如果改變了nginx的設定檔(nginx.conf),想重啟nginx,同樣可以透過發送系統訊號給nginx主進程的方式來進行.不過,在重新啟動之前,要確認nginx設定檔(nginx.conf)的語法是正確的,否則nginx將不會載入新的設定檔。透過下列指令可以判斷nginx設定檔是否正確:

/usr/local/webserver/nginx/sbin/nginx    -t  -c
/usr/local/webserver/nginx/conf/nginx.conf
如果設定檔不正確,螢幕將會提示設定檔的第幾行出錯:

[emerg]:unknowndirective"abc"inlusrllocauwebserverlnginxjconflnginx.conf:55
configurationfile/usr/local/webserver/ nginx/conf/nginx·conf test failed

如果設定檔正確,螢幕將提示以下兩行資訊:

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

這時候,就可以平滑重啟nginx了。

複製程式 程式碼如下:

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

或:

複製程式碼 程式碼如下:

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

以下是一些補充:

平滑重啟 kill -hup `cat /usr/local/www/nginx/logs/nginx.pid`

##平滑升級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
.這一步驟是要得到編譯參數

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

用上面這段編譯

然後make,千萬別make install

make完了在objs目錄下就多了個nginx,這個就是新版本的程式了

mv /usr/local/www/nginx/sbin/nginx /usr/local/www/nginx/sbin/nginx-20110906
cp objs/nginx /usr/local/www/nginx/sbin/nginxobjs/nginx /usr/local/www/nginx/sbin/nginxobjs
##/usr/local/www/nginx/sbin/nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local /nginx/conf/nginx.conf test is successfu

make upgrade 執行升級

執行完後/usr/local/nginx/sbin/nginx -v

#nginx: nginx version: nginx/1.0.6

nginx: built by gcc 4.1.2 20080704 (red hat 4.1.2-50)
nginx: configure arguments: --prefix=/usr/local/www/nginx --with-www/nginx --with pcre=/yujialin/pcre-8.12 --with-http_stub_status_module --with-http_gzip_static_module
