本篇文章主要介绍编译无缝平滑升级Nginx 1.6.0至Nginx 1.6.1。

##下载最新软件
[root@idoseek ~]# cd /usr/local/src/ &&
 wget http://nginx.org/download/nginx-1.6.1.tar.gz &&
 tar -zxvf nginx-1.6.1.tar.gz
 
 ##解压并根据原参数编译
[root@idoseek nginx-1.6.1]# cd nginx-1.6.1 &&
./configure --prefix=/usr/local/nginx --without-http_memcached_module --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-openssl=/usr/local/src/openssl-1.0.1h --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.35 &&
make
 
##备份nginx应用程序
[root@idoseek nginx-1.6.1]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
##拷贝编译生成的nginx可执行应用程序至nginx根目录
[root@iifocus nginx-1.6.1]# cp objs/nginx /usr/local/nginx/sbin/nginx
 
##测试nginx配置是否正确
[root@idoseek nginx-1.6.1]# /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
 
##平滑升级nginx
[root@idoseek nginx-1.6.1]# make upgrade
/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`
sleep 1
test -f /usr/local/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
 
##查看nginx升级后的版本
[root@idoseek nginx-1.6.1]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.6.1
built by gcc 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC)
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --without-http_memcached_module --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-openssl=/usr/local/src/openssl-1.0.1h --with-zlib=/usr/local/src/zlib-1.2.8 --with-pcre=/usr/local/src/pcre-8.35

升级过程比较简单所以我们也就不作多的介绍了。
