但是无法访问
原因:
docker里面的host不能配置127.0.0.1 或者192.168.0.1 或则宿主机器将无法访问端口
修改配置文件—(涉及到的,需要外部访问的都需要修改)

修改好之后重启 docker里的服务

[root@ubuntu-10 open -falcon] # ./open-falcon restart transfer

查看端口的连接性

test @ubuntu-10: /tmp/bak $ telnet 10.0.10.103 8433
Trying 10.0.10.103...
Connected to 10.0.10.103.
Escape character is '^]' . #这就是ok的
|
好啦~ 可以连接成功。
补充:docker 镜像启动成功但是无法访问
解决办法:
vi /etc/sysctl.conf 或者
vi /usr/lib/sysctl.d/00-system.conf 添加如下代码:
1
|
net.ipv4.ip_forward=1
|
重启network服务
systemctl restart network 查看是否修改成功
sysctl net.ipv4.ip_forward 如果返回为“net.ipv4.ip_forward = 1”则表示成功了
以上为个人经验,希望能给大家一个参考,也希望大家多多支持服务器之家。如有错误或未考虑完全的地方,望不吝赐教。
