redis client连接数达到最大限制，redisclient
最近碰到reids客户端连接数达到1000，超过reids.confi里的
# Once the limit is reached Redis will close all the new connections sending
# an error 'max number of clients reached'.
## maxclients 10000
查看reids-cli里的client list 发现很多连接，使用client kill命令结束。因为数量多，要一个一个Kill比较麻烦
所以需要些个脚本批处理，后面附上脚本代码
主要原因是本地测试项目时候直接关闭后，redis 连接没有主动关闭。有这几个redis配置可以主动关闭
空闲的连接
# Close the connection after a client is idle for N seconds (0 to disable)
timeout 0
# On Linux, the specified value (in seconds) is the period used to send ACKs.
# Note that to close the connection the double of the time is needed.
# On other kernels the period depends on the kernel configuration.
#
# A reasonable value for this option is 300 seconds, which is the new
# Redis default starting with Redis 3.2.1.tcp-keepalive 300
这个主动连接客户端，但耗性能。
后面附上结束redis客户端脚本
