tmux - tmux - 连接失败：连接被拒绝

问题描述

我想在 rhel 7 上使用 tmux。我在这台机器上没有 root 权限，所以我按照以下步骤从源代码构建它：https ://jdhao.github.io/2018/10/16/tmux_build_without_root_priviledge/ 。

我已经在本地构建并安装了 libevent 2.1.8、ncurses 6.1 和 tmux 2.8。它们都安装在 ~/local 中。

当我启动 tmux 时，它没有启动。我得到的信息是：

[退出]

我再次使用选项 -vv 开始，我得到了日志。

在服务器端，我得到：

在客户端：

我唯一能看到的是客户端无法连接套接字。我没有注意到服务器端有任何错误。

我会知道是什么阻止了 tmux 正常启动。

标签： tmux

解决方案

详细分析表明，tmux 使用的默认 shell 在我的环境中退出并出现错误。

我通过强制使用另一个外壳解决了问题。我把它放在 .tmux.conf:set-option -g default-shell /bin/zsh中。
