Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
5.1.1 snapshot
commit id 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Proxy A stop；Proxy B alive.
### Actual behavior
Proxy A stop；Proxy B dead.
### Reason analyze (If you can)
Can't
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
1. Build Proxy
2. Rename Proxy to 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae
3. add MySQL connector to lib
4. Config server.yaml
```
mode:
type: Cluster
repository:
type: ZooKeeper
props:
namespace: zklock
server-lists: localhost:2181
retryIntervalMilliseconds: 500
timeToLiveSeconds: 60
maxRetries: 3
operationTimeoutMilliseconds: 500
overwrite: true
rules:
- !AUTHORITY
users:
- root@%:root
- sharding@:sharding
provider:
type: ALL_PRIVILEGES_PERMITTED
props:
max-connections-size-per-query: 1
kernel-executor-size: 16 # Infinite by default.
proxy-frontend-flush-threshold: 128 # The default value is 128.
proxy-hint-enabled: false
sql-show: false
check-table-metadata-enabled: false
show-process-list-enabled: false
# Proxy backend query fetch size. A larger value may increase the memory usage of ShardingSphere Proxy.
# The default value is -1, which means set the minimum value for different JDBC drivers.
proxy-backend-query-fetch-size: -1
check-duplicate-table-enabled: false
proxy-frontend-executor-size: 0 # Proxy frontend executor size. The default value is 0, which means let Netty decide.
# Available options of proxy backend executor suitable: OLAP(default), OLTP. The OLTP option may reduce time cost of writing packets to client, but it may increase the latency of SQL execution
# and block other clients if client connections are more than `proxy-frontend-executor-size`, especially executing slow SQL.
proxy-backend-executor-suitable: OLAP
proxy-frontend-max-connections: 0 # Less than or equal to 0 means no limitation.
sql-federation-enabled: false
# Available proxy backend driver type: JDBC (default), ExperimentalVertx
proxy-backend-driver-type: JDBC
```
5. Build another Proxy
```
cp -r 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae.bak
```
6. start Proxy A;stop Proxy B
```
cd 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae;./bin/start.sh 3333
cd 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae.bak;./bin/start.sh 4444
```
8. stop Proxy A
```
cd 5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae;./bin/stop.sh 3333
```
10. Then we can find Proxy B is dead.

Hi @wsm12138
This issue may be related to ShardingSphere-Proxy's shutdown script.
https://github.com/apache/shardingsphere/blob/24ddd96752447681fe04f0bac066f2ea77f5cb92/shardingsphere-distribution/shardingsphere-proxy-distribution/src/main/resources/bin/stop.sh#L25
The script find the Proxy's PID by directory. I'm happy to review a PR. Would you like to fix this?

But if change ProxyA name from `5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae ` to `Proxy1`;
change ProxyB name from `5aa2071bcb1d850b61b8e2b98ba77f2d12b683ae.bak` to `Proxy2`.
Do step 5-7,we can find proxy B still alive.
