Git- How to kill ssh-agent properly on Linux
提问by Eric Wang
I am using git on linux, when pushing to gitlab, sometimes it either stuck at:
我在 linux 上使用 git，当推送到 gitlab 时，有时它会卡在：
debug1: Connecting to gitlab.com [52.167.219.168] port 22.
debug1：连接到 gitlab.com [52.167.219.168] 端口 22。
or
或者
debug1: client_input_channel_req: channel 0 rtype [email protected] reply 1
debug3: send packet: type 100
debug1：client_input_channel_req：通道 0 rtype [email protected] 回复 1
debug3：发送数据包：类型 100
Seems restarting linux could solve it, but no body like to reboot machines. So, I am trying to kill ssh-agent process, then restart it.
似乎重新启动 linux 可以解决它，但没有人喜欢重新启动机器。所以，我试图杀死 ssh-agent 进程，然后重新启动它。
But the process is always defunctafter kill, and then I can't use git via ssh at all, so is there any way to restart the ssh-agent, or solve the issue described above without restarting the machine?
但是进程总是defunct在kill之后，然后我根本无法通过ssh使用git，那么有没有办法重新启动ssh-agent，或者在不重新启动机器的情况下解决上述问题？
@Update
@更新
The ssh keys that I use include key phrase, which I would input on first use of a ssh key.
我使用的 ssh 密钥包括关键短语，我会在第一次使用 ssh 密钥时输入它。
The issue usually occurs after I bring the Linux desktop back from sleep, thus the network is reconnected, not sure whether this matters?
该问题通常发生在我将 Linux 桌面从睡眠状态恢复后，从而重新连接网络后，不确定这是否重要？
Again, does any one knows how to kill or restart a ssh-agentagent, without making it become defunct?
再一次，有没有人知道如何杀死或重新启动ssh-agent代理，而不会使它变成defunct？

You can try this bash script to terminate the SSH agent:
您可以尝试使用此 bash 脚本来终止 SSH 代理：
#!/bin/bash
## in .bash_profile
SSHAGENT=`which ssh-agent`
SSHAGENTARGS="-s"
if [ -z "$SSH_AUTH_SOCK" -a -x "$SSHAGENT" ]; then
eval `$SSHAGENT $SSHAGENTARGS`
trap "kill $SSH_AGENT_PID" 0
fi
## in .logout
if [ ${SSH_AGENT_PID+1} == 1 ]; then
ssh-add -D
ssh-agent -k > /dev/null 2>&1
unset SSH_AGENT_PID
unset SSH_AUTH_SOCK
fi

It shows defunctprobably because its parent process is still monitoring it, so it's not removed from the process table. It's not a big deal, the process is killed. Just start a new ssh-agent:
它显示defunct可能是因为它的父进程仍在监视它，所以它没有从进程表中删除。没什么大不了的，进程被杀死了。只需启动一个新的 ssh-agent：
eval $(ssh-agent)
ssh-add
