\o/ All tests passed without errors!

Cleanup: may take some time... OK

测试最后一步等待时间有点长~~~我还以为卡了

如果出现进入Redis连接拒绝,请先确定服务是否启动了

gulugu@Dell:~$ redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> 

作为后台进程启动服务 redis-server &

[14496] 02 Aug 16:46:52.438 * The server is now ready to accept connections on port 6379

正常访问:

gulugulu@Dell:~$ redis-cli
127.0.0.1:6379> 

因为没有添加开机启动,所以开机的时候我执行启动服务,发现端口并不是6379,所以还是会报连接拒绝,我尝试这样去绑定端口6379

gg@Dell:~$ redis-server --port 6379 --daemonize yes
gg@Dell:~$ redis-cli -p 6379
127.0.0.1:6379> exit
