Dockerfile搭建lnmp-CSDN博客

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
#关闭防火墙和核心防护
 
docker pull centos:7
#从docker Hub公共仓库下载基础镜像
 
docker network create --subnet=172.18.0.0/16 --opt "com.docker.network.bridge.name"="docker1" mynetwork
 
#设置自定义网络模式模式为bridge模式docker1的ip地址为172.18.0.1显示的网络名称mynetwork。
 
docker network ls
#查看使用的网络模式
 
ifconfig
##查看是否成功
 
mkdir /opt/nginx
mkdir /opt/mysql
mkdir /opt/php             ##创建工作目录

二、部署nginx容器172.18.0.10

1.编写Dockerfile构建镜像

FROM centos:7 AS first
 #使用centos:7镜像作为底层镜像
 
MAINTAINER this is nginx image <dhj 20231021>
 #管理员信息可不写
 
ADD nginx-1.24.0.tar.gz /opt/
 #上传安装包至容器/opt目录
 
RUN yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make && \
useradd -M -s /sbin/nologin nginx && \
cd /opt/nginx-1.24.0 && \
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module && \
make && \
make install
 #编译安装nginx
 
 
FROM centos:7
COPY --from=first /usr/local/nginx/ /usr/local/nginx/
 #多层构建使用上层镜像作为底层镜像减小镜像体积
 
RUN useradd -M -s /sbin/nologin nginx
 #创建nginx用户
 
EXPOSE 80
EXPOSE 443
 #开启80443端口
 
CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]
 #指定nginx前台启动

2.准备nginx配置文件

#user  nobody;
worker_processes  2;
 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
 
#pid        logs/nginx.pid;
 
 
events {
    use epoll;
    worker_connections  1024;
}
 
 
http {
    include       mime.types;
    default_type  application/octet-stream;
 
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';
 
    #access_log  logs/access.log  main;
 
    sendfile        on;
    #tcp_nopush     on;
 
    #keepalive_timeout  0;
    keepalive_timeout  65;
 
    #gzip  on;
 
    server {
        listen       80;
        server_name  www.wzw.com;
 
        charset utf-8;
 
        #access_log  logs/host.access.log  main;
 
        location / {
            root   html;
            index  index.php index.html;  #添加.php结尾的默认文件名
        }
 
        #error_page  404              /404.html;
 
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        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;
        #}
 
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {                     #开启fastcgi接口
            root           html;
            fastcgi_pass   172.18.0.30:9000;    #指定php信息
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;
            include        fastcgi_params;
        }
 
        # 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
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;
 
    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
 
 
    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;
 
    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
 
}

3.构建镜像启动nginx容器

docker build -t nginx:lnmp .
#构建nginx镜像(别忘记最后的点)
 
docker images
#查看镜像
 
docker run -d --name nginx -p 80:80 -v /opt/nginx/html/:/usr/local/nginx/html/ -v /opt/nginx/nginx.conf:/usr/local/nginx/conf/nginx.conf -m 500m --memory-swap 1g --net mynetwork --ip 172.18.0.10 nginx:lnmp
#启动容器
----------------------------
-m 500: #表示该容器内存最大为500MB
--memory-swap: #表示内存+swap总共1G那swap也是500MB
//相当于是限制了内存的使用量避免所占资源太多

三、部署mysql容器172.18.0.20

1. 编写Dockerfile构建镜像

FROM centos:7 AS first
MAINTAINER this is mysql image <dhj 20231021>
ADD mysql-boost-5.7.41.tar.gz /opt/
RUN yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake make openssl-devel && \
cd /opt/mysql-5.7.41/ && \
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8  \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=boost \
-DWITH_SYSTEMD=1 && make -j 2 && make install
 
FROM centos:7
COPY --from=first /usr/local/mysql/ /usr/local/mysql/
ADD my.cnf /etc/my.cnf
ENV PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
RUN useradd -M -s /sbin/nologin  mysql && \
chown mysql:mysql /etc/my.cnf && \
chown -R mysql:mysql /usr/local/mysql/ && \
/usr/local/mysql/bin/mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data  #重置数据库
EXPOSE 3306
CMD ["/usr/local/mysql/bin/mysqld"]  #前台启动mysql

2.准备mysql配置文件

[client]
port = 3306
socket=/usr/local/mysql/mysql.sock
 
[mysql]
port = 3306
socket = /usr/local/mysql/mysql.sock
auto-rehash
 
[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1
 
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES

3.构建镜像启动mysql容器

docker build -t mysql:lnmp .
#生成镜像
 
 
docker run --name mysql -d --privileged --device-write-bps /dev/sda:10M -v /usr/local/mysql --net mynetwork --ip 172.18.0.20 mysql:lnmp
#启动镜像
 
-----------------------------------------
--privileged: #让容器内拥有root权限
--device-write-bps: #限制写入到/dev/sda中每秒最大10M的速度。
-v /usr/local/mysql: #共享这个目录其它容器可以使用--volumes-from 指定读取本容器的共享目录。然后也会生成一样的目录。
--net mynetwork: #指定--net网络模式mynetwork为自定义网络模式。
--ip 172.18.0.20: #指定ip地址自定义网络模式也可以指定ip地址。
-----------------------------------------
docker ps -a
#查看容器

四、部署php容器172.18.0.30

1. 编写Dockerfile构建镜像

FROM centos:7 AS first
MAINTAINER this is php image <dhj 20231021>
ADD php-7.1.10.tar.bz2 /opt/
RUN yum -y install gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel \
gcc gcc-c++ make pcre-devel && \
cd /opt/php-7.1.10/ && \
./configure \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip && make -j 2 && make install && \
cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini && \
sed -i -e '939c date.timezone = Asia/Shanghai'  -e '1170c mysqli.default_socket = /usr/local/mysql/mysql.sock' /usr/local/php/lib/php.ini && \ 
 #更改php.ini配置
cd /usr/local/php/etc/ && \
cp  php-fpm.conf.default php-fpm.conf && \
sed -i '17 s/^;//' php-fpm.conf && \
cd /usr/local/php/etc/php-fpm.d/ && \
cp www.conf.default www.conf && \
sed -i -e '23c user = nginx' -e '24c group = nginx' -e '36c listen = 172.18.0.30:9000' -e '62c listen.allowed_clients = 172.18.0.10' www.conf
 #更改php-fpm.conf配置
 
FROM centos:7    #使用多级构建
COPY --from=first /usr/local/php/ /usr/local/php/
RUN yum -y install gd \
libjpeg-devel \
libpng-devel \
freetype-devel \
libxml2-devel \
zlib-devel \
curl-devel \
openssl-devel && \
useradd -M -s /sbin/nologin nginx && \
rm -rf /var/cache/yum/*
 #清理容器中yum缓存减小容器体积
EXPOSE 9000
CMD ["/usr/local/php/sbin/php-fpm", "-F"]

2.构建镜像启动php容器

由于在Dockerfile中更改了配置文件内容所以不需要自己准备配置文件

也可以自己准备好配置文件使用copy复制到容器中

docker build -t php:lnmp .
#构建镜像
 
docker run -d --name php --net mynetwork --ip 172.18.0.30 -p 9000:9000 --volumes-from nginx --volumes-from mysql php:lnmp
#启动容器
-----------------------------------------------
--volumes-from nginx:  #表示读取nginx容器的共享信息
--volumes-from mysql:  #表示读取mysql容器的共享信息
-----------------------------------------------
 
docker ps -a
#查看容器

五、启动wordpress服务

1. 登录到mysql容器中授权:

docker exec -it mysql bash
#登录到mysql容器
 
mysql 
#登录到容器中
 
create database wordpress;
#创建一个数据库
 
grant all privileges on wordpress.* to 'wordpress'@'%' identified by 'abc123';
#授权
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
 
flush privileges;
#刷新
