解決

linux下pam子產品是進行使用者認證管理的，系統開機後，使用者登陸之前先配置好使用者session

即能我多少個終端同時連接配接，密碼強度怎樣，是否過期，哪些使用者可以登陸圖檔界面等等

看報錯我們可以知道pam啟動失敗是由pam_limits下一個檔案沒有找到引起的：

pam_limits(systemd-user:session): cannot read settings from /etc/security/limits.d/clickhouse.conf: No such file or directory
           

進入這個目錄，發現它是一個軟連結，但是它所指向的軟連結根本不存在

把這個軟連結删了，然後重新開機伺服器問題解決

i75930# cd /etc/security/limits.d/
i75930# ll
lrwxrwxrwx root root 55 Feb 16 10:55 clickhouse.conf -> /opt/workspace/github/myconf/clickhouse/clickhouse.conf
i75930# cat clickhouse.conf
cat: clickhouse.conf: No such file or directory
i75930# cd /opt/workspace/github/myconf
