SSH到服务器创建用户出错

老陈73

这是怎么回事？
postgres@debian:/$ createuser ssssjk
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) n
createuser: 无法联接到数据库 postgres: could not connect to server: 没有那个文件或目录
        Is the server running locally and accepting
        connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

postgres@debian:/$ psql
psql: could not connect to server: 没有那个文件或目录
        Is the server running locally and accepting
        connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?


debian:/var/run/postgresql# ls -a
.  ..

没本

把createuser ssssjk改成
createuser ssssjk -hlocalhost -U<pg admin user>
注意把<pg admin user>替换成你的具有admin权限的用户名，-U后面不要跟空格

我把postgresql卸载后重装就正常了
估计还是安装系统是选择安装数据库服务器时系统有些东西没有自动安装上
