/usr/local/nginx/sbin/nginx -t detected error error
/etc/init.d/nginx start start (if httpd is turned on, turn it off first, port conflict) to
test
[root@glinux-01 conf]# vim /usr/local/nginx/html/1.php
[root@glinux-01 conf]# curl 127.0.0.1/1.php
welcome nginx[root@glinux-01 conf]#
Configure nginx default virtual host
First delete the server part in nginx.conf and add include vhost/*.conf;
mkdir /usr/local/nginx/conf/vhost
cd !$;vim aaa.conf edit aaa.conf
server
{
listen 80 default_server;
server_name aaa.com;
index index.html index.htm index.php;
root /data/wwwroot/default;
}listen 80 default_server; listen on port 80, with this mark is the default virtual host
server_name aaa.com;
index index.html index.htm index.php; specify the index page
root /data/wwwroot/default; website directory
/usr/local/nginx/sbin/nginx -t Check for syntax errors
/usr/local/nginx/sbin/nginx -s reload reload
test.
In vhost, which is the first conf, which is the default virtual host, or the conf marked with default_server
nginx user authentication
vim /usr/local/nginx/conf/vhost/test.com.conf
server
{
listen 80;
server_name test.com;
index index.html index.htm index.php;
root /data/wwwroot/test.com;
location /
{
auth_basic "Auth";
auth_basic_user_file /user/local/nginx/conf/htpasswd;
}
}location / (global authentication, if you want to specify a directory, you can write /admin, a file
~ admin.php）
{
auth_basic "Auth"; username
auth_basic_user_file /user/local/nginx/conf/htpasswd; username password file}
yum install -y httpd
htpasswd -c /usr/local/nginx/conf/htpasswd tom Create tom user and password in the directory (the first user uses -c, the second does not need to add -c, and add -c to regenerate)
/usr/local/nginx/sbin/nginx -t check syntax
/usr/local/nginx/sbin/nginx -s reload reload
Whether the test is successful: 401, indicating that a user is required
Specify username and password
domain redirection
vim /usr/local/nginx/conf/vhost/test.com.conf
server
{
listen 80;
server_name test.com test2.com test3.com;
index index.html index.htm index.php;
root /data/wwwroot/test.com;
if ($host != 'test.com' ){
rewrite ^/(.*)$ http://test.com/$1 permanent;
}
}test
