3. 制作镜像
* 构建php dockerfile
#Php-fpm #Version 1.0.1 #Author lisea #Base Image FROM centos:7 #Maintainer MAINTAINER lisea [email protected] #Commands RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm RUN yum install php-fpm -y RUN sed -i -e ‘s\listen = 127.0.0.1:9000\listen = 0.0.0.0:9000\g‘ -e ‘s\listen.allo wed_clients = 127.0.0.1\;listen.allowed_clients = 127.0.0.1\g‘ /etc/php-fpm.d/www.c onf RUN sed -i ‘s\;daemonize = yes\daemonize = no\g‘ /etc/php-fpm.conf EXPOSE 9000 CMD ["php-fpm"]
* 构建 php 镜像
[[email protected] php-fpm]# docker build -t lisea/php-fpm:v1.0.1 .
* 准备nginx配置nginx.conf文件

#If you have a lot of static files to serve through Nginx then caching of the files‘ metadata (not the actual files‘ contents) can save some latency.

open_file_cache_valid 30s;
open_file_cache_min_uses 1;
open_file_cache_errors on;
########################## vhost #############################
include conf.d/*.conf;
}
* 准备nginx配置php服务相关 nginx_localhost_80.conf 文件
php:9000是通过后面的--link 容器之间互联指定
server {
listen 80;
server_name localhost;
root /data/www;
index index.html index.htm index.php;
location ~ [^/]\.php(/|$) {
fastcgi_pass php:9000;
#fastcgi_pass unix:/usr/local/php-fastcgi/php-fpm.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ {
expires 30d;
access_log off;
}
location ~ .*\.(js|css)?$ {
expires 7d;
access_log off;
}
location ~ /\.ht {
deny all;
}
}
* 构建 nginx dockerfile 文件
#Nginx #Version 1.0.1 #Author lisea #Base Image FROM centos:7 #Maintainer MAINTAINER lisea [email protected] #Commands RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm RUN yum install nginx -y ADD nginx.conf /etc/nginx/nginx.conf ADD nginx_localhost_80.conf /etc/nginx/conf.d/localhost_80.conf EXPOSE 80 CMD ["nginx"]
* 构建 nginx 镜像
[[email protected] nginx]# docker build -t lisea/nginx:v1.0.1 .
* 准备mariadb 启动脚本 startup.sh
#!/bin/bash
if [ ! -f /var/lib/mysql/ibdata1 ]; then
mysql_install_db
chown mysql.mysql -R /var/lib/mysql
/usr/bin/mysqld_safe &
sleep 10s
mysql -e "grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘123456‘; FLUSH PRIVILEGES;"
kill -s TERM `ps aux | grep mysqld | grep -v ‘grep‘ | awk ‘{print $2}‘`
sleep 10s
fi
/usr/bin/mysqld_safe
* 构建mariadb(mysql) dockerfile
#Mariadb #Version 1.0.1 #Author lisea #Base Image FROM centos:7 #Maintainer MAINTAINER lisea [email protected] #Commands RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm RUN yum install mariadb-server mariadb -y ADD startup.sh /opt/startup.sh RUN chmod +x /opt/startup.sh EXPOSE 3306 CMD ["/bin/bash","/opt/startup.sh"]
* 构建 mysql 镜像
[[email protected] mysql]# docker build -t lisea/mariadb:v1.0.1 .
* 查看所有镜像
[[email protected] lnmp]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE lisea/mariadb v1.0.1 5925448a6fb6 3 minutes ago 493.6 MB lisea/nginx v1.0.1 f1aba93ce33d 52 minutes ago 391.4 MB lisea/php-fpm v1.0.1 d205ea9fcdba About an hour ago 350.1 MB docker.io/centos 7 3bee3060bfc8 2 weeks ago 192.5 MB
4. 编写docker-compose
* docker-compose.yml
version: "2" services: lnmp_nginx: image: lisea/nginx:v1.0.1 ports: - "8080:80" links: - "lnmp_php:php" volumes: - /data/www:/data/www lnmp_php: image: lisea/php-fpm:v1.0.1 volumes: - /data/www:/data/www lnmp_mariadb: image: lisea/mariadb:v1.0.1 ports: - "3306:3306" volumes: - /data/mariadb:/var/lib/mysql
* 开始构建并运行 -d 指定后台运行
[[email protected] lnmp]# docker-compose up -d Creating network "lnmp_default" with the default driver Creating lnmp_lnmp_php_1 ... Creating lnmp_lnmp_mysql_1 ... Creating lnmp_lnmp_php_1 Creating lnmp_lnmp_php_1 ... done Creating lnmp_lnmp_mariadb_1 ... done Creating lnmp_lnmp_nginx_1 ... done
* 查看端口监听状态
[[email protected] lnmp]# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 975/sshd tcp6 0 0 :::3306 :::* LISTEN 15138/docker-proxy- tcp6 0 0 :::8080 :::* LISTEN 15320/docker-proxy- tcp6 0 0 :::22 :::* LISTEN 975/sshd
5. 测试lnmp环境
* 路径切换到nginx web目录 [/data/www]
[[email protected] lnmp]# cd /data/www/
* index.php
<?php phpinfo(); ?>
* 浏览器访问 ip:8080/index.php
6. 总结
以需求驱动技术，技术本身没有优略之分，只有业务之分。
