnmp/nginx/conf/nginx.conf test is successful

新建虚拟主机目录，编辑测试文件：
[iyunv@server79 nginx]# mkdir virtualhost
[iyunv@server79 nginx]# cd virtualhost/
[iyunv@server79 virtualhost]# ls
[iyunv@server79 virtualhost]# mkdir westos.org
[iyunv@server79 virtualhost]# mkdir linux.org

[iyunv@server79 westos.org]# echo www.westos.org  cuncun > index.html
[iyunv@server79 westos.org]# cat index.html
www.westos.org cuncun
[iyunv@server79 westos.org]# cd ..
[iyunv@server79 virtualhost]# cd linux.org/
[iyunv@server79 linux.org]# ls
[iyunv@server79 linux.org]# echo www.linux.org cuncun > index.html
[iyunv@server79 linux.org]# cat index.html
www.linux.org cuncun

重新加载nginx：
[iyunv@server79 conf]# nginx -s reload

测试：
在浏览器的宿主机上做解析：
vi /etc/hosts
192.168.0.179   www.westos.org   www.linux.org

浏览器中输入：
http://www.westos.org
htpp://www.linux.or
