1、环境准备
docker 版本
[root@iZ2ze8dv3a3mevar9w80f1Z software]# docker version
Client:
Version: 1.13.1
API version: 1.26
Package version: docker-1.13.1-103.git7f2769b.el7.centos.x86_64
Go version: go1.10.3
Git commit: 7f2769b/1.13.1
Built: Sun Sep 15 14:06:47 2019
OS/Arch: linux/amd64
Server:
Version: 1.13.1
API version: 1.26 (minimum version 1.12)
Package version: docker-1.13.1-103.git7f2769b.el7.centos.x86_64
Go version: go1.10.3
Git commit: 7f2769b/1.13.1
Built: Sun Sep 15 14:06:47 2019
OS/Arch: linux/amd64
Experimental: false
linux 内核
linux 内核2.6及以上版本:
只有2.6之后才支持epool ,在此之前使用select或pool多路复用的IO模型,无法解决高并发压力的问题。通过命令uname -a 即可查看。
[root@iZ2ze8dv3a3mevar9w80f1Z software]# uname -a
Linux iZ2ze8dv3a3mevar9w80f1Z 3.10.0-1062.1.2.el7.x86_64 #1 SMP Mon Sep 30 14:19:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
2、安装Nginx镜像
docker pull nginx
安装后,执行 docker images 查看 nginx 镜像。
3、创建nginx 对应的目录为了启动容器的时候做映射
mkdir -p /data/nginx/{conf,conf.d,html,logs}
4、创建配置文件
在/data/ngxin/conf 下创建配置文件nginx.conf
user nginx;
worker_processes 1;
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;
}
在/data/nginx/conf.d 目录下创建default.conf
server {
listen 80;
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;
#}
}
5、创建Nginx容器
docker run --name nginx8080 -d -p 8080:80 -v /data/nginx/html:/usr/share/nginx/html -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/logs:/var/log/nginx -v /data/nginx/conf.d:/etc/nginx/conf.d -d nginx
6、创建index.html
<html>
<title>Mynginx</title>
</head>
<body>
<h1>
hello world!
</h1>
</body>
</html>
