Unable to output influxd.log.

When I deploy influx:1.8 and 1.11 , I want to mount the log files(access.log and influxdb.log) to local directory. I tried many ways however in vain. But I did successfully output access.log and mount it. I am sure that the the problem is in the configration. Because I created a file(test.log) inside the contianer at `/var/log/influxdb/` and I can see the test.log in my host machine.

And I did find a way to achieve this function but its not recommended:
1. Get inside the container `docker exec -it influxdb bash`
2. `influxd > /var/log/influxdb/influxdb.log 2>&1 &`
3. After this operation , the influxdb.log is able to be accessed both in the container and host machine.

This is my deploy code:

### deploy code

```
docker run -d \
--name influxdb \
-p 8086:8086 \
-v /data/soft/influxdb1.8/data:/var/lib/influxdb \
-v /data/soft/influxdb1.8/config/influxdb.conf:/etc/influxdb/influxdb.conf \
-v /data/soft/influxdb1.8/log:/var/log/influxdb \
influxdb:1.8 -config /etc/influxdb/influxdb.conf
```

### ways I tried
These are the ways I tried:

1. change infuxdb.conf：
```
reporting-disabled = true

[meta]
dir = "/var/lib/influxdb/meta"
retention-autocreate = true
logging-enabled = true

[data]
dir = "/var/lib/influxdb/data"
wal-dir = "/var/lib/influxdb/wal"
query-log-enabled = true
cache-max-memory-size = "1g"
cache-snapshot-memory-size = "25m"
cache-snapshot-write-cold-duration = "10m"
compact-full-write-cold-duration = "4h"
max-series-per-database = 1000000
max-values-per-tag = 100000

[http]
enabled = true
bind-address = ":8086"
auth-enabled = false
log-enabled = true
access-log-path = "/var/log/influxdb/access.log"

[logging]
level = "info"
file = "/var/log/influxdb/influxdb.log"

[retention]
enabled = true
check-interval = "30m"

```
2. give all priviledges to the directories

Start with the supplied docker run command and mounted influxdb.conf, then reproduce the configuration using the influxdb:1.8 image. Compare the working access.log setting with the logging.file setting and check whether influxdb.log is created in the mounted /var/log/influxdb directory. Done means the daemon writes influxdb.log there without manually starting a second process.
