sshd restart 遇到错误 cat: /proc/sys/crypto/fips_enabled: No such file or directory

[root@li414-184 ~]# /etc/init.d/sshd restart
Stopping sshd:                                             [  OK  ]
cat: /proc/sys/crypto/fips_enabled: No such file or directory
/etc/init.d/sshd: line 50: [: too many arguments
Starting sshd:                                             [  OK  ]

解决如下

vi /etc/init.d/sshd


找到地50行：
if [ ! -s $RSA1_KEY -a `cat /proc/sys/crypto/fips_enabled` -eq 0 ]; then


修改为：
if [ ! -s "$RSA1_KEY" -a "'sysctl -n -e crypto.fips_enables'" = 0 ]; then
