3 启动客户端

redis-cli

127.0.0.1:6379> ping
PONG

4 检查 Redis 服务器系统进程

ps -aux|grep redis

ubuntu    @H_404_26@5617  @H_404_26@0.0  @H_404_26@0.7  @H_404_26@38856  @H_404_26@7884 pts/@H_404_26@0    Sl+  @H_404_26@12:@H_404_26@57   @H_404_26@0:@H_404_26@01 redis-server *:@H_404_26@6379

5 通过端口检查 Redis 服务器状态

netstat -nlt|grep 6379

tcp        @H_404_26@0      @H_404_26@0 @H_404_26@0.@H_404_26@0.@H_404_26@0.@H_404_26@0:@H_404_26@6379            @H_404_26@0.@H_404_26@0.@H_404_26@0.@H_404_26@0:*               LISTEN

6 通过启动命令检查 Redis 服务器状态

sudo /etc/init.d/redis-server status

redis-server is running
