nginx-manager 安装配置

编译部分为：

默认的openssl

./auto/configure --prefix=/home/hwMindX --conf-path=/home/hwMindX/conf/nginx.conf --error-log-path=/home/hwMindX/log/error.log --http-log-path=/home/hwMindX/log/access.log --pid-path=/home/hwMindX/log/nginx.pid --lock-path=/home/hwMindX/log/nginx.lock --with-http_ssl_module --http-client-body-temp-path=/tmp/client_body_temp --http-proxy-temp-path=/tmp/proxy_temp --http-fastcgi-temp-path=/tmp/fastcgi_temp --http-uwsgi-temp-path=/tmp/uwsgi_temp --http-scgi-temp-path=/tmp/scgi_temp

指定openssl

 cd ./opensource/pcre2/
 autoreconf -ivf
./configure

 cd ./opensource/nginx/"
chmod 750 auto/configure

./auto/configure --prefix=/home/hwMindX --with-openssl=./opensource/openssl/ --with-pcre=./opensource/pcre2/ --conf-path=/home/hwMindX/conf/nginx.conf --error-log-path=/home/hwMindX/logs/error.log --http-log-path=/home/hwMindX/logs/access.log --pid-path=/home/hwMindX/logs/nginx.pid --lock-path=/home/hwMindX/logs/nginx.lock --with-http_ssl_module --http-client-body-temp-path=/tmp/client_body_temp --http-proxy-temp-path=/tmp/proxy_temp --http-fastcgi-temp-path=/tmp/fastcgi_temp --http-uwsgi-temp-path=/tmp/uwsgi_temp --http-scgi-temp-path=/tmp/scgi_temp

make -j64

./auto/configure --prefix=/home/hwMindX \
     --with-openssl=./opensource/openssl/ \
     --with-pcre=./opensource/pcre2/ \ 
     --conf-path=/home/hwMindX/conf/nginx.conf \

     --pid-path=/home/hwMindX/logs/nginx.pid \
     --lock-path=/home/hwMindX/logs/nginx.lock \
     --with-http_ssl_module \
     --http-client-body-temp-path=/tmp/client_body_temp \
     --http-proxy-temp-path=/tmp/proxy_temp \

尝试解决：

1. docker run -it 5d4c2c37fed3 /bin/bash 不能进
2. systemctl daemon-reload 重启docker
3. 换个环境低版本docker info可以运行
4. 重装docker
5. 发现居然有一个边侧，卸载了就可以了

问题定位

1. 查看运行进程ps -ef|grep edge
2. 查看edgecore再不断拉起

● edgecore.service - edgecore
     Loaded: loaded (/lib/systemd/system/edgecore.service; enabled; vendor preset: enabled)
     Active: activating (start-pre) since Sat 2023-09-23 09:17:07 UTC; 1ms ago
Cntrl PID: 2563854 (prepare.sh)
      Tasks: 1 (limit: 76529)

3. cat /usr/local/mindx/MEFEdge/software/edge_core/script/prepare.sh

function ensure_pause_image()
{
  if ! docker load < "${PAUSE_TAR_PATH}";then
      echo "warning:load pause.tar.gz failed"
  else
      echo "load pause.tar.gz success"
  fi
  docker image prune -f
}

function main()
{
  log_dir=$1
  log_backup_dir=$2
  edge_core_log_dir="${log_dir}/edge_core"
  edge_core_log_backup_dir="${log_backup_dir}/edge_core"
  edge_core_log="${log_dir}/edge_core/edge_core_run.log"
  create_log_dir "$log_dir" 755
  create_log_dir "$log_backup_dir" 755
  create_log_dir "$edge_core_log_dir" 750
  create_log_dir "$edge_core_log_backup_dir" 750
  create_log "$edge_core_log" 640

  # docker container prune -f
  # docker image prune -f
  ensure_pause_image
}

main "$@"

4. 其中 docker container prune -f 和 docker image prune -f 会强制清除不使用的容器
5. 并且edgecore子进程也在不停的重启
6. 去掉shell中 docker xxx prune -f 就可以了
7. 因为构建docker镜像需要用中间镜像，如果一定被清除，就无法构建

nginx-manager.yaml，apply之后，pod一直pending

1 原因定位：

通过kubectl describe xxx pod -n mindx-edge

报错提示： 0/1 nodes are available: 1 node(s) didn't match node selector

2. 查看yaml 信息为 nodeSelector 配置错误且没有通过 k8s 命令设置

添加lable
kubectl label node hwuser masterselector=dls-master-node
删除lable
kubectl label node hwuser masterselector-
查看label
kubectl get nodes --show-labels

3.注意yaml中各个变量意义，修改的话，一定要注意对应的修改

nginx-manager.yaml，apply之后，pod一直crash

1 原因定位：

通过kubectl logs -f xxx pod -n mindx-edge

定位crash pod 的日志
