一、tomcat（更换jdk）

mkdir tomcat
cd tomcat/
tar xf jdk-8u191-linux-x64.tar.gz
tar xf apache-tomcat-8.5.40.tar.gz

vim Dockerfile 
FROM centos:7
MAINTAINER Crushlinux <syh@163.com> ADD jdk1.8.0_191 /usr/local/java
ENV JAVA_HOME /usr/local/java
ENV JAVA_BIN /usr/local/java/bin
ENV JRE_HOME /usr/local/java/jre
ENV PATH $PATH:/usr/local/java/bin:/usr/local/java/jre/bin
ENV CLASSPATH /usr/local/java/jre/bin:/usr/local/java/lib:/usr/local/java/jre/lib/charsets.jarADD apache-tomcat-8.5.40 /usr/local/tomcat
RUN chmod 755 /usr/local/tomcat/bin/startup.sh
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtimeEXPOSE 8080CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]

docker build -t tomcat:new .
docker images tomcat:new
docker run -d -p 8080:8080 --name tomcat-test --restart=always tomcat:new

二、mysql

mkdir mysql
cd mysql/vim Dockerfile 
FROM centos:7
MAINTAINER Crushlinux <syh@163.com>#安装mariadb数据库
RUN yum install -y mariadb mariadb-server mariadb-devel #设置环境变量，便于管理
ENV MARIADB_USER root
ENV MARIADB_PASS 123456#让容器支持中文
ENV LC_ALL en_US.UTF-8#初始化数据库
ADD db_init.sh /root/db_init.sh
RUN chmod 775 /root/db_init.sh && /root/db_init.sh#导出端口
EXPOSE 3306#设置默认启动命令
CMD ["mysqld_safe"]

 

vim db_init.sh   主要用于授权
#!/bin/bash
mysql_install_db --user=mysql
sleep 3
mysqld_safe &
sleep 3
mysql -e "use mysql; grant all privileges on *.* to '$MARIADB_USER'@'%' identified by '$MARIADB_PASS' with grant option;"
h=$(hostname)
mysql -e "use mysql; update user set password=password('$MARIADB_PASS') where user='$MARIADB_USER' and host='$h';"
mysql -e "flush privileges;"

docker build -t mysql:new .
docker run -d -p 3306:3306 --name mysql-test --restart=always mysql:new 

yum -y install mariadb mariadb-devel
mysql -h 192.168.77.123 -u root -P 3306 -p123456

 三、lnmp架构

mkdir lnmp
cd lnmp/vim Dockerfile
#基础镜像
FROM centos:7#维护该镜像的用户信息
MAINTAINER Crushlinux <syh@163.com> #配置Nginx 的YUM 源
RUN rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm #安装nginx
RUN yum -y install nginx#安装mysql 和php
RUN rpm --rebuilddb && yum -y install mariadb-devel mariadb-server mariadb php php-fpm#修改nginx 配置文件，使之支持PHP
ADD default.conf /etc/nginx/conf.d/default.conf#修改php-fpm 配置文件允许nginx 访问
RUN sed -i '/^user/s/apache/nginx/g' /etc/php-fpm.d/www.conf
RUN sed -i '/^group/s/apache/nginx/g' /etc/php-fpm.d/www.conf#设置环境变量，便于管理
ENV MARIADB_USER root
ENV MARIADB_PASS 123456#mysql 数据库授权
ADD db_init.sh /root/db_init.sh
RUN chmod 775 /root/db_init.sh
RUN /root/db_init.sh#添加测试页面
ADD index.php /usr/share/nginx/html/index.php#定义时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime#分别开启80 端口，443 端口，9000 端口，3360 端口
EXPOSE 80
EXPOSE 9000
EXPOSE 3306#复制脚本，设置权限，启动容器时启动该脚本
ADD run.sh /run.sh
RUN chmod 775 /run.sh
CMD ["/run.sh"]

vim db_init.sh  主要用于授权
#!/bin/bash
/usr/bin/mysql_install_db --user=mysql
sleep 3
/usr/bin/mysqld_safe &
sleep 3
mysql -e "use mysql; grant all privileges on *.* to '$MARIADB_USER'@'%' identified by '$MARIADB_PASS' with grant option;"
h=$(hostname)
mysql -e "use mysql; update user set password=password('$MARIADB_PASS') where user='$MARIADB_USER' and host='$h';"
mysql -e "flush privileges;"

vim index.php
<?php
phpinfo();
?>

                                           

vim default.conf  修改nginx配置文件
server {listen       80;server_name  localhost;location / {root   /usr/share/nginx/html;index  index.html index.php index.htm;}location ~ \.php$ {root           /usr/share/nginx/html;fastcgi_pass   127.0.0.1:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html$fastcgi_script_name;include        fastcgi_params;}
}

vim run.sh                  启动nginx脚本
#!/bin/bash
/usr/sbin/nginx && /usr/sbin/php-fpm && /usr/bin/mysqld_safe

 

docker build -t lnmp:new .
docker images lnmp
docker run -d -p 80:80 -p 3306:3306 -p 9000:9000 --name lnmp-test --restart=always lnmp:new 

 四、redis

mkdir redis
cd redis/vim Dockerfile 
FROM centos:7
MAINTAINER Crushlinux <syh@163.com>RUN yum -y update && yum -y install epel-release && yum -y install redis
RUN sed -i -e 's@bind 127.0.0.1@bind 0.0.0.0@g' /etc/redis.conf
RUN sed -i -e 's@protected-mode yes@protected-mode no@g' /etc/redis.conf
RUN echo "requirepass 123456" >> /etc/redis.confRUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
EXPOSE 6379CMD [ "/usr/bin/redis-server","/etc/redis.conf"]

docker build -t redis:new .
docker images redis:new 
docker run -d -p 6379:6379 --name redis-test --restart=always redis:new

rpm -ivh /root/epel-release-latest-7.noarch.rpm
yum -y install redis
redis-cli -h localhost -a 123456

 

以上就是dockerfile构建tomcat、mysql、lnmp、redis镜像的操作

如有错误欢迎各位大佬批评指正，我们共同进步
