启动Docker，命令：systemctl start docker，然后加入开机启动，如下

[root@localhost ~]# systemctl start docker
[root@localhost ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

验证安装是否成功(有client和service两部分表示docker安装启动都成功了)

如何从远程主机上拷贝docker image到本地

1.以root身份在远程主机保存image到文件
docker save -o [filename] [image]
示例：
docker save -o aspnet.tar mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim

2.修改保存文件为任何人可读
chmod a+r [filename]

3.本地主机使用scp命令拷贝远程文件到本地
scp <username>@<ip>:<file> <local path>
示例:
scp test@192.168.1.2:/home/test/aspnet.tar /home/test
输入后会提示输入密码

4.本地从文件加载到docker image仓储
docker load<[filename]
示例
docker load<aspnet.tar

5. 使用docker images命令查看已导入的image
docker images

安装prometheus

安装 Prometheus Server

docker run -d -p 9090:9090 \
-v /root/prometheus.yml:/etc/prometheus/prometheus.yml \
--name prometheus \
--net=host \
prom/prometheus

global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093
      #
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"


scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
     - job_name: 'prometheus'
       static_configs:
       - targets: ['localhost:9090','localhost:9100','localhost:8080','192.168.28.18:8080','192.168.28.18:9100','192.168.28.19:8080','192.168.28.19:9100']

安装Node Exporte

docker run -d  \
-v "/proc:/host/proc" \
-v "/sys:/host/sys" \
-v "/:/rootfs" \
--net=host \
prom/node-exporter \
--path.procfs /host/proc \
--path.sysfs /host/sys \
--collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

Exporter

Prometheus 有很多现成的 Exporter，完整列表请参考 https://prometheus.io/docs/instrumenting/exporters/

安装altermanager

docker run -d -p 9090:9090 -v /etc/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml -v /etc/prometheus/rules/node_exporter_rule.yml:/etc/prometheus/rules/node_exporter_rule.yml -v /etc/prometheus/rules/jmx_exporter_rule.yml:/etc/prometheus/rules/jmx_exporter_rule.yml --name prometheus --net=host prom/prometheus

docker run -d -p 9093:9093 -v /etc/prometheus/alertmanager.yml:/etc/alertmanager/alertmanager.yml -v /etc/prometheus/wechat.tmpl:/etc/alertmanager/wechat.tmpl --name alertmanager prom/alertmanager

grafana安装

先普通启动，然后把配置文件导出来，修改配置文件，挂载到etc下

## 普通启动，挂载数据盘
docker run  -d --name grafana -p 3000:3000   -v /data/grafana:/var/lib/grafana  grafana/grafana

## 复制出配置文件
docker cp grafan:/etc/grafana/grafana.ini /data/grafana-data/etc/
## 修改配置文件，比如加上域名，比如修改端口为80，比如。。。


## kill重启
docker kill grafana
docker rm grafana
docker run --user root  -d --name grafana -p 3000:3000  -v /data/grafana-data/etc:/etc/grafana/ -v /data/grafana-data/grafana:/var/lib/grafana  grafana/grafana


docker run --user root  -d --name grafana -p 3000:3000  -v /data/opt/monitor/grafana-data/etc:/etc/grafana/ -v /data/opt/monitor/grafana-data/grafana:/var/lib/grafana  grafana/grafana

nginx监控

下载
wget http://nginx.org/download/nginx-1.20.1.tar.gz
wget https://github.com/vozlt/nginx-module-vts/archive/refs/tags/v0.2.0.tar.gz
解压 
tar -xzvf nginx-1.20.1.tar.gz
tar -xzvf v0.2.0.tar.gz && mv nginx-module-vts-0.1.12 nginx-1.20.1/

备份现有的nginx文件

cp -r /etc/nginx /etc/nginx_bak
cp /usr/sbin/nginx /usr/sbin/nginx_bak

安装依赖
yum -y install perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel python-devel gcc-c++   openssl-devel cmakepcre-develnanowget  gcc gcc-c++ ncurses-devel per
yum install gd gd-devel
yum install gperftools

编译
./configure --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-compat --with-debug --with-file-aio --with-google_perftools_module --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_degradation_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_image_filter_module=dynamic --with-http_mp4_module --with-http_perl_module=dynamic --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-http_xslt_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-stream_ssl_preread_module --with-threads --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E' --add-module=nginx-module-vts-0.2.0

上面完成后，继续输入：make -j8
禁止：千万不要继续输入“make install”，以免现在的nginx出现问题
以上完成后，会在objs目录下生成一个nginx文件，先验证：
./nginx -t
./nginx -V

以上成功后：
systemctl stop nginx
cp objs/nginx /usr/sbin/
systemctl start nginx
nginx -s reload

nginx 配置

http {
 
    vhost_traffic_status_zone;（添加）
    vhost_traffic_status_filter_by_host on;



location /status {
            vhost_traffic_status_display;
            vhost_traffic_status_display_format html;
        }
nginx -s reload
