nginx无缝升级

查看nginx版本

# nginx -V
nginx version: nginx/1.2.7
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6

下载并安装nginx nginx-1.4.7 稳定版

wget http://nginx.org/download/nginx-1.4.7.tar.gz

tar -xzf nginx-1.4.7.tar.gz
cd nginx-1.4.7
./configure --prefix=/usr/local/nginx/ --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6   #配置的就按以前的配置文件来，nginx -V 后面显示的
make

更新nginx版本

mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old
cp objs/nginx /usr/local/nginx/sbin/
make upgrade       #下面是提示信息
/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`

查看现在的nginx版本

/usr/local/nginx/sbin/nginx -v
ps aux|grep nginx |wc

第一次升级的时候make upgrade 后提示有错误，

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 make: *** [upgrade] Error 1

找到旧版本的nginx的进程号，kill掉，检查nginx的版本已经升级，
