jedis无法连接到redis服务端

2、分析原因

a、通过图形化redis端先尝试连接，发现也连接不上，报错密码错误，而实际我输入的密码是正确的

b、通过测试程序直接连接，也无法连接，报出上述错误

c、于是怀疑redis.conf配置文件的配置bind 的ip地址写死了本地地址

d、在linux状态下打开redis.conf果然，bind的参数配置是127.0.0.1

# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1

3、解决方案

把bind 的配置项注释

# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#bind 127.0.0.1

问题得到解决

4、注意：当前我的redis服务端设置的密码访问

如果没设置密码的话，通过以上处理，还是连接不上，可尝试一下操作

# By default protected mode is enabled. You should disable it only if
# you are sure you want clients from other hosts to connect to Redis
# even if no authentication is configured, nor a specific set of interfaces
# are explicitly listed using the "bind" directive.
#protected-mode yes

注释 保护模式，之后重启

、若还是不行、可注释一下配置

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
#daemonize yes

该项配置 Redis默认不是以守护进程的方式运行，可以通过该配置项修改，使用yes启用守护进程，设置为no

5、最后重启redis-server
