Nginx安装

  242  05/12/21 11:37:00 wget http://nginx.org/download/nginx-1.16.1.tar.gz
  243  05/12/21 11:38:14 tar -xvf nginx-1.16.1.tar.gz
  244  05/12/21 11:38:22 ls
  245  05/12/21 11:39:21 cd /opt/Nginx
  246  05/12/21 11:39:26 mkdir Nginx-1.16.1_install
  247  05/12/21 11:39:31 cd nginx-1.16.1
  248  05/12/21 11:39:47 ls
  249  05/12/21 11:39:50 ./configure --prefix=/opt/Nginx/Nginx-1.16.1_install
  250  05/12/21 11:39:59 cd ..
  251  05/12/21 11:40:00 ls
  252  05/12/21 11:40:02 ./configure --prefix=/opt/Nginx/Nginx-1.16.1_install
  253  05/12/21 11:40:20 cd nginx-1.16.1
  254  05/12/21 11:40:23 ./configure --prefix=/opt/Nginx/Nginx-1.16.1_install
  255  05/12/21 11:40:36 make
  256  05/12/21 11:40:57 make install
  257  05/12/21 11:41:05 make install
  258  05/12/21 11:41:11 ls
  259  05/12/21 11:41:21 cd conf
  260  05/12/21 11:41:22 ls
  261  05/12/21 11:41:30 vim nginx.conf

Consul安装启动

1.下载consul_0.7.5_linux_amd64.zip

wget https://releases.hashicorp.com/consul/0.7.5/consul_0.7.5_linux_amd64.zip

2.解压consul_0.7.5_linux_amd64.zip

unzip consul_0.7.5_linux_amd64.zip

3. 后台启动
nohup ./consul agent -dev -client 0.0.0.0 -ui &

4. 查看端口占用情况
netstat -anp|grep 8500

Docker环境安装

一、rabbitmq

如果没有镜像直接run会自动拉取镜像，不指定版本会拉取最新版本

docker run -d --hostname my-rabbit --name rabbit -p 15672:15672 -p 5672:5672 rabbitmq:management

安装后测试链接
http://ip:15672

二、ferryboatman/mysql:2.0.0

docker pull ferryboatman/mysql:2.0.0

docker run -itd --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=ferryboatman ferryboatman/mysql:2.0.0

三、ferryboatman/zipkin:2.0.0

docker pull ferryboatman/zipkin:2.0.0

docker run --name zipkin -d -p 9411:9411 ferryboatman/zipkin:2.0.0

安装后测试链接
http://ip/zipkin/

四、fastdfs

自己的打包镜像有问题，还是使用网上找到的一个惊喜吧

[root@VM-16-17-centos ~]# docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=121.5.129.126 -e WEB_PORT=80 -v /usr/local/fastdfs:/var/local/fdfs registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs
40df4c0ed24c1c434119afdf663abedf1d64f83aafe9f9722ecdd8ee38dd671a
[root@VM-16-17-centos ~]# docker exec -it fastdfs /bin/bash
bash-4.4# echo "Hello FastDFS!">index.html
bash-4.4# fdfs_test /etc/fdfs/client.conf upload index.html
This is FastDFS client test program v5.12

五、ferryboatman/mongo:2.0.0

docker pull ferryboatman/mongo:2.0.0

docker run -itd --name mongo -p 27017:27017 ferryboatman/mongo:2.0.0 --auth
//进入容器
docker exec -it 9ff342ce96fd mongo admin

// 创建用户
> db.createUser({ user: 'admin', pwd: 'hcz123456', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });
Successfully added user: {
	"user" : "admin",
	"roles" : [
		{
			"role" : "userAdminAnyDatabase",
			"db" : "admin"
		}
	]
}

> db.auth("admin","hcz123456")
1
> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB

六、redis

docker pull redis

 docker run --name redis -p 6379:6379  -d redis:latest

示例：pandas 是基于NumPy 的一种工具，该工具是为了解决数据分析任务而创建的。

二、Linux其他相关命令

1.命令

代码如下（示例）：

 // 查看内存占用 20个
[root@VM-16-17-centos ~]# ps auxw|head -1;ps auxw|sort -rn -k4|head -20

// 启动命令  后台启动，日志文件输入到logs.txt
[root@VM-16-17-centos ~]# nohup java -jar Ferry-consul.jar >logs.txt &

// 启动docker
[root@VM-16-17-centos ~]# systemctl start docker

// 显示运行在系统上的所有进程
[root@VM-16-17-centos ~]# ps -ef
 
// 进入容器acbce180dfa3内部
[root@VM-16-17-centos ~]# docker exec -it acbce180dfa3 /bin/bash

// 查看后台运行的进程 
[root@VM-16-17-centos ~]# jobs 

// 排查日志相关
// 后50行日志
cat -n info-appender.log | tail -n 50
//关键字查看后20行
cat -n info-appender.log | grep "大方" -A 20
//关键字查看前20行
cat -n info-appender.log | grep "大方" -B 20
//关键字查看前后20行
cat -n info-appender.log | grep "大方" -C 20

//从第10行开始，显示20行
tail -n +10表示查询10行之后的日志
//head -n 20 则表示在前面的查询结果里再查前20条记录
cat -n info-appender.log |tail -n +10|head -n 20

//时间点日志
grep '2021-11-18 11:36:20' info-appender.log

sed -n '/2021-11-18 11:36:12/,/2021-11-18 11:36:36/p' info-appender.log
