Acabei de instalar o tmux na minha máquina do CentOS 7, mas encontrei um problema desconcertante. Sempre que tento tentar iniciar uma sessão usando tmux ou tmux new -s session-name , ela gera uma sequência aleatória de caracteres no meu prompt e falha ao iniciar.
$ tmux
$ 1;2c
Eu não tenho ideia do que fazer com isso.
Minha configuração para o tmux está localizada em ~/.tmux.conf e está configurada da seguinte maneira.
setw -g mode-keys vi
# 12 hour clock
set-window-option -g clock-mode-style 12
# reload tmux.conf
bind r source-file ~/.tmux.conf \; display-message " ✱ ~/.tmux.conf is reloaded"
Eu também notei que alguns logs de erro foram gerados e são os seguintes.

Algumas das coisas neste log foram de uma versão anterior do meu .tmux.conf .
Alguma idéia?
Depois de ler a resposta do @jasonwryan, eu li na página do Sourceforge tmux e leia sobre a configuração do ambiente TERM sendo um problema em potencial.
Meu valor atual para $ TERM foi o seguinte:
$ echo $TERM
xterm-256color
Eu tentei executar os seguintes comandos para tentar alterá-lo.
$ export TERM=screen
$ tmux
$ echo $TERM
screen
Depois de obter os mesmos resultados de antes, reexportei meu valor $ TERM para xterm-256color .
Executando tmux sessões como o usuário root funciona bem; no entanto, usar tmux como qualquer usuário privilegiado sempre resultará nos problemas acima.
Eu também tive esse problema com o CentOS 7 e o binário tmux incluído. Acontece que eu tive que colocar meu usuário no grupo tty:
# /etc/group
tty:x:5:<username>
Eu tive que fazer isso, mesmo que minhas permissões ptmx parecessem assim:
crw-rw-rw- 1 root tty 5, 2 Dec 9 23:17 /dev/ptmx
Os vários comentários sobre a configuração TERM , etc., não parecem resolver o problema real.
A explicação mais provável é um problema com permissões que impede que tmux abra a conexão do pseudo-terminal. Por exemplo, alguém pode ter feito um chmod ou chown que quebrou o programa. Você pode ver se esse é o caso observando os resultados de strace , por exemplo,
TERM=xterm-256color script -c "strace -fo strace.out -s 2048 tmux -v"

Uma falha para o mestre "/ dev / ptmx" ou o escravo "/ dev / pts / xx " pararia tmux .
O log do servidor mostra que ele morre imediatamente depois de gerar um processo, que no código-fonte é o ponto em que ele começa a abrir o pseudo-terminal, por exemplo, (citando window.c in tmux 1.8):
A seguinte mensagem do servidor vem de session_destroy (citando de session.c ):
que é chamado dessa função em server.c :
Quando você executa strace , pode ver qual sinal está sendo processado.
Os caracteres inesperados são da inicialização normal feita por tmux . Parte disso pede ao terminal que tipo é, usando "\ 033 [c" (veja Sequências de Controle do XTerm para uma explicação disso). Em uma inicialização normal, tmux envia várias seqüências de escape. Este aqui pede uma resposta, e quando a resposta chega, tmux não está mais ouvindo, e simplesmente ecoa em seu shell.
Você obteria essa resposta específica para um VT100 regular.
Por que vale a pena, aqui está uma renderização visível da inicialização, em que \E é 3 :
Tive o mesmo problema no mac. O problema foi da linha de configuração da área de transferência:
set-option -g default-command "reattach-to-user-namespace -l zsh"
O problema foi resolvido ao executar no terminal:
brew install reattach-to-user-namespace
Eu tive o mesmo problema no meu CentOS 7 VPS e resolvi isso agora.
Eu tinha instalado o tmux antes por: yum install tmux
Depois eu removo e instalo por source code . Então eu tenho o mesmo problema que você.
Percebi que acabei de instalar muitas bibliotecas, então talvez eu devesse reboot o servidor.
Então eu reiniciei o servidor, o problema foi embora !!!
Meu problema foi com as más permissões do arquivo / dev / ptmx (0600). Quando eu mudei para 0666 como é menção no homem ptmx, o tmux não tem nenhum problema para iniciar.
Antes de fazer qualquer alteração, tente remover os diretórios / tmp / tmux- * Certifique-se de que isso não afete os usuários atualmente conectados.
