OpenStack Swift:PID文件不'；t对应于正在运行的进程'；PIDs；can'；t重新启动服务-端口已绑定

我正在CentOS 7主机上运行带有Swift（“Swift一体机”）的Docker容器。我注意到

/var/run/swift/*.pid

文件中的pid与系统中运行的实际pid不同：

root@5293f4890016:/var/run/swift# for pidfile in `ls`; do echo $pidfile: `cat $pidfile`; done
account-auditor.pid: 219
account-reaper.pid: 285
account-replicator.pid: 291
account-server.pid: 274
container-auditor.pid: 264
container-replicator.pid: 256
container-server.pid: 267
container-sync.pid: 288
container-updater.pid: 216
object-auditor.pid: 259
object-replicator.pid: 222
object-server.pid: 297
object-updater.pid: 294
proxy-server.pid: 225

---

我在尝试（重新）配置Swift代理服务器并重新启动它时遇到问题。swift init似乎查找PID 225（请参见上面的输出），但找不到它（因为它不是实际的PID），然后尝试启动代理服务器，但端口显然已经绑定

我是否遗漏了什么，或者我的设置是否有问题

我不确定我的Swift安装有什么问题，但我重新安装了它，一切正常。如果遇到相同问题，请尝试重新安装Swift
