eggjs egg-ioredis 中使用lua 脚本 (redis lua 脚本的扫盲帖 )

$ redis-cli --eval path/to/redis.lua numberkeys KEYS[1] KEYS[2] , ARGV[1] ARGV[2] ...

path/to/redis.lua,是lua脚本的位置,也可以直接为脚本字符串。是一个Lua 5.1 script。
numberkeys ,指定后续参数有几个key。
KEYS[1] KEYS[2],是要操作的键,可以指定多个,在lua脚本中通过KEYS[1], KEYS[2]获取
ARGV[1] ARGV[2],参数,在lua脚本中通过ARGV[1], ARGV[2]获取。实例脚本 批量查询hash的值 hget 和切换db 以eggjs为例/**

2、查看防火墙所有开放的端口firewall-cmd --zone=public --list-ports
3.、关闭防火墙
如果要开放的端口太多,嫌麻烦,可以关闭防火墙,安全性自行评估systemctl stop firewalld.service
4、查看防火墙状态 firewall-cmd --state
5、查看监听的端口netstat -lnpt
PS:centos7默认没有 netstat 命令,需要安装 net-tools 工具,yum install -y net-tools
6、检查端口被哪个进程占用netstat -lnpt |grep 5672
7、查看进程的详细信息
ps 6832
8、中止进程
kill -9 6832 查看全部
firewall-cmd --zone=public --add-port=5672/tcp --permanent# 开放5672端口
firewall-cmd --zone=public --remove-port=5672/tcp --permanent#关闭5672端口
firewall-cmd --reload# 配置立即生效
