【已解决】设置redis的rdb文件的路径和文件名

redis crifan 945浏览 0评论

之前已经实现了基本的redis+celery去实现异步任务和周期任务了。

但是发现默认的redis会在当前项目根目录下生成

dump.rdb

文件,觉得不妥,想要:

指定redis的rdb文件的名字和位置

放到此处的runtime下面:

redis dump.rdb location

直接运行不行, 要cli进去后才能看到:

<code>[root@xx-general-01 robotDemo]# redis-cli CONFIG GET *

看到是:

dbfilename=dump.rdb

<code>(robotDemo-dwdcgdaG) [root@naturling-general-01 robotDemo]# echo "CONFIG GET *" | redis-cli | grep -e "dir" -e "dbfilename" -A1

redis – Where does dump.rdb belong? – Stack Overflow

还是要去找找redis.conf在哪,然后去修改配置文件才对

Ping Redis: How to get the rdb location, and config file location in redis.

参考:

linux – How do I load the dump.rdb file into redis? – Server Fault

去找到redis的conf后,去修改其中的dir

redis conf file

默认位置好像是:

或者是:

Where is the data directory in Redis? – Stack Overflow

看到此处的:

vim /etc/redis.conf

中是:

<code>dir /var/lib/redis
</code>

好像是:

此处服务器中,redis运行的数据库,并没有放到当前项目的文件夹下,而是默认放到了:

/var/lib/redis

所以去确认看看

结果并没有,而

/var/lib/redis/

也是空的:

<code>[root@xx-general-01 robotDemo]# ll

</code>

而再去看到:

<code>236 # The filename where to dump the DB
237 dbfilename dump.rdb
238  
239 # The working directory.
240 #
241 # The DB will be written inside this directory, with the filename specified
242 # above using the 'dbfilename' configuration directive.
243 #
244 # The Append Only File will also be created inside this directory.
245 #
246 # Note that you must specify a directory here, not a file name.
247 dir /var/lib/redis   
</code>

感觉是:

用supervisor去管理redis后:

<code>[program:redis]
directory=/xxx/robotDemo
command=/usr/bin/redis-server
</code>

使得working directory变成了当前项目根目录了:

/xxx/robotDemo

从而导致,在当前文件夹下生成了dump.rdb

所以问题好像转为:

redis在被supervisor管理后,通过directory切换了工作目录的问题了

如何在这种情况下,设置redis的工作目录

supervisor manage redis working directory

那是否可以通过此处运行redis-server时,在命令行中指定dir参数?

redis-server set dir

redis-server command line pass parameter dir

<code>redis-server  --dir /tmp
</code>

好像可以在命令行中指定dir参数的

去试试

之前也看过help:

<code>[root@xx-general-01 robotDemo]# redis-server --version
Redis server v=3.2.10 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=c8b45a0ec7dc67c6
[root@xx-general-01 robotDemo]# redis-server --help
Usage: ./redis-server [/path/to/redis.conf] [options]
       ./redis-server - (read config from stdin)
       ./redis-server -v or --version
       ./redis-server -h or --help
       ./redis-server --test-memory &lt;megabytes&gt;

Examples:
       ./redis-server (run the server with default conf)
       ./redis-server /etc/redis/6379.conf
       ./redis-server --port 7777
       ./redis-server --port 7777 --slaveof 127.0.0.1 8888
       ./redis-server /etc/myredis.conf --loglevel verbose

Sentinel mode:
       ./redis-server /etc/sentinel.conf --sentinel
</code>

中的:

<code>./redis-server - (read config from stdin)
</code>

但是不确定如何传递参数

去试试

<code>command=/usr/bin/redis-server /etc/redis.conf --dir /root/naturling_20180101/web/server/robotDemo/runtime
</code>

结果,

(由于更新了supervisor的配置,所以要先去:

<code>supervisorctl reload
supervisorctl start all
</code>

就可以了:

<code>[root@xx-general-01 robotDemo]# pwd
/xxxserver/robotDemo
[root@xx-general-01 robotDemo]# ll

-rw-r--r-- 1 root root   184 May 25 17:36 dump.rdb
[root@xx-general-01 robotDemo]#
</code>

【总结】

此处,是supervisor去管理redis的进程的,之前配置是:

<code>[program:redis]
directory=/root/naturling_20180101/web/server/robotDemo
command=/usr/bin/redis-server
</code>

对应的redis的配置是:

/etc/redis.conf

<code>236 # The filename where to dump the DB
237 dbfilename dump.rdb
238  
239 # The working directory.
240 #
241 # The DB will be written inside this directory, with the filename specified
242 # above using the 'dbfilename' configuration directive.
243 #
244 # The Append Only File will also be created inside this directory.
245 #
246 # Note that you must specify a directory here, not a file name.
247 dir /var/lib/redis  
</code>

而此处dump.rdb却存在项目的根目录下了:

/xxxserver/robotDemo

而原因:

可能是:

由于用supervisor去管理,且redis启动之前,切换到了

directory设置的,当前项目跟目录了:

/xxx/robotDemo

导致此处

之前redis设置的:

<code>dir /var/lib/redis
</code>

的路径没有用了。

而此处想要更改dump.rdb的路径的话,最终是:

通过命令行的方式给redis-server去传递dir参数,具体写法是:

<code>command=/usr/bin/redis-server /etc/redis.conf --dir /xxx/robotDemo/runtime
</code>

即可达到自己的目的:

把redis的dump.rdb,放到当前项目下的runtime目录中。
