我正在尝试设置 redis 以使用 Unix Socket。
我使用的是 Debian 原版安装/etc/redis/redis.conf，但在文件末尾添加了以下内容，基于此信息：
# create a unix domain socket to listen on
unixsocket /run/project/redis.sock
# set permissions for the socket
unixsocketperm 775
#requirepass passwordtouse
# bind 127.0.0.1
daemonize yes
# maximum memory allowed for redis
maxmemory 128Mb
我请求它在以下位置创建 unix 套接字/run/project/redis.socket：
# ll /run/project
total 4
drwxrwxrwx 2 michael www-data 100 Aug 29 16:32 .
drwxr-xr-x 21 root root 640 Aug 30 10:49 ..
我将用户添加redis到组www-data，又无奈地添加redis到组michael：
$ cat /etc/group | grep redis
www-data:x:33:michael,redis
michael:x:1000:www-data,redis
redis:x:119:
对我来说，我认为权限很好：
$ sudo -u redis touch /run/project/foo
$ ll /run/project/foo
-rw-r--r-- 1 redis redis 0 Aug 30 11:13 /run/project/foo
但是当我重新启动 redis 服务器时，它会失败：
$ systemctl restart redis-server.service
Job for redis-server.service failed because the control process exited with error code.
See "systemctl status redis-server.service" and "journalctl -xe" for details.
$ systemctl status redis-server.service

使用 Debian。安装redis有sudo apt install redis。
我试过此解决方案，但出现此错误：
$ sudo systemctl enable redis.service
Failed to enable unit: Refusing to operate on alias name or linked unit file: redis.service
更新：日志/配置文件的文件权限：
$ ll /var/lib/redis/dump.rdb
-rw-rw---- 1 redis redis 93 Aug 29 14:53 /var/lib/redis/dump.rdb
$ ll /etc/redis/redis.conf
-rw-r----- 1 redis redis 86461 Aug 30 11:11 /etc/redis/redis.conf
$ ll /var/log/redis/redis-server.log
-rw-rw---- 1 redis adm 22476 Aug 30 11:22 /var/log/redis/redis-server.log
关于停止然后重新运行的更新/usr/bin/redis-server：
$ systemctl stop redis-server.service
$ systemctl status redis-server.service

更新：尝试清除并重新安装 redis，但没有帮助。如果我使用默认配置启动它，则安装正常，并且运行：
# systemctl status redis-server.service

但是，当我添加以下内容以使用 unix 套接字时，它就停止工作：
unixsocket /run/project/redis.sock
# set permissions for the socket
unixsocketperm 775
requirepass passwordtouse
# bind 127.0.0.1
daemonize yes
# maximum memory allowed for redis
maxmemory 128Mb
答案1
我猜你搞错了必要的 redis 文件权限。请检查以下内容，确保 redis 可以访问文件/配置
redis-server.log(and associated logs files)
dump.rdb
Any config file which is read by redis process
更新：如果其他原因阻止 redis 启动，请尝试以下命令（根据您的设置更改路径），它将大多数时间向您显示确切的问题。
/usr/bin/redis-server /etc/redis/redis.conf
答案2
unixsocketperm 777
然后重启redis。
关于这个有很多信息，可以谷歌一下
它对我和其他人都有效。
我想我在这里发现了它......https://github.com/redis/node-redis/issues/204
