1. Default Virtual Host

Modify configuration files

vim /usr/local/nginx/conf/nginx.conf

Add "include vhost/*.conf;" in the last penultimate line (all files ending with. conf under vhost will be loaded so that all virtual host configuration files can be placed in the vhost directory)

 

Create vhost, edit configuration file

mkdir /usr/local/nginx/conf/vhost
cd /usr/local/nginx/conf/vhost/
vim default.conf

#Add the following code
server
{
    listen 80 default_server;
    server_name cheese.com;
    index index.html index.htm index.php;
    root /data/nginx/default;
}

Check for errors

/usr/local/nginx/sbin/nginx -t

restart

/usr/local/nginx/sbin/nginx -s reload

Create index pages

echo " test.com " > /data/nginx/test.com/index.html

Visit

curl -I -x127.0.0.1:80 test.com

 

 

2. User authentication

Create a new virtual host

cd /usr/local/nginx/conf/vhost/
vim default.conf

#Add the following
server
{   listen 80;
           server_name test.com;
           index index.html index.htm index.php;
           root /data/nginx/test.com;

           location  /
           {
               auth_basic              "Auth";
               auth_basic_user_file   /usr/local/nginx/conf/htpasswd;
           }
}

Auth_basic opens authentication, auth_basic_user_file specifies user password file

With htpasswd of httpd:

yum install -y httpd
htpasswd -c /usr/local/nginx/conf/htpasswd admin

Check for errors and restart

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

Verification with curl command

mkdir /data/nginx/test.com
echo " test.com " > /data/nginx/test.com/index.html
curl -I -x127.0.0.1:80 test.com

401 indicates that authentication is required, and browsers can be used to authenticate.

 

Authenticate the directory by adding a path after location

vim /usr/local/nginx/conf/vhost/test.com.conf

server
{   listen 80;
           server_name test.com;
           index index.html index.htm index.php;
           root /data/nginx/test.com;

           location  /admin/
           {
               auth_basic              "Auth";
               auth_basic_user_file   /usr/local/nginx/conf/htpasswd;
           }
}

echo "directory auth" > /data/nginx/test.com/admin/index.html

 

3. Domain name redirection

Editing configuration files

vim /usr/local/nginx/conf/vhost/test.com.conf

server
{   listen 80;
           server_name test.com test1.com;
           index index.html index.htm index.php;
           root /data/nginx/test.com;


           if ($host != 'test.com' ) {
               rewrite  ^/(.*)$  http://test.com/$1  permanent;
           }
}

Ser_name can be followed by multiple domain names, and permanent is a permanent redirection, equivalent to R=301 of httpd

 

Detection, restart, testing

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
curl -x127.0.0.1:80  test1.com/123.txt -I

Result

 

4. Nginx access log

Editing configuration files

vim /usr/local/nginx/conf/vhost/test.com.conf

Add access_log/tmp/test.log combined_realip;.

server
{   listen 80;
           server_name test.com test1.com;
           index index.html index.htm index.php;
           root /data/nginx/test.com;


           if ($host != 'test.com' ) {
               rewrite  ^/(.*)$  http://test.com/$1  permanent;
           }

           access_log /tmp/test.log combined_realip;
}

access_log to specify the location of the log, followed by the format name of the specified log

 

Verification, restart, verification

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
curl -x127.0.0.1:80 test.com/test

See

cat /tmp/test.log

 

Cutting Nginx logs requires the help of system cutting tools or custom scripts

vim /usr/local/sbin/nginx_log_rotate.sh

#Add the following
#!/bin/bash
d=`date -d "-1 day" +%Y%m%d`
logdir="/tmp"                                            #logdir is the path where nginx logs are stored as / tmp
nginx_pid="/usr/local/nginx/logs/nginx.pid"
cd $logdir
for log in `ls *.log`
do
    mv $log $log-$d
done
/bin/kill -HUP `cat $nginx_pid`

Increased mission plan

/bin/bash /usr/local/sbin/nginx_log_rotate.sh

 

5. Configure static files not to log and add expiration time

Editing configuration files

vim /usr/local/nginx/conf/vhost/test.com.conf

server
{   listen 80;
           server_name test.com test1.com;
           index index.html index.htm index.php;
           root /data/nginx/test.com;

           location  /admin/
           {
               auth_basic              "Auth";
               auth_basic_user_file   /usr/local/nginx/conf/htpasswd;
           }


           if ($host != 'test.com' ) {
               rewrite  ^/(.*)$  http://test.com/$1  permanent;
           }

           location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
           {
                 expires      7d;
                 access_log off;
           }

            location ~ .*\.(js|css)$
           {
                 expires      12h;
                 access_log off;
           }
           access_log /tmp/test.log combined_realip;
}

location~can specify the corresponding static file, expires configuration expiration time, access_log off can not record access log

 

Testing (creating js, jpg, jss files)

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload
echo "ok is ok" > /data/nginx/test.com/01.js
echo "good is good" > /data/nginx/test.com/02.jpg
touch /data/nginx/test.com/01.jss

Verification

curl -I -x127.0.0.1:80 test.com/01.js
curl -I -x127.0.0.1:80 test.com/02.jpg
curl -I -x127.0.0.1:80 test.com/01.jss

  

You can see the corresponding time size of Cache-control, or you can see the access log.

cat /tmp/test.log

  

As you can see, there is only jss, no js and jpg
