根据报错定位到一个错误栈:Caused by: redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect

应该是redis连接不上，确认配置(host、password、port、timeout等)没有问题之后检查逐步排查其他问题

1、先检查了redis状态

[root@master src]# ps -aux | grep redis
    root      11455  0.0  0.0 162396  7796 ?        Ssl  20:42   0:01 redis-server 127.0.0.1:6379
    root      58166  0.0  0.0 112828   988 pts/0    S+   21:19   0:00 grep --color=auto redis
    [root@master src]# netstat -nltp | grep redis
    tcp        0      0 127.0.0.1:6379          0.0.0.0:*               LISTEN      11455/redis-server
    [root@master src]# redis-cli
    127.0.0.1:6379>

redis正常状态且能正常使用

2、检查防火墙是否关闭或者是否放行redis端口(redis默认端口6379)

[root@master src]# systemctl status firewalld
    ● firewalld.service - firewalld - dynamic firewall daemon
       Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
       Active: inactive (dead)
         Docs: man:firewalld(1)
    [root@master src]#

防火墙为关闭状态  
3、查看redis配置里的保护模式是否关闭(redis3.2版本以上有这个属性)  
查看redis配置里的bind是否关闭

[root@master redis-6.0.8]# cat redis.conf | grep protect
    # Protected mode is a layer of security protection, in order to avoid that
    # When protected mode is on and if:
    # By default protected mode is enabled. You should disable it only if
    protected-mode yes
    # If the master is password protected (using the "requirepass" configuration
    # on the internet. It's just a protection layer against misuse of the instance.
    # So use the 'requirepass' option to protect your instance.
    [root@master redis-6.0.8] # cat redis.conf |grep bind
    # By default, if no "bind" configuration directive is specified, Redis listens
    # the "bind" configuration directive, followed by one or more IP addresses.
    # bind 192.168.1.100 10.0.0.1
    # bind 127.0.0.1 ::1
    # internet, binding to all the interfaces is dangerous and will expose the
    # following bind directive, that will force Redis to listen only into
    bind 127.0.0.1
    # 1) The server is not binding explicitly to a set of addresses using the
    #    "bind" directive.
    # are explicitly listed using the "bind" directive.

可以看到redis保护模式合bind 参数是开启的

*  将配置中的yes改为no
 *  将bind哪一行注释掉
 *  之后重新启动即可解决问题
