[root@web01 nginx-1.0.5]# 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] 错误 1
[root@web01 nginx-1.0.5]#

找不到进程文件出错，无法进行下一步
再次启动脚本，有如下提示

[root@web01 sbin]# ./nginxold
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: still could not bind()

这步是说80端口被使用
我也不清楚为什么nginx启动了却没有进程文件。
所以先把nginx kill掉，重新启动
