Docker-构建镜像并实现LNMP架构

一、搭建LNMP

基础配置

1、制作Nginx镜像

制作dockerfile

bash 复制代码

vim dockerfile

FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
RUN curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
RUN yum clean all
RUN yum makecache
RUN yum -y install zlib-devel pcre-devel gcc make openssl-devel
ADD nginx-1.19.5.tar.gz /opt
WORKDIR /opt/nginx-1.19.5
RUN ./configure --prefix=/usr/local/nginx && make && make install
ADD nginx.conf /usr/local/nginx/conf/nginx.conf
EXPOSE 80
EXPOSE 443
ADD run.sh /run.sh
RUN chmod +x /run.sh
CMD ["/run.sh"]

编辑nginx配置文件

bash 复制代码

vim nginx.conf

        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;

        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi.conf;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration

}
daemon off;

编辑容器前台运行脚本

bash 复制代码

vim run.sh

bash 复制代码

#!/bin/bash
/usr/local/nginx/sbin/nginx

创建镜像

bash 复制代码

docker build -t mynginx .

查看

bash 复制代码

docker images

2、制作PHP镜像

制作dockerfile

bash 复制代码

vim dockerfile

FROM centos:7
MAINTAINER jacker
RUN rm -rf /etc/yum.repos.d/*
RUN curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
RUN curl -o /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
RUN yum cleanall
RUN yum makecache
RUN yum install -y wget net-tools php php-fpm php-common php-devel php-mysql
RUN sed -i 's/127.0.0.1/0.0.0.0/g' /etc/php-fpm.d/www.conf
RUN sed -i 's/listen.allowed_clients/;listen.allowed_clients/g' /etc/php-fpm.d/www.conf
RUN sed -i 's/;default_charset/default_charset/g' /etc/php.ini
EXPOSE 9000
CMD ["php-fpm"]

创建PHP镜像

bash 复制代码

docker build -t myphp .

3、制作MySQL镜像

制作dockerfile

bash 复制代码

vim dockerfile

FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
RUN curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
RUN yum clean all
RUN yum makecache
RUN yum -y install mariadb mariadb-server
RUN chown -R mysql:mysql /var/lib/mysql
ADD run.sh /run.sh
RUN chmod +x /run.sh
RUN /run.sh
EXPOSE 3306
CMD ["mysql_safe"]

编辑mysql配置文件

bash 复制代码

vim my.cnf

bash 复制代码

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

编辑容器前台运行脚本

bash 复制代码

vim run.sh

bash 复制代码

#!/bin/bash
mysql_install_db --user=mysql
sleep=3
mysqld_safe &
sleep=3
mysqladmin -u "root" password "123456"
mysql -uroot -p123456 -e "grant all privileges on *.* to 'root'@'%' identified by '123456';"
mysql -uroot -p123456 -e "grant all privileges on *.* to 'root'@'localhost' identified by '123456';"
mysql -uroot -p123456 -e "flush privileges;"

创建mysql镜像

bash 复制代码

docker build -t my_mysql .

4、启动容器

myphp

bash 复制代码

docker run -id --net=my_net -v /web:/web --name php01 myphp

mynginx

bash 复制代码

docker run -id --net=my_net -v /web:/web -v /opt/nginx/nginx.conf:/usr/local/nginx/conf/nginx.conf -p 80:80 --name nginx01 mynginx

my_mysql

bash 复制代码

docker run -p 3306:3306 --name mysql01 -v /opt/mysql/my.cnf:/etc/my.cnf --net=my_net -d my_mysql

查看

bash 复制代码

docker ps -a

5、测试一：

bash 复制代码

cd /web

vim aaa.php
###编辑内容###
<?php
phpinfo();
?>

vim bbb.php
###编辑内容###
<?php
$link=mysqli_connect('mysql01','root','123456');
if($link) echo "test OK";
mysqli_close($link);
?>

6、测试二：

bash 复制代码

cd /web
rm -rf ./*
cp -r wordpress/* /web/
chmod -R 777 /web/
docker exec -it mysql01 /bin/bash
mysql -uroot -p123456
create database wordpress;

docker ps -a

7、制作tomcat镜像

制作dockerfile文件

bash 复制代码

vim dockerfile

FROM centos:7
ADD apache-tomcat-8.5.16.tar.gz /usr/local/
ADD jdk-8u91-linux-x64.tar.gz /usr/local/
RUN mv /usr/local/apache-tomcat-8.5.16 /usr/local/tomcat
RUN mv /usr/local/jdk1.8.0_91 /usr/local/java

ENV JAVA_HOME /usr/local/java
ENV JAVA_BIN /usr/local/java/bin
ENV JRE_HOME /usr/local/java/jre
ENV PARH $PATH:/usr/local/java/bin:/usr/local/java/jre/bin
ENV CLASSPATH $CLASSPATH:/usr/local/java/lib:/usrr/local/java/jre/lib

ADD run.sh /run.sh
RUN chmod +x /run.sh
CMD ["/run.sh"]

修改内核参数

bash 复制代码

echo "vm.max_map_count=655360" >> /etc/sysctl.conf
sysctl -p

编辑容器前台运行脚本

bash 复制代码

vim run.sh

bash 复制代码

#!/bin/bash
export JAVA_OPTS ="-Xms2048m -Xmx4096m"
ulimit -n 655360
/usr/local/tomcat/bin/startup.sh
tailf /usr/local/tomcat/logs/catalina.out

创建镜像

bash 复制代码

docker build -t mytomcat .

创建容器

bash 复制代码

docker run -itd -p 12345:8080 --name tomcat01 mytomcat
