## 2。 k8s部署测试(单机，非集群模式！) ##

1个实例，不限制CPU，采用ingress方式暴露服务

nginx-ingress-test.yml配置

## 3. 裸机部署 ##

确认docker内nginx版本

/ # /usr/sbin/nginx -V
    nginx version: nginx/1.19.3
    built by gcc 9.3.0 (Alpine 9.3.0) 
    built with OpenSSL 1.1.1g  21 Apr 2020
    TLS SNI support enabled
    configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --with-perl_modules_path=/usr/lib/perl5/vendor_perl --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --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-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-Os -fomit-frame-pointer' --with-ld-opt=-Wl,--as-needed

采用相同版本nginx，相同编译参数，编译安装（本地gcc为：9.2.1）

[yeqiang@harbor Downloads]$ cd nginx-1.19.3/
    [yeqiang@harbor nginx-1.19.3]$ ./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --with-perl_modules_path=/usr/lib/perl5/vendor_perl --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --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-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-Os -fomit-frame-pointer' --with-ld-opt=-Wl,--as-needed
    [yeqiang@harbor nginx-1.19.3]$ make -j12
    [yeqiang@harbor nginx-1.19.3]$ sudo make install

直接复制容器中的nginx配置文件

[yeqiang@harbor nginx-1.19.3]$ sudo su
    [root@harbor nginx-1.19.3]# cd /etc/nginx/
    [root@harbor nginx]# cp nginx.conf nginx.conf.bak
    [root@harbor nginx]# docker cp 5e639b847735:/etc/nginx/nginx.conf .
    [root@harbor nginx]# docker cp 5e639b847735:/etc/nginx/conf.d .

其中启动用户改为nobody

user  nobody;
    worker_processes  auto;
    
    error_log  /var/log/nginx/error.log warn;
    pid        /var/run/nginx.pid;
    
    
    events {
        worker_connections  1024;
    }
    
    
    http {
        include       /etc/nginx/mime.types;
        default_type  application/octet-stream;
    
        log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                          '$status $body_bytes_sent "$http_referer" '
                          '"$http_user_agent" "$http_x_forwarded_for"';
    
        access_log  /var/log/nginx/access.log  main;
    
        sendfile        on;
        #tcp_nopush     on;
    
        keepalive_timeout  65;
    
        #gzip  on;
    
        include /etc/nginx/conf.d/*.conf;
    }

conf.d/default.conf启动端口改为81（本地端口被ingress服务占用了）

server {
        listen       81;
        listen  [::]:81;
        server_name  localhost;
    
        #charset koi8-r;
        #access_log  /var/log/nginx/host.access.log  main;
    
        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        }
    
        #error_page  404              /404.html;
    
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}
    
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}
    
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

创建目录

[root@harbor nginx]# mkdir -p /var/cache/nginx/client_temp -p
    [root@harbor nginx]# chown root:nobody /var/cache/nginx/ -R

复制容器中的html目录（做到index.html体积一样大）

[root@harbor ~]# docker cp 4370fb6acb18:/usr/share/nginx/html /usr/share/nginx/
    [root@harbor nginx]$ sudo chown nobody:root /usr/share/nginx/ -R

Docker部署服务方式性能损耗排行：

1. 网络：服务提供docker-proxy

2. 文件系统IO及终端日志（本次测试打开日志情况下，终端会打印日志）

k8s部署服务方式性能损耗排行：

1. 网络:服务提供ingress-controller

2. dockerd
