有時候，可能stop的時候關閉不到一些進行所占的端口，這個時候啟動也會報端口被占用。
如下圖：
[root@ZTE_OPLUS_1 nginx-1.12.0]# sh run.sh =============================================================================== HOME=/oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0 _NGINXCMD=/oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0/sbin/nginx =============================================================================== /oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0 @WORK_DIR@ /oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0 @C_CMD@ nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to [::]:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to [::]:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to [::]:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to [::]:443 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use) nginx: [emerg] bind() to [::]:443 failed (98: Address already in use) nginx: [emerg] still could not bind()
上圖報443端口被占用：使用fuser -n tcp 命令查看占用該端口的PID列表
fuser -n tcp 443
看看是什么被占用，也可以用netstat -ntpl看看誰占用，然后KILL掉占用的PID
[root@ZTE_OPLUS_1 nginx-1.12.0]# fuser -n tcp 443 443/tcp: 2330 2337 2338 2339 2340 2341
使用kill -9 PID刪除進程
[root@ZTE_OPLUS_1 nginx-1.12.0]# kill -9 2330 [root@ZTE_OPLUS_1 nginx-1.12.0]# kill -9 2337 [root@ZTE_OPLUS_1 nginx-1.12.0]# kill -9 2338 [root@ZTE_OPLUS_1 nginx-1.12.0]# kill -9 2339 [root@ZTE_OPLUS_1 nginx-1.12.0]# kill -9 2340
然后啟動即可
[root@ZTE_OPLUS_1 nginx-1.12.0]# sh run.sh =============================================================================== HOME=/oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0 _NGINXCMD=/oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0/sbin/nginx =============================================================================== /oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0 @WORK_DIR@ /oplusapp/PMSCMDB/ums-server/utils/nginx/nginx-1.12.0 @C_CMD@
