listening socket *:6379: bind: Address already in use
表示6379端口已经在使用（6379是redis默认的端口）

解决方法

1. 查找redis-server 的进程 （Process Status）

ps -ef | grep -i redis

结果如下：

xxx@xxx ~ % ps -ef | grep -i redis
  501  1496     1   0  1:02下午 ??         0:00.37 redis-server *:6379
  501  1697  1654   0  1:10下午 ttys001    0:00.00 grep -i redis

2. 杀死6379对应的进程

kill -9 1496 #每个人对应的会不一样

3. 重启redis-server

redis-server

结果如下：
