INTERNALERROR> def worker_internal_error(self, node, formatted_error):

报错中间错误内容详情

# 情况一
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot activate web view
# 情况二
selenium.common.exceptions.InvalidSessionIdException: Message: invalid session id

排查问题

主要原因在于启动selenium的Node容器时，没有指定--shm-size，shm 分区设置太小导致 share memory 不够

解决方法

docker启动Node容器时，指定--shm-size大小等2g，

# Node 与 Hub在同一个服务器上
docker run -d --net grid --shm-size="2g" -e SE_EVENT_BUS_HOST=selenium-hub -e SE_EVENT_BUS_PUBLISH_PORT=4442 -e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 selenium/node-chrome
# Node 与 Hub不在同一个服务器上，192.168.1.170是Hub服务器IP，192.168.1.72是Node服务器IP
docker run -d -p 5551:5551 --shm-size="2g" -e SE_EVENT_BUS_HOST=192.168.1.170 -e SE_EVENT_BUS_PUBLISH_PORT=4442 -e SE_EVENT_BUS_SUBSCRIBE_PORT=4443 -e SE_NODE_HOST=192.168.1.72 -e SE_NODE_PORT=5551 selenium/node-chrome

延伸--如何查看shm大小

查看shm需要进到容器里面才能看到，宿主机是看不到的

# 宿主机上运行df -h，并没有shm
[root@localhost ~]# df -h
