可以看到监听的是tcp的ipv6的端口，所以需要配置ipv4
[root@zjj101 2m-2s-async]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 1224/mysqld tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 942/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1106/master tcp6 0 0 :::9876 :::* LISTEN 78614/java tcp6 0 0 :::22 :::* LISTEN 942/sshd tcp6 0 0 ::1:25 :::* LISTEN 1106/master修改配置文件
root@zjj101 2m-2s-async]# vi /usr/lib/sysctl.d//00-system.conf
00-system.conf 文件添加内容: net.ipv4.ip_forward = 1 ,然后 esc !wq 保存
说明:
net.ipv4.ip_forward 等于0表示不开启，为1表示开启。
00-system.conf 文件内容:
# Kernel sysctl configuration file # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Disable netfilter on bridges. net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 # 启用ip转发功能 net.ipv4.ip_forward = 1重启网络服务
命令: systemctl restart network
# 重启服务 [root@zjj101 2m-2s-async]# systemctl restart network # 查看配置是否生效,如果返回为“net.ipv4.ip_forward = 1”则表示成功 [root@zjj101 2m-2s-async]# sysctl net.ipv4.ip_forward net.ipv4.ip_forward = 1验证效果
此时访问一下, 我这边发现可以访问了, 即使 虚拟机再次挂起,再恢复, 也能访问了,
如果还不能访问怎么办?重启Docker里面的container
# 查看docker container ,发现两个都是Exited 状态,这不正常,下面开始重启 [root@zjj101 2m-2s-async]# docker ps -a ConTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8910b880038a styletang/rocketmq-console-ng "sh -c 'java $JAVA_O…" 2 days ago Exited (137) 2 minutes ago gifted_johnson e827d21c2efe uifd/ui-for-docker "/ui-for-docker" 2 days ago Exited (2) 2 minutes ago docker-web # 重启docker ConTAINER ID 为 8910b880038a 的 ConTAINER [root@zjj101 2m-2s-async]# docker restart 8910b880038a 8910b880038a # 重启docker ConTAINER ID 为 e827d21c2efe的 CONTAINER [root@zjj101 2m-2s-async]# docker restart e827d21c2efe e827d21c2efe
上面步骤做完了,不出意外基本就可以访问了.
