linux|如何在docker里部署lnmp linux|docker

简介
docker容器是一个开源的应用容器，具有高移植性，让开发者同意将所有应用以及依赖包打包到容器上，用起来十分方便；lnmp服务，L指linux操作系统,是目前最流行的开源操作系统；N指Nginx，是一个高性能http和反向代理服务器；M指mysql数据库，是一个小型关系型数据库管理系统；P指php，是一种在服务器上执行的嵌入型HTML文档的脚本语言。

实验步骤：

1.安装docker

[root@localhost ~]# curl -sSL https://get.daocloud.io/docker | sh # Executing docker install script, commit: 7cae5f8b0decc17d6571f9f52eb840fbc13b2737 + sh -c 'yum install -y -q yum-utils' 软件包 yum-utils-1.1.31-54.el7_8.noarch 已安装并且是最新版本 ............ [root@localhost ~]# systemctl restart docker

2.拉取mysql镜像并查看，创建本地存储映射文件目录

[root@localhost ~]# docker pull mysql:5.7 5.7: Pulling from library/mysql 69692152171a: Pull complete 1651b0be3df3: Pull complete 951da7386bc8: Pull complete ............ [root@localhost ~]# docker images | grep mysql mysql5.72c9028880e584 days ago447MB [root@localhost ~]# mkdir -p /opt/mysql/conf /opt/mysql/logs /opt/mysql/data

2.1.测试mysql是否能运行，注意第二个命令那password是设置自己的密码，我设为0000，大家自行设置，如下图则数据库安装成功

[root@localhost ~]# cd /opt/mysql [root@localhost mysql]# docker run -p3306:3306 --name mysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=0000 -d mysql:5.7 17557f7031f3e533ab824861f5971150c39e415e9986cd6e804ddca56b4b2811 [root@localhost mysql]# docker ps CONTAINER IDIMAGECOMMANDCREATEDSTATUSPORTSNAMES 17557f7031f3mysql:5.7"docker-entrypoint.s…"22 seconds agoUp 20 seconds0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcpmysql [root@localhost mysql]# docker exec -it mysql bash root@17557f7031f3:/# mysql -p0000 mysql: [Warning] Using a password on the command line interface can be insecure.

3.拉取php镜像

[root@localhost ~]# mkdir -p /opt/www/html [root@localhost ~]# docker pull php:7.0-fpm 7.0-fpm: Pulling from library/php 177e7ef0df69: Pull complete 9bf89f2eda24: Pull complete 350207dcf1b7: Pull complete [root@localhost ~]# cd /opt/www/html [root@localhost html]# cat index.php [root@localhost html]# docker run -d -p 9000:9000 --name rc-phpfpm --restart=always -v $PWD/html:/var/www/html --link mysql:mysql php:7.0-fpm 7cf5f1e28fceec9cc09a330827bc30c6cd83482f0d63cecaebda9f85cacf34cf [root@localhost html]# docker exec -ti rc-phpfpm /bin/bash root@7cf5f1e28fce:/var/www/html# docker-php-ext-install pdo_mysql Configuring for: PHP Api Version:20151012 Zend Module Api No:20151012 Zend Extension Api No:320151012 checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E

4.拉取nginx镜像

[root@localhost html]# cd [root@localhost ~]# docker pull nginx Using default tag: latest latest: Pulling from library/nginx 69692152171a: Already exists 49f7d34d62c1: Pull complete [root@localhost ~]# cd /opt/www [root@localhost www]# docker run -d -p 80:80 --name rc-nginx -v $PWD/html:/var/www/html --link rc-phpfpm:rc-phpfpm nginx 945625a91830465b74048cca874e112392293c94d4601030fc5fac8a67e31a11 [root@localhost ~]# cat /etc/nginx.conf server {listen 80; server_name localhost; charset utf-8; localtion ~ \.php$ {root /var/www/html; fastcgi_index index.php; fastcgi_pass rc-phpfpm:9000 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }

【linux|如何在docker里部署lnmp】5.大功告成。现在测试一下所有服务是否部署完成

[root@localhost ~]# docker restart rc-nginx rc-nginx [root@localhost ~]# docker restart rc-phpfpm rc-phpfpm [root@localhost ~]# docker exec -it mysql bash root@17557f7031f3:/# mysql -p0000 mysql: [Warning] Using a password on the command line interface can be insecure.

总结：docker中部署lnmp还是比较简单的，主要就是在docker中拉取三个镜像就好了！
