检查现有版本JDK
# java -version 查找java相关文件并卸载
# rpm -qa|grep -i java
tzdata-java-2016f-.el6.noarch
java-1.8.-openjdk-headless-1.8.0.101-.b13.el6_8.x86_64 卸载openjdk1.

nameserver 10.143.22.118
nameserver 10.143.22.116 如果是海外服务器需要调整时区 查看系统默认的时区： [root@u05mix06 Asia]# ll /etc/localtime
lrwxrwxrwx root root May : /etc/localtime -> /usr/share/zoneinfo/America/Los_Angeles .修改时区
将Asia/shanghai-上海时区写入当前时区 # cp -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
cp: overwrite `/etc/localtime'? y
# cat /etc/sysconfig/clock
ZONE="America/Los_Angeles"
# centos7设置洛杉矶时间
timedatectl set-timezone America/Los_Angeles
提示是否覆盖,输入Y回车, 然后#date
查看时区和时间（CST,中国时区）
# date -R
Fri, May :: + crontab -e
加入如下任务：
* * * /usr/sbin/ntpdate -u us.pool.ntp.org | logger -t NTP 表示每天6点进行同步一次也可以选择us.ntp.org.cn 这个美国的时间同步服务器 将时间写入硬件

tcp监控

u04elk03 IN A 10.19.67.56 重启使配置生效
service named restart .修改文件句柄数限制
vim /etc/security/limits.conf * hard nofile
* soft nofile vim /etc/security/limits.d/-nproc.conf
删除这行
* soft nproc 编辑/etc/sysctl.conf
