Docker搭建LNMP

本操作在VMware中完成。

优化Linux系统

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config &> /dev/null
setenforce 0
systemctl stop firewalld &> /dev/null
systemctl disable firewalld &> /dev/null
iptables -F
systemctl stop NetworkManager &> /dev/null
systemctl disable NetworkManager &> /dev/null
echo 1 > /proc/sys/net/ipv4/ip_forward
hostnamectl set-hostname docker-server
exit

配置yum源

[root@docker-server ~]# vim /etc/yum.repos.d/CentOS7.repo
​
[aliyun-os]
name=aliyun-os
baseurl=https://mirrors.aliyun.com/centos/7/os/x86_64/
enabled=1
gpgcheck=0
​
[aliyun-epel]
name=aliyun-epel
baseurl=https://mirrors.aliyun.com/epel/7/x86_64/
enabled=1
gpgcheck=0
​
[aliyun-extra]
name=aliyun-extra
baseurl=https://mirrors.aliyun.com/centos/7/extras/x86_64/
enabled=1
gpgcheck=0
​
[root@docker-server ~]# yum clean all && yum makecache
[root@docker-server ~]# yum install -y yum-utils
[root@docker-server ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@docker-server ~]# yum clean all && yum makecache

配置pip

[root@docker-server ~]# mkdir ~/.pip
[root@docker-server ~]# vim ~/.pip/pip.conf
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com

安装docker

[root@docker-server ~]# yum remove -y docker docker-io docker-selinux python-docer-py
[root@docker-server ~]# yum install -y docker-ce
[root@docker-server ~]# systemctl start docker
[root@docker-server ~]# systemctl enable docker
[root@docker-server ~]# systemctl status docker
[root@docker-server ~]# docker version

配置国内Docker仓库加速站点

登录阿里云，控制台，搜索容器镜像服务，找到镜像加速器，看对应的操作文档。

[root@docker-server ~]# vim /etc/docker/daemon.json
{
    "registry-mirrors": [......]
}
​
[root@docker-server ~]# systemctl daemon-reload
[root@docker-server ~]# systemctl restart docker && systemctl status docker

测试拉取镜像是否成功

​
启动容器weme_mysql
​
[root@docker-server ~]# docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=weme --name weme_mysql mysql:5.7
3eecbc7e374139c986f7dc7712ef7fe4c9e019952e3897429f262dc3de1b16e8
参数说明
-d 让容器在后台运行
-p 添加主机到容器的端口映射
-e 设置环境变量，这里设置mysql的root用户的初始密码
--name 容器的名称、只要求唯一性

获取php7.2镜像

Status: Downloaded newer image for php:7.2-fpm
docker.io/library/php:7.2-fpm
​
启动PHP容器
​
[root@docker-server ~]# docker run -d -v /var/nginx/www/html:/var/www/html -p 9000:9000 --link weme_mysql:mysql --name weme_phpfpm php:7.2-fpm
5f0ee6a370e096f4852e2030aa3baca7f7090dedefcbea3a9d5e2ba03770c2e5
参数说明
-d 让容器在后台运行
-p 添加主机到容器的端口映射
-v 添加目录映射，主机上的/var/nginx/www/html映射到容器里面 的/var/www/html,如果主机没有这个目录就创建这个目录，或者映射别的目录，但是后面路径要统一
-name 容器的名字
-link 容器与另外一个容器建立联系，这样就可以在当前的容器去使用另一个容器里的服务
​
测试目录映射
在主机/var/nginx/www/html目录下创建PHP测试界面，会直接映射到容器里面。
​
[root@docker-server ~]# vim /var/nginx/www/html/index.php

[root@docker-server ~]# docker exec -it 5f0ee6a370e0 /bin/bash
root@5f0ee6a370e0:/var/www/html# ls
index.php
root@5f0ee6a370e0:/var/www/html# cat index.php

获取Nginx1.12.2镜像

root@5f0ee6a370e0:/var/www/html# exit
exit
[root@docker-server ~]# docker pull nginx:1.12.2
1.12.2: Pulling from library/nginx
f2aa67a397c4: Pull complete 
e3eaf3d87fe0: Pull complete

Digest: sha256:72daaf46f11cc753c4eab981cbf869919bd1fee3d2170a2adeac12400f494728
Status: Downloaded newer image for nginx:1.12.2
docker.io/library/nginx:1.12.2
​
启动Nginx容器
​
[root@docker-server ~]# docker run -d -p 80:80 --name weme_nginx -v /var/nginx/www/html:/var/www/html --link weme_phpfpm:phpfpm --name weme_nginx nginx:1.12.2
6e0f65dd757366a4709f16ceb75fcf4025b158a641a6cec8c271d5c7e8959a7b
参数说明
-d 让容器运行在后台
-p 添加主机到容器的端口映射
-v 添加目录映射，这里最好nginx容器的根目录最好写成和php容器中根目录一样。但是不一定非要一样,如果不一样在配置nginx的时候需要注意
-name 容器的名称
-link 容器之间建立起来联系
​

修改Nginx的配置文件，让其支持php，方式有多种，这里我用直接拷贝出配置文件修改再导入进去即可。

[root@docker-server ~]# cd /opt/
[root@docker-server opt]# docker cp 6e0f65dd7573:/etc/nginx/conf.d/default.conf /opt/
[root@docker-server opt]# ls
containerd  default.conf
[root@docker-server opt]# cat 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$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
​
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
​
[root@docker-server opt]# vim default.conf
server {
    listen       80;
    server_name  localhost;
    location / {
        root   /var/www/html;                       # 修改这里默认的路径
        index  index.html index.htm index.php;     #这里加入添加php的方式
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
    location ~ \.php$ {
        root           html;
        fastcgi_pass   5f0ee6a370e0:9000;        #这里可以用容器ID，也可以用容器IP，都具备唯一性，注意这里的9000端口是容器的端口，不是宿主机的端口
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /var/www/html/$fastcgi_script_name;      #修改这里的路径
        include        fastcgi_params;
    }
}

修改完毕后复制配置文件到Nginx容器里面

[root@docker-server opt]# docker cp default.conf 6e0f65dd7573:/etc/nginx/conf.d/default.conf
​
进入容器里面重新加载配置文件
​
[root@docker-server opt]# docker exec -it 6e0f65dd7573 /bin/bash
root@6e0f65dd7573:/# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
root@6e0f65dd7573:/# nginx -s reload
2022/11/14 07:58:26 [notice] 22#22: signal process started
​
root@6e0f65dd7573:/# exit
exit
参数说明
-t 在容器里面生产一个伪终端
-i 对容器内的标准输入（STDIN）进行交互

查看所有容器映射的端口
