第四章 LINUX Docker LNMP项目搭建
一、项目环境
公司在实际的生产环境中，需要使用Docker 技术在一台主机上创建LNMP服务并运行Wordpress网站平台。然后对此服务进行相关的性能调优和管理工作
1.环境描述
| 容器宿主机 | 操作系统 | ip地址 | 主要软件 |
|---|---|---|---|
| Docker | CentOS 7.3 x86_64 | 192.168.58.60 | Docker 19.03 |
2.容器ip地址规划
宿主机 ip地址：192.168.58.60
nginx容器 ip地址：172.18.0.10
mysql容器 ip地址：172.18.0.20
php容器 ip地址：172.18.0.30
3.任务需求
1）使用Docker构建LNMP环境并运行Wordpress网站平台
2）限制Nginx容器最多使用500Mb的内存和1G的Swap
3）限制Mysql容器写 /dev/sda 的速率为 10 MB/s
4）将所有容器进行快照，然后将Docker镜像打包成tar包备份到本地
二、部署过程
###前提本地已经安装docker，配置lnmp的文件目录
cd /opt/
mkdir mylnmp
cd /opt/mylnmp/
mkdir nginx mysql php
###部署一个有所有软件依赖包的镜像，以便进行分阶段构建镜像
cd /opt/
vim Dockerfile
FROM centos:7 ###从公有仓库pull一个centos:7的镜像
COPY qinghua-yum.sh /opt/ ###上传修改yum源的脚本
RUN chmod +x /opt/qinghua-yum.sh && /opt/qinghua-yum.sh && \
yum -y install pcre-devel zlib-devel openssl-devel \
gcc gcc-c++ make ncurses ncurses-devel bison cmake gd \
libjpeg-devel \
libpng-devel \
freetype-devel \
libxml2-devel \
zlib-devel \
curl-devel \
openssl-devel
docker build -t centos7:mylnmp
docker images
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mylnmp
docker network ls
1.部署构建 nginx 镜像
###nginx目录下已上传nginx安装包、论坛安装包、nginx配置文件
cd /opt/mylnmp/nginx/
ls
###部署 nginx 的 Dockerfile
cd /opt/mylnmp/nginx/
vim Dockerfile
FROM centos7:mylnmp
ADD nginx-1.24.0.tar.gz /usr/local/
RUN useradd -M -s /sbin/nologin nginx && \
cd /usr/local/nginx-1.24.0 && \
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
COPY nginx.conf /usr/local/nginx/conf/nginx.conf
FROM centos:7
COPY --from=0 /usr/local/nginx/ /usr/local/nginx/
RUN useradd -M -s /sbin/nologin nginx
EXPOSE 80
#EXPOSE 443
CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]
docker build -t nginx:lnmp
docker images
docker run -d --name nginx --network=myLnmp --ip=172.18.0.10 -p 80:80 -v /opt/mylnmp/nginx/html/:/usr/local/nginx/html/ -m 500m - -memory-swap=1.5g centos7:myLnmp
docker ps -a
2.部署构建 mysql 镜像
###mysql目录下已上传mysql安装包、mysql配置文件
