服务器近一年没有更新Nginx版本了，为了提高性能和稳定，采用了最新的Nginx版本。可以到http://nginx.org/en/download.html 进行下载。升级仅花了几分钟时间就搞定了。
注：以下代码是真实环境直接配置复制进来，可以根据代码从上至下进行操作配置。
[root@kiccleaf leaf]# wget http://nginx.org/download/nginx-1.3.0.tar.gz [root@kiccleaf leaf]# tar -zxvf nginx-1.3.0.tar.gz [root@kiccleaf leaf]# cd nginx-1.3.0 #如果需要服务器个性化名称可以修改 [root@kiccleaf nginx-1.3.0]# vi src/core/nginx.h /* * Copyright (C) Igor Sysoev * Copyright (C) Nginx, Inc. */ #ifndef _NGINX_H_INCLUDED_ #define _NGINX_H_INCLUDED_ #define nginx_version 1003000 #define NGINX_VERSION "1.3.0" #可修改成自己需要的版本 #define NGINX_VER "Nginx/" NGINX_VERSION #可修改成自己需要服务的名称 #define NGINX_VAR "NGINX" #可修改成自己需要服务的名称 #define NGX_OLDPID_EXT ".oldbin" #endif /* _NGINX_H_INCLUDED_ */
#进行配置操作，根据自己的实际配置来，以下是我简单的配置
[root@kiccleaf nginx-1.3.0]# ./configure --user=www --group=www --add-module=../ngx_cache_purge-1.3 --prefix=/usr/local/nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module checking for OS + Linux 2.6.18-274.12.1.el5 x86_64 checking for C compiler ... found + using GNU C compiler + gcc version: 4.1.2 20080704 (Red Hat 4.1.2-51) …………………………编译代码省略……………… nginx path prefix: "/usr/local/nginx" nginx binary file: "/usr/local/nginx/sbin/nginx" nginx configuration prefix: "/usr/local/nginx/conf" nginx configuration file: "/usr/local/nginx/conf/nginx.conf" nginx pid file: "/usr/local/nginx/logs/nginx.pid" nginx error log file: "/usr/local/nginx/logs/error.log" nginx http access log file: "/usr/local/nginx/logs/access.log" nginx http client request body temporary files: "client_body_temp" nginx http proxy temporary files: "proxy_temp" nginx http fastcgi temporary files: "fastcgi_temp" nginx http uwsgi temporary files: "uwsgi_temp" nginx http scgi temporary files: "scgi_temp" [root@kiccleaf nginx-1.3.0]# make #看清咯，只make，而不是make install，这里升级不需要install操作 make -f objs/Makefile make[1]: Entering directory `/home/leaf/nginx-1.3.0' …………………………编译代码省略……………… make[1]: Leaving directory `/home/leaf/nginx-1.3.0' make -f objs/Makefile manpage make[1]: Entering directory `/home/leaf/nginx-1.3.0' sed -e "s|%%PREFIX%%|/usr/local/nginx|" \ -e "s|%%PID_PATH%%|/usr/local/nginx/logs/nginx.pid|" \ -e "s|%%CONF_PATH%%|/usr/local/nginx/conf/nginx.conf|" \ -e "s|%%ERROR_LOG_PATH%%|/usr/local/nginx/logs/error.log|" \ < man/nginx.8 > objs/nginx.8 make[1]: Leaving directory `/home/leaf/nginx-1.3.0'
检查配置是否正确，这里出现了警告，因为从低版本升级至高版本产生了配置的问题
[root@kiccleaf nginx-1.3.0]# ./objs/nginx -t
nginx: [warn] the "log_format" directive may be used only on "http" level in /usr/local/nginx/conf/conf.d/www.kiccleaf.com.conf:22

#升级后出现配置文件conf有错误，如果有其的虚拟主机开启了日志，也按要求移出server段放在server段的前面即可。
[root@kiccleaf nginx-1.3.0]# vi /usr/local/nginx/conf/conf.d/www.kiccleaf.com.conf

}
[root@kiccleaf nginx-1.3.0]# /usr/local/nginx/sbin/nginx -t #再检查，没有warn警告信息了
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
操作升级，出错误不管它
[root@kiccleaf nginx-1.3.0]# make upgrade #出现错误，就先不管它 /usr/local/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 successful kill -USR2 `cat /usr/local/nginx/logs/nginx.pid` cat: /usr/local/nginx/logs/nginx.pid: No such file or directory kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] make: *** [upgrade] Error 1
备份老的Nginx程序，复制新的过去
[root@kiccleaf nginx-1.3.0]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old mv: overwrite `/usr/local/nginx/sbin/nginx.old'? y [root@kiccleaf nginx-1.3.0]# cp objs/nginx /usr/local/nginx/sbin/nginx [root@kiccleaf nginx-1.3.0]# /usr/local/nginx/sbin/nginx -t #查看复制过去配置是否正确 nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful [root@kiccleaf nginx-1.3.0]# /usr/local/nginx/sbin/nginx -v #再查看一下新版本，老的是1.0.4版本 nginx version: Nginx/1.3.0 #已经是新版本
无缝升级到新版本

原来存放nginx.pid的目录下自动出现了nginx.pid.oldbin。现在新的和旧的一起在提供服务，我们执行一下命令把老的进程给Kill掉就可以了。
[root@kiccleaf nginx-1.3.0]# kill -QUIT `cat /usr/local/nginx/nginx.pid.oldbin` [root@kiccleaf nginx-1.3.0]# ps aux| grep nginx #现在查看进程只有新的了 root 30293 0.0 0.0 248720 3924 ?

好了进行访问网站，是不是正常不间断切换至最新的Nginx版本了！
