如何开展实验

先看完前一篇的《历史遗留错误解决》, 再看本篇, 不然你会感到举步维艰...

实验开始前的准备工作

Note

每次远程登录进一个服务器，都要对它做这些操作 🌶️

启动 mongodb:

Bash
1
2
sudo systemctl start mongod
sudo systemctl enable mongod

创建虚拟接口 ogstun:

Bash
1
2
3
4
sudo ip tuntap add name ogstun mode tun
sudo ip addr add 10.45.0.1/16 dev ogstun
sudo ip addr add 2001:db8:cafe::1/48 dev ogstun
sudo ip link set ogstun up

网络设置:

启用转发并添加 NAT 规则

Bash
1
2
3
4
sudo sysctl -w net.ipv4.ip_forward=1
sudo sysctl -w net.ipv6.conf.all.forwarding=1
sudo iptables -t nat -A POSTROUTING -s 10.45.0.0/16 ! -o ogstun -j MASQUERADE
sudo ip6tables -t nat -A POSTROUTING -s 2001:db8:cafe::/48 ! -o ogstun -j MASQUERADE

正确配置防火墙

Bash
1
sudo ufw disable

清理数据库:

Bash

mongosh
> use open5gs
switched to db open5gs
> db.subscribers.find()  ### Check the test subscriber
> db.subscribers.drop()  ### Remove all subscriber
> db.subscribers.find()  ### Check that all subscribers are empty

ps -ef | grep open5gs
sudo pkill -9 open5gs-mmed

sudo pkill -9 open5gs-smfd

sudo pkill -9 open5gs-seppd
sudo pkill -9 open5gs-ausfd
sudo pkill -9 open5gs-udmd
sudo pkill -9 open5gs-pcfd
sudo pkill -9 open5gs-nssfd
sudo pkill -9 open5gs-bsfd
sudo pkill -9 open5gs-udrd
ps?

ps -ef:

  • -e: 显示所有进程 (不仅是当前用户的)
  • -f: 以全格式显示进程信息，包括进程ID、父进程ID、CPU使用率、内存使用率

ps -a:

  • -a: 显示所有与当前终端会话相关的进程 (仅当前用户)

实验预热: 测试基础模块

测试: 构建成功否

Bash
1
2
3
4
cd build
./tests/registration/registration ## 5G Core Only
./tests/attach/attach ## EPC Only
meson test -v

必须要全部通过才可以，不能有任何一个部件出现闪失

Standard Output

alt text

测试: 安装成功否

Bash
1
ninja install

这一步基本上都没啥问题

测试: 各模块正常工作否

./install/bin/open5gs-sgwcd
./install/bin/open5gs-sgwud
./install/bin/open5gs-hssd
./install/bin/open5gs-pcrfd

必须要全部通过才可以, 每一个指令运行后都会一直执行，需要 ctrl+c 退出

这里给出每一个实例通过的logging msg, 便于读者判断该组件是否正常工作 👀

./build/tests/app/5gc

这条指令相当于一键测试(按顺序)了上述所有指令

但是不推荐用，因为单元测试更有利于看出到底是谁出了问题
