The VT102 was a member of the “second generation” of the VT100 family.
The original VT100 was sold with a number of options that could be inserted
into the box. The most significant was the AVO, or Advanced Video Option,
which was pretty much just extra memory. The base VT100 supported a 24×80
mode and a 14×132 mode. It supported normal text plus one video attribute,
which could be either underlining or reverse-video – which one you got
depended on whether you selected an underline or box cursor. AVO gave you
24×132 mode and the full four video attributes (underline, reverse, bold,
blink). The VT100 also had a modem control option, providing extra RS-232
signals.
The VT102 was a closed system (no options) which provided the equivalent of
a VT100 plus AVO plus (I think) modem control. It also added one or two
new commands – if I remember correctly, “Insert Line” (open a new line,
scroll stuff below it down) and “Delete Line”, and perhaps “Insert” and
“Delete Character in Line”.
DEC many years ago *defined* “VT100 compatibility” as “equivalent to a
VT102”. All subsequent DEC products that claimed VT100 compatibility
actually supported the full 24×132 display mode, four video attributes, and
the additional commands. (Modem control is a separate issue – “VT100
compatibility” is usually taken to refer only to *software* compatibility.)
As far as I know, the industry has pretty much followed DEC’s definition,
except that many terminal emulators are incapable of properly supporting
the 132-wide mode due to limitations of their displays.
There is absolutely no difference between the keypads of VT100’s and
VT102’s.

node的typescript的常用操作
1.安装node版本，建议选择v8.11.3版本。
https://nodejs.org/dist/v8.11.3/node-v8.11.3-x64.msi
2.安装visual studio code，选择最新版。
【npm的所有命令，请不要powershell中执行，目前还不知道为什么在本人环境发现在执行npm config set注册下载源时，会出错，且错得很离谱。故需要用cmd.exe来解决。】
3.安装全局组件。
npm install -g typescript
npm install -g pm2
npm install -g ts-node
4.安装本地组件
npm install
5.如果觉得安装有问题，可以直接清理npm缓存及组件。

mongo分片及副本集搭建例子
https://github.com/senssei/mongo-cluster-docker
基于上面仓库，改造了一个副本集。
https://github.com/kxtry/mongo-cluster-docker
1.副本集docker-compose脚本

3.与docker-compose.yml相同子目录下的./scripts/setup.sh脚本
#!/bin/bash
mongodb1="${MONGO1}"
mongodb2="${MONGO2}"
mongodb3="${MONGO3}"
echo "Waiting for startup.."
until mongo --host ${mongodb1} --eval 'quit(db.runCommand({ ping: 1 }).ok ? 0 : 2)' &>/dev/null; do
printf '.'
sleep 1
done
echo "Started.."
echo setup.sh time now: `date +"%T" `
mongo --host ${mongodb1} <
3.构建脚本build_cluster.sh
#!/bin/sh
path_current=`pwd`
path_script=$(cd "$(dirname "$0")"; pwd)
mode=$1
extern_ip=$2
case "$mode" in
'build')
if [ -f $path_script/docker-compose.yml ]; then
echo 'the docker-compose.yml had been exist. if you want to continue, remove it.'
exit 1
fi
/bin/cp $path_script/docker-compose.yml.template $path_script/docker-compose.yml && echo "$path_script/docker-compose.yml" | xargs /bin/sed -i "s#{{extern_ip}}#$extern_ip#g"
echo 'success to build the file.'
;;
*)

echo "Usage: $basename {build}{extern_ip}"
echo "---$basename build 192.168.10.104"

Dockerfile的CMD和ENTRYPOINT的关系
以下示范，表示该形式下的CMD与ENTRYPOINT的关系。
CMD相当于应用程序的参数，ENTRYPOINT相当于应用的main入口或主程序入口。
FROM centos
CMD ["echo 'p222 in cmd'"] #传递给ENTRYPOINT的参数项。
ENTRYPOINT ["echo"] #应用入口，相当于程序的main函数
1.构建
docker build -t test .
2.执行以下指令执行默认的CMD命令。
docker run test
输出结果：
echo 'p222 in cmd'
3.修改程序输入参数
docker run test abct123
输出结果：
abct123
mongo的测试脚本
conn = new Mongo("mongodb://wps_credit:2f25da558f6e79c452a61bea4a8d762f@10.100.2.216:27017,10.100.2.217:27017,10.100.2.218/wps_credit?maxPoolSize=300&replicaSet=kae-mongo-test42");
db = conn.getDB("wps_credit");
var t1 = new Date();
printjson(db.getCollectionNames());
var t2 = new Date().getTime();
printjson(t1, t2, t2 - t1);
Telnet服务安装
yum install telnet-server -y
yum list|grep telnet
开启服务
systemctl start telnet.socket
