提示：文章写完后，目录可以自动生成，如何生成可参考右边的帮助文档
文章目录
一、环境
hostnamectl set-hostname docker-lnmp ##修改主机名
su
cat /etc/resolv.conf ##查看DNS
nameserver 114.114.114.114
ping www.baidu.com
PING www.a.shifen.com (36.152.44.95) 56(84) bytes of data.
64 bytes from 36.152.44.95 (36.152.44.95): icmp_seq=1 ttl=128 time=5.23 ms
64 bytes from 36.152.44.95 (36.152.44.95): icmp_seq=2 ttl=128 time=5.29 ms
^Z
[1]+ 已停止 ping www.baidu.com
setenforce 0 ##关闭核心防护
systemctl stop firewalld ##关闭防火墙
systemctl disable firewalld ##开机关闭防火墙
yum clean all && yum makecache ##重载repo源
二、安装docker
1、安装docker源
yum install -y yum-utils device-mapper-persistent-data lvm2 ##依赖环境
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo ##docker源
2、安装docker
yum install -y docker-ce ##安装社区版
systemctl start docker ##开启docker
systemctl enable docker
systemctl daemon-reload
systemctl restart docker
mkdir docker && cd docker ##创建dockerfile 目录
三、部署docker-lnmp
1、创建nginx-php 、mysql目录
mkdir nignx mysql
2、创建nginx-dockfile、php
cd nginx
上传nginx-1.12.2.tar.gz、wordpress-4.9.4-zh_CN.tar、libmcrypt-2.5.7.tar.gz、nginx.conf、wp-config.php
tar zxvf wordpress-4.9.4-zh_CN.tar.gz
tar zxvf nginx-1.12.2.tar.gz
tar zxvf libmcrypt-2.5.7.tar.gz
tar zxvf php-5.5.38.tar.gz
vim Dockerfile
FROM docker.io/centos:7
RUN yum -y update
RUN yum -y install gcc gcc-c++ openssl-devel openssl autoconf cmake autoconf zlib zlib-devel libtool pcre pcre-devel wget net-tools make

RUN cp /usr/local/php5.5/etc/php-fpm.conf.default /usr/local/php5.5/etc/php-fpm.conf
RUN sed -i 's*;pid = run/php-fpm.pid*pid = run/php-fpm.pid*g' /usr/local/php5.5/etc/php-fpm.conf
RUN sed -i 's/user = nobody/user = nginx/g' /usr/local/php5.5/etc/php-fpm.conf

RUN sed -i 's/pm.max_spare_servers = 3/pm.max_spare_servers = 30/g' /usr/local/php5.5/etc/php-fpm.conf
EXPOSE 9000
EXPOSE 80
3、构建nginx-php镜像和开启服务
docker build -t "centos:nginx-php" .
在这里插入代码片
docker ps -a
docker exec -it 95e2167b5a54 /bin/bash ##进入容器
/etc/init.d/php-fpm start && nginx ##开启服务
exit 退出
4、创建mysql-Dockerfile
cd /docker/mysql
上传mysql-5.6.36.tar.gz软件包至目录内
tar xzvf mysql-5.6.36.tar.gz ##解压
vim Dockerfile
FROM docker.io/centos:7
RUN yum -y install gcc gcc-c++ make autoconf make cmake wget
RUN groupadd mysql; useradd -r -M -u 3306 -s /sbin/nologin -g mysql mysql
RUN mkdir /usr/local/mysql; mkdir /data/mysql -pv
RUN yum install gcc gcc-c++ ncurses-devel bison bison-devel -y
RUN wget -c http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.29.tar.gz
RUN tar xf mysql-5.6.36.tar.gz -C /usr/local/src/
WORKDIR /usr/local/src/mysql-5.6.36
RUN cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DEXTRA_CHARSETS=all -DDEFAULT_COLLATION=utf8_general_ci -DWITH-MYSQLD-LDFLAGS=-all-static -DWITH-CLIENT-LD-FLAGS=-all-static -DWITH_DEBUG=0 && gmake && gmake install
RUN chown -R root:mysql /usr/local/mysql/ && chown -R mysql:mysql /data/mysql
RUN chmod 755 /usr/local/src/mysql-5.6.36/scripts/mysql_install_db.sh
RUN /usr/local/src/mysql-5.6.36/scripts/mysql_install_db.sh --basedir=/usr/local/mysql --datadir=/data/mysql --no-defaults --user=mysql
RUN cp /usr/local/src/mysql-5.6.36/support-files/my-default.cnf /etc/my.cnf
RUN cp /usr/local/src/mysql-5.6.36/support-files/mysql.server /etc/init.d/mysqld
RUN chmod 775 /etc/init.d/mysqld && /etc/init.d/mysqld start
RUN echo -e '#!/bin/bash\\nexport PATH=$PATH:/usr/local/mysql/bin' >/etc/profile.d/mysql.sh
RUN source /etc/profile
EXPOSE 3306
5、构建mysql镜像和开启服务
docker build -t "centos:mysql-5.6" .
docker run -idt -p 3306:3306 --device-write-bps /dev/sda:10M 45949d7f9d2e /bin/bash
docker exec -it 04716b5e5b69 /bin/bash ##进入容器
/etc/init.d/mysqld start ##开启服务
6、进入数据库授权
mysqladmin -u root -p password ##创建数据库密码，123
mysql -uroot -p123 ##进入数据库
create database wordpress default charset utf8 COLLATE utf8_general_ci; ##创建wordpress 表
grant all privileges on wordpress.* to 'wordpress'@'%' identified by '123' with grant option; ##授权
flush privileges; ##刷新权限生效
exit ##退出数据库、退出容器
7、测试
访问网页wordpress
http://192.168.35.70/wordpress/wp-admin/install.php
发现页面报错：建立数据库连接时出错
docker inspect --format='{{.NetworkSettings.IPAddress}}' 04716b5e5b69 ##查询mysql的容器
172.17.0.4
docker exec -it 95e2167b5a54 /bin/bash ##进入容器
vi /usr/local/nginx/html/wordpress/wp-config.php ##修改密码，ip地址
再次访问即可
四、备份
1、将所有容器快照
[root@docker-lnmp ~]# docker ps ##查询容器
CONTAINER ID IMAGE COMMAND CREATED STATUS
04716b5e5b69 45949d7f9d2e "/bin/bash" 44 minutes ago Up 44 minutes

ebeac4fc952e centos:stress "/bin/bash" 8 hours ago Up 8 hours
[root@docker-lnmp ~]# docker images ##查询镜像
REPOSITORY TAG IMAGE ID CREATED SIZE

centos stress 1783b97c340a 8 hours ago 511MB
centos 7 8652b9f0cb4c 9 months ago 204MB
[root@docker-lnmp ~]# docker export 04716b5e5b69 > test.tar ##导出备份
[root@docker-lnmp ~]# docker export 95e2167b5a54 > test1.tar
[root@docker-lnmp ~]# cat test1.tar | docker import - centos:new ##导入

centos stress 1783b97c340a 8 hours ago 511MB
centos 7 8652b9f0cb4c 9 months ago 204MB
2.将镜像保存成tar包
[root@docker-lnmp ~]# docker save -o mysql.tar centos:mysql-5.6
[root@docker-lnmp ~]# docker save -o nginx-php.tar centos:nginx-php
[root@docker-lnmp ~]# docker ps

[root@docker-lnmp ~]# docker stop 95e2167b5a54 ##停止容器
95e2167b5a54
[root@docker-lnmp ~]# docker rm 95e2167b5a54 ##删除容器
95e2167b5a54
[root@docker-lnmp ~]# docker rmi dca610fe132c ##删除镜像
