Linux-Cent7.9 redis路径查找 | 删除redis所有缓存

查看redis端口命令

[root@VM-20-17-centos etc]# ps -ef|grep redis
redis     1257     1  0 Nov20 ?        00:02:06 /usr/bin/redis-server 0.0.0.0:6379
root      6340  6653  0 15:27 pts/0    00:00:00 grep --color=auto redis

发现redis-server对应端口为1257

查看redis对应的路径，并进入路径

[root@VM-20-17-centos etc]# ls -l /proc/1257/cwd
lrwxrwxrwx 1 redis redis 0 Nov 20 11:41 /proc/1257/cwd -> /etc
[root@VM-20-17-centos etc]# cd /etc

进入redis，执行操作

[root@VM-20-17-centos etc]# /bin/redis-cli # 进入redis
127.0.0.1:6379> dbsize  # 当看到127.0.0.1:6379就知道进入成功
(integer) 26
127.0.0.1:6379> flushall  # 清理缓存
OK
127.0.0.1:6379> dbsize  # 查看当前的缓存数量
(integer) 0
127.0.0.1:6379> keys * # key的个数
(empty list or set)
127.0.0.1:6379> exit # 退出redis

redis报错，无法持久化硬盘，临时解决方案

127.0.0.1:6379> flushall
