nginx平滑升级make upgrade出错的解决办法

为nginx平滑升级在make upgrate那一步除了点小状况

[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

[root@web01 sbin]# pkill -int nginx
[root@web01 sbin]# ./nginxold
[root@web01 sbin]#

接着make upgrate就成功了升级

[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
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
[root@web01 nginx-1.0.5]#
[root@web01 nginx-1.0.5]#

希望对大家有帮助
