1、在centos7下搭建redis5，在启动redis节点时，一直启动不起来，查看log文件，报错信息如下：

4208:C 03 Mar 16:13:03.321 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
4208:C 03 Mar 16:13:03.322 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=4208, just started
4208:C 03 Mar 16:13:03.322 # Configuration loaded
4209:M 03 Mar 16:13:03.323 * Increased maximum number of open files to 10032 (it was originally set to 1024).
4209:M 03 Mar 16:13:03.323 # Creating Server TCP listening socket 114.67.72.240:7001: bind: Cannot assign requested address

2、执行命令

#  设置“open files”数量
ulimit -n 10032

3、如现设置"open files"数量后，节点还起不起来，修改节点目录下的redis.conf文件内容如下：

bind 192.168.1.21 

改为

bind 127.0.0.1
