Most people do not understand the knowledge points of this article "nginx smooth restart and upgrade", so the editor summarizes the following contents, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "nginx smooth restart and upgrade how to achieve" article.

If you change the nginx configuration file (nginx.conf) and want to restart nginx, you can also do so by sending a system signal to the nginx main process. However, before restarting, make sure that the syntax of the nginx configuration file (nginx.conf) is correct, otherwise nginx will not load the new configuration file. You can determine whether the nginx configuration file is correct by using the following command:

/ usr/local/webserver/nginx/sbin/nginx-t-c

/ usr/local/webserver/nginx/conf/nginx.conf

If the configuration file is incorrect, the screen will prompt for an error on which line of the configuration file:

[emerg]: unknowndirective "abc" inlusrllocauwebserverlnginxjconflnginx.conf:55

Configurationfile/usr/local/webserver/nginx/conf/ nginx conf test failed

If the configuration file is correct, the screen prompts you with the following two lines of information:

The configuration file/usr/loca/webserver/nginx/conf/nginx.conf syntax is ok

Configuration file/usr/local/webserver/nginx/conf/nginx.conf test is successful

At this point, you can restart nginx smoothly.

The copy code is as follows:

/ usr/local/www/nginx/sbin/nginx-xs reloadx

Or:

The copy code is as follows:

Killx-hup `cat / usr/local/www/nginx/logs/ nginx.pidx`

Here are some additions:

Smoothly restart kill-hup `cat / usr/local/www/nginx/logs/ nginx.pid`

Smooth upgrade nginx

Cd / yujialin

Wget http://nginx.org/download/nginx-1.0.6.tar.gz

Tar zxvf nginx-1.0.6.tar.gz

Cd nginx-1.0.6

/ usr/local/www/nginx/sbin/nginx-v

Nginx: nginx version: nginx/1.0.4

Nginx: built by gcc 4.1.2 20080704 (red hat 4.1.2-50)

Nginx: configure arguments:-prefix=/usr/local/www/nginx-- with-pcre=/yujialin/pcre-8.12-- with-http_stub_status_module-- with-http_gzip_static_module

This step is to get the compilation parameters

. / configure-prefix=/usr/local/www/nginx-with-pcre=/yujialin/pcre-8.12-with-http_stub_status_module-with-http_gzip_static_module

Compile with the above paragraph

Then make, please don't make install.

After make, there is an extra nginx in the objs directory. This is the new version of the program.

Mv / usr/local/www/nginx/sbin/nginx / usr/local/www/nginx/sbin/nginx-20110906

Cp objs/nginx / usr/local/www/nginx/sbin/nginx

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