2. Write the Dockerfile script of Nginx
[root@docker-lnmp nginx]# vim Dockerfile FROM centos:7 MAINTAINER this is nginx image RUN yum -y install pcre-devel zlib-devel gcc gcc-c++ make;useradd -M -s /sbin/nologin nginx ADD nginx-1.12.0.tar.gz /usr/local/src/ WORKDIR /usr/local/src/nginx-1.12.0 RUN ./configure \ --prefix=/usr/local/nginx \ --user=nginx \ --group=nginx \ --with-http_stub_status_module;make -j 4 && make install ENV PATH /usr/local/nginx/sbin:$PATH ADD nginx.conf /usr/local/nginx/conf/ ADD wordpress-4.9.4-zh_CN.tar.gz /usr/local/nginx/html RUN chmod 777 -R /usr/local/nginx/html/ EXPOSE 80 VOLUME [ "/usr/local/nginx/html/" ] CMD [ "/usr/local/nginx/sbin/nginx","-g","daemon off;" ]
3. Configure nginx.conf file
[root@docker-lnmp nginx]# vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;

}
}
}4. Generate nginx image
[root@docker-lnmp nginx]# docker build -t lnmp:nginx1 . [root@docker-lnmp nginx]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE lnmp nginx1 3cb059547907 13 seconds ago 523MB centos 7 eeb6ee3f44bd 2 months ago 204MB
5. Customize the ip address and start the image container (limit the maximum use of 500MB of memory and 1G of Swap by the Nginx container)
[root@docker-lnmp nginx]# docker run -d --name nginx -p 80:80 -m 500m --memory-swap 1g --net mynetwork --ip 172.18.0.11 lnmp:nginx1
a1c5bb69bd325c14f49a3f242745d0e68b6372bf7c31fda47ca5523045a6aac6
[root@docker-lnmp nginx]# docker ps -a

a1c5bb69bd32 lnmp:nginx1 "/usr/local/nginx/sb..." 20 seconds ago Up 19 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp nginx
[root@docker-lnmp nginx]# docker inspect nginx
......
"IPAddress": "172.18.0.11",
......6. Verify Nginx
[root@docker-lnmp nginx]# curl http://192.168.32.15:80

</html>7. Backup Nginx mirror to local
[root@docker-lnmp ~]# cd /opt/ [root@docker-lnmp opt]# mkdir lamp_images_bak-2021.12.1 [root@docker-lnmp opt]# cd lamp_images_bak-2021.12.1/ [root@docker-lnmp lamp_images_bak-2021.12.1]# docker save -o nginx_image-2021.12.1 lnmp:nginx1
5, Install MySQL
1. Create MySQL directory
[root@docker-lnmp ~]# cd /opt/ [root@docker-lnmp opt]# mkdir mysql [root@docker-lnmp opt]# cd mysql/ [root@docker-lnmp mysql]# ls mysql-boost-5.7.20.tar.gz
2. Configure my.cnf file
