问题可能是因为配置的limit导致的。

1 [+ n+ f1 i( V5 Y- ]7 V; _
0 }& z6 J; J& V* H& c需要修改
vim /etc/security/limits.d/20-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.

1 B; [1 M) c# S5 n; ^*          soft    nproc     4096
( S( {( a( F: G! E1 l0 T! Hroot       soft    nproc     unlimited

修改成
" X7 ]# a4 }/ m& f" s: ]  z0 zvim /etc/security/limits.d/20-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.

故障现象 ：终端报错shell request failed on channel 0
故障原因 ：进程数达到限制，系统进程数太小，导致不能连接
$ P& |2 H  J. ]2 K  b4 D9 W解决方案 ：修改/etc/security/limits.d/20-nproc.conf中
" N, g" u0 y" G  D4 A) u$ m
soft nproc 4096
# W; \3 _0 L" Q6 T+ Cnproc的值和指定用户在/etc/security/limits.conf中nproc的限定值
