nginx 平滑升级make upgrade报错解决方法

为nginx平滑升级在make upgrate那一步除了点小状况

1 2 3 4 5 6 7 8 9

[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

1 2 3 4 5 6 7

[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

1 2 3

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

接着make upgrate就成功了升级

1 2 3 4 5 6 7 8 9 10

[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]#

注：如果在执行make upgrade命令出现错误，修改下Makefile中的upgrade标签下的路径，修改为正确的Nginx可执行文件的路径，CENTOS下一般是/usr/local/nginx/sbin/nginx
