tomcat运行blog失败 redis服务启动失败

照着老师的配置最后tomcat还是打不开blog这个应用

11月 15 13:49:14 luomin systemd[1]: Failed to start Redis In-Memory Data Store.
11月 15 13:49:14 luomin systemd[1]: Unit redis.service entered failed state.
11月 15 13:49:14 luomin systemd[1]: redis.service failed.

11月 15 13:52:37 luomin systemd[1]: redis.service: main process exited, code=exited, status=217/USER

排查半天发现redis启动失败

[root@luomin redis]# ./redis-server redis.conf

我的配置文件

[root@luomin classes]# cat application.yaml 
server:
  port: 9000
  session:
    timeout: 3600

  freemarker:
    cache: false

telnet测试失败连不上三台机子都试了都是连接失败

[root@luomin classes]# telnet 192.168.1.80 6379
Trying 192.168.1.80...
telnet: connect to address 192.168.1.80: Connection refused

但是tel127.0.0.1可以

[root@luomin classes]# telnet 127.0.0.1 6379
Trying 127.0.0.1...
Connected to 127.0.0.1.

查看我的redis.conf

bind 192.168.1.80 127.0.0.1
protected-mode yes
port 6379

我在排查过程中发现无法使用

sudo systemctl restart redis.service

排查后添加了如下配置文件

[Unit]
Description=Redis In-Memory Data Store
After=network.target

[Service]
User=root
Group=root
ExecStart=/usr/redis/redis-server /usr/redis/redis.conf
ExecStop=/bin/kill -s QUIT $MAINPID
Restart=always

[Install]
WantedBy=multi-user.target

上述文件默认的User=redis Group=redis，这种情况redis起不来
还是这个错误

redis.service: main process exited, code=exited, status=217/USER

所以我改成了root 和 root ，ExecStart=/usr/redis/redis-server /usr/redis/redis.conf 也是视频里redis的默认安装路径

[root@luomin system]# cd /usr/redis/
[root@luomin redis]# ll
总用量 16964
-rwxr-xr-x. 1 root root 4366960 11月 14 18:10 redis-benchmark
-rwxr-xr-x. 1 root root 4808056 11月 14 18:10 redis-cli
-rw-r--r--. 1 root root   61811 11月 15 14:30 redis.conf
-rwxr-xr-x. 1 root root 8125376 11月 14 18:10 redis-server
[root@luomin redis]# pwd
/usr/redis

老师麻烦帮忙看下哪里出了问题搞了一天了
