vi /etc/pam.d/common-session-noninteractive文件结尾附件找到 session required pam_unix.so 前面加上： session [success=1 default=ignore] pam_succeed_if.so service in cron quiet use_uid 保存。service cron restart
查看初始内存free -m切换至内存目录cd /dev/shm进行数据写入，标识 count=1000 为写入1000M，这里在服务商提供的标识数据内，自行进行数据增长dd if=/dev/zero of=./memtest bs=1M count=1000完成后，执行删除rm ./memtest

安装php的模块有两种方式：一、重新编译php，加上--with-gettext二、动态安装现在说下第二个动态安装1、下载同版本的php原包，解压后进入ext目录，目录下便是模块2、进入gettext目录下执行：/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-config（以上两个命令的路径根据自己系统情况而定）makemake install3、在php.ini里添加上gettext.soextension = "gettext.so"重启php即可
