Virtual host IP configuration, nginx.conf file configuration and log file cutting

Today, a rough collation of the virtual host configuration, nginx.conf file configuration, and log file cutting, recorded as follows:

Nginx Virtual Host Configuration:
1, IP address configuration,
2. Bind IP address and virtual host
Details:
1, the IP address configuration:
Ifconfig eth0 192.168.0.15 netmast 255.255.255.0
Virtual IP and corresponding server block basic configuration:
Ifconfig eth0:1 192.168.0.180 broadcast 192.168.0.255 netmask 255.255.255.0
Ifconfig eth0:2 192.168.0.181 broadcast 192.168.0.255 netmask 255.255.255.0
2, the configuration of the virtual host
Server block configuration inside Nginx, corresponding to virtual IP and root directory
Simple examples such as
Server
{
Listen 192.168.0.180:80;
server_name 192.168.0.180;
Access_log/home/log/access22.log;
Location/
{
Index.html index.htm index.php;
Root/home/xuni;
}
}
Create the corresponding directories and files so that you can access the 192.168.0.180
Create the/home/log/directory,/home/xuni directory, and Touch index.htm under/home/xuni
You can access the 192.168.0.180 and see the index.htm content,
The virtual host is created

3, Nginx cache configuration and other configuration:
Examples are: Cache configuration
#所有以gif |jpg|swf end of file, cache is retained for 30 days after deletion
Location ~. *\. (gif|jpg|swf) $
{
Expires 30d; #30天释放的意思
}
Example 2
Location ~. *\. (JS|CSS)? $
{
Expires 12h;
}
4, gzip compression configuration: (Can make the original page content compressed into the original 30%, excluding less than 1K,
gzip on; #开启gzip功能
Gzip_min_length 1k; #小于1K的不适合压缩
Gzip_buffers 4 16k; #压缩后的存与内存中, apply for 4 x 16k
Gzip_http_version 1.1; #http的版本
Gzip_vary on; #判断客户端浏览器是否支持gzip技术

5. Automatic column directory configuration: AutoIndex on
Location/
{
Index.html index.htm index.php;
Root/home/xuni;
AutoIndex on; #开启自动列表, read other files when there is no index.html
}

6, the Nginx log file cutting:
Manual cutting: 1, daily Movement, MV Access.log > Time.log 2, KILL-USR1 PID
Automatic cutting: Writing scripts, crontab scheduled Tasks
The automatic cut script content is as follows:
CD Nginxlog_dir
d=$ (Date +%y%m%d)
Mv/nginxlog_dir/access.log ${d}.log
KILL-USR1 $ (cat/usr/local/nginx/nginx.pid)
