Detailed log files nginx **
nginx log files into log_format and access_log two parts
Log_format definition record format, the syntax is
log_format style name style details
There is a default configuration file
log_format main 'remote_addr - remote_user [time_local] "request" '
'status body_bytes_sent "$http_referer" '
'"http_user_agent" "http_x_forwarded_for"';
Use limit_rate limit the speed of data transfer client **
1, edit /etc/nginx/nginx.conf
location / {
root /var/www/nginx/;
index index.html index.htm;
limit_rate 2k; #对每个连接的限速为2k/s
}
1, edit /etc/nginx/nginx.conf
location / {
root /var/www/nginx/;
index index.html index.htm;
limit_rate 2k; #对每个连接的限速为2k/s
}
Finished modifying the configuration file, need to restart the service (reload service)
Points to note:
What is Web Hosting?
Hosting is a special hardware and software technology, it can be every computer on the network into a plurality of virtual hosts, each virtual host can independently provide external www services, this can be achieved to provide a plurality of external host web service, are independent between each virtual host, independently of each other.
nginx can achieve virtual host configuration, nginx supports three types of virtual host configuration.
1, based virtual hosting (server_name to distinguish between virtual hosts - Application: External website)
2, ip-based virtual host, and (a host bind multiple ip address)
3, based on the virtual host port (port to distinguish virtual host - application: the company's internal Web site, external website management background)
the primary configuration server module on it, you can put the main server configuration file comments, and then again in the new configuration under /etc/nginx/conf.d/ end with .conf file must be written on what content to
the main configuration file must include /etc/nginx/conf.d/*.conf (at http module below)
1, name-based virtual hosting
1, configured through domain name to distinguish the virtual machine
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;
}
}
[root@localhost nginx]# vim /var/www/nginx/index.html
hello tianyun
2, for the domain name web.1000phone.com virtual machine, create index file
[root@localhost ~]# mkdir -p /1000phone/html
[root@localhost ~]# vim /1000phone/html/index.html
this is my 1000phone
3, reload the configuration file
# 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 reload
4, the client configuration parsing
in C: \ Windows \ System32 \ drivers \ etc \ hosts file to add two lines (linux: / etc / hosts)
10.0.105.199 web.testpm.com
10.0.105.199 web.1000phone.com
5, test access
Enter the browser: http: //web.testpm.com/
Enter the browser: HTTP: //web.1000phone.com/
2, ip-based virtual hosts
[root@localhost ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1

2, the configuration of the virtual machine by distinguishing ip
server {
listen 80;
server_name 10.0.105.199;
location / {
root /var/www/nginx/;
index index.html index.htm;
limit_rate 2k;
}
server {
listen 80;
server_name 10.0.105.201;
location / {
root /1000phone/html/;
index index.html index.htm;
}
}
3, reload the configuration file
[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload
4, test access
browser enter: http: //10.0.105.199
browser enter: HTTP: //10.0.105.201
5, supplement
- remove the binding of temporary ip
[root@localhost ~]# ifconfig ens33:1 10.0.105.201/24 down
Restart the nginx
[root@localhost ~]# systemctl restart nginx
3, Port-based virtual hosts
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.testpm.com;
location / {
root /1000phone/html/;
index index.html index.htm;
}
}
Reload the configuration file:
[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload
Test Access:
browser, enter: http: //web.testpm.com/
browser and enter: http: //web.1000phone.com: 8080
