**解决：**

打开报错的文件，注释掉mcrypt\_module\_open相关的代码块，一共有两处。

[root@ldap1 ~]# vi /usr/share/phpldapadmin/lib/functions.php
    /*  第一段注释
            if (function_exists('mcrypt_module_open') && ! empty($data)) {
                    $td = mcrypt_module_open(MCRYPT_BLOWFISH,'',MCRYPT_MODE_ECB,'');
                    $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td),MCRYPT_DEV_URANDOM);
                    mcrypt_generic_init($td,substr($secret,0,mcrypt_enc_get_key_size($td)),$iv);
                    $encrypted_data = base64_encode(mcrypt_generic($td,$data));
                    mcrypt_generic_deinit($td);
    
                    return $encrypted_data;
            }
    */
    
            if (file_exists(LIBDIR.'blowfish.php'))
                    require_once LIBDIR.'blowfish.php';
            else
                    return $data;
    
    
    ...
    
    /* 第二段注释
            if (function_exists('mcrypt_module_open') && ! empty($encdata)) {
                    $td = mcrypt_module_open(MCRYPT_BLOWFISH,'',MCRYPT_MODE_ECB,'');
                    $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td),MCRYPT_DEV_URANDOM);
                    mcrypt_generic_init($td,substr($secret,0,mcrypt_enc_get_key_size($td)),$iv);
                    $decrypted_data = trim(mdecrypt_generic($td,base64_decode($encdata)));
                    mcrypt_generic_deinit($td);
    
                    return $decrypted_data;
            }
    */
    
            if (file_exists(LIBDIR.'blowfish.php'))
                    require_once LIBDIR.'blowfish.php';
            else
                    return $encdata;

重启httpd服务

[root@ldap1 ~]# systemctl restart httpd

再次打开网页，已经不报错了
