2021Docker容器技术全解-使用Dockerfile打包Nginx+php镜像(6)

Dockerfile语法：

MAINTAINER:镜像创建者信息
EXPOSE:开放的端口
ENV:设置变量
WORKDIR:定义容器默认工作目录，相当于cd到某个目录
CMD:容器启动时执行的命令，仅可以有一条CMD

一，在m01虚拟机中的准备工作-使用dockerfile自定义镜像Nginx+php

1先在容器内手动安装阿帕奇：

#1进入容器
[root@web01 ~]#docker run -it mycentos8:v20211229
#2安装阿帕奇
[root@e81ffc0059aa /]# yum -y install httpd
#3查看启动文件看看阿帕奇是如何启动的
[root@e81ffc0059aa ~]# cat /lib/systemd/system/httpd.service

[Unit]
Description=The Apache HTTP Server
Wants=httpd-init.service
After=network.target remote-fs.target nss-lookup.target httpd-init.service
Documentation=man:httpd.service(8)

[Service]
Type=notify
#环境变量
Environment=LANG=C
#执行启动命令
ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND
ExecReload=/usr/sbin/httpd $OPTIONS -k graceful
# Send SIGWINCH for graceful stop
KillSignal=SIGWINCH
KillMode=mixed
PrivateTmp=true

[Install]
WantedBy=multi-user.target
[root@e81ffc0059aa ~]#

4启动阿帕奇
[root@e81ffc0059aa ~]# LANG=C
[root@e81ffc0059aa ~]# /usr/sbin/httpd $OPTIONS -k graceful
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message
httpd not running, trying to start

[root@e81ffc0059aa ~]# /usr/sbin/httpd $OPTIONS -DFOREGROUND
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message
httpd (pid 73) already running

#查看执行历史
[root@e81ffc0059aa ~]# history
   19  yum -y install httpd
   20  systemctl start httpd
   21  pstree -p
   27  cat /lib/systemd/system/httpd.service
   28  LANG=C
   30  /usr/sbin/httpd $OPTIONS -DFOREGROUND
[root@e81ffc0059aa ~]#

2编写dockerfile：

[root@web01 ~]#mkdir bb
[root@web01 ~]#cd bb
[root@web01 ~/bb]#touch Dockerfile
[root@web01 ~/bb]#vim Dockerfile 
[root@web01 ~/bb]#cat Dockerfile 
FROM mycentos8:v20211229
RUN yum -y install httpd
ENV LANG=C
#指定开放的端口
EXPOSE 80 443
#设置默认的工作目录
WORKDIR /var/www/html
#拷贝文件到指定目录
ADD index.html /var/www/html/index.html
#cmd特定语法格式例如ls -la: CMD ["ls","-l","-a"]
CMD ["/usr/sbin/httpd", "-DFOREGROUND"]

3创建html文件

[root@web01 ~/bb]#vim index.html
[root@web01 ~/bb]#pwd
/root/bb

4执行dockerfile创建阿帕奇服务镜像

[root@web01 ~/bb]#docker build -t mycentos8:httpd .

5基于镜像构建容器：

[root@web01 ~/bb]#docker run --name httpd -d -p 80:80 mycentos8:httpd

6验证：

#查看容器
[root@web01 ~/bb]#docker ps
CONTAINER ID   IMAGE             COMMAND                  CREATED         STATUS         PORTS                                        NAMES

#查看容器详细信息
[root@web01 ~/bb]#docker inspect f8361cb098b0

 "IPAddress": "172.17.0.2",
#模拟浏览器访问 
[root@web01 ~/bb]#curl 172.17.0.2
hello world!

制作一个nginx+php的镜像

制作思路：

1在虚拟机中手工安装所有服务(yum+编译)
解决方案：记录所有程序运行的"依赖包"
2验证配置，打包安装路径
解决方案：把编译好的软件直接放入容器内
在虚拟机里编译安装软件，然后对软件安装后的文件夹进行打包，
3多服务
解决方案：启动脚本
dockerfile的cmd只能启动一条命令，那么我们通过启动一个脚本即可实现启动很多命令

1清除历史命令：

[root@m01 ~]#history -c
[root@m01 ~]#history -w
[root@m01 ~]#

2上传nginx软件包安装依赖环境：

[root@m01 ~]#ls
anaconda-ks.cfg  nginx-1.20.1.tar.gz
[root@m01 ~]#yum install gcc make pcre-devel openssl-devel -y

3安装php后端执行环境需要用到的四个软件包以及后面需要用到的压缩文件

[root@m01 ~]#yum install pcre openssl php php-fpm bzip2 -y

4添加nginx用户：

[root@m01 ~]#useradd nginx

5编译安装nginx

[root@m01 ~]#tar xf nginx-1.20.1.tar.gz 
[root@m01 ~]#cd nginx-1.20.1/
[root@m01 ~/nginx-1.20.1]#./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module
[root@m01 ~/nginx-1.20.1]#make && make install

6修改nginx配置文件让nginx支持php（把下面的注释取消）

[root@m01 ~/nginx-1.20.1]#vim /usr/local/nginx/conf/nginx.conf

location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            #include        fastcgi_params; #注释掉
            include        fastcgi.conf; #新添加
        }

7手工启动php

1)查看php启动文件查看启动命令：

[root@m01 /user/local/nginx]#cat /lib/systemd/system/php-fpm.service
# It's not recommended to modify this file in-place, because it
# will be overwritten during upgrades.  If you want to customize,
# the best way is to use the "systemctl edit" command.

[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target

[Service]
Type=notify
#--nodaemonize &表示放后台运行
ExecStart=/usr/sbin/php-fpm --nodaemonize #--nodaemonize表示放前台运行
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true
RuntimeDirectory=php-fpm
RuntimeDirectoryMode=0755

[Install]
WantedBy=multi-user.target

2)启动php

#启动
[root@m01 /usr/local/nginx/conf]#/usr/sbin/php-fpm --nodaemonize &
[1] 16905
[root@m01 /usr/local/nginx/conf]#[30-Dec-2021 09:19:42] ERROR: unable to bind listening socket for address '/run/php-fpm/www.sock': No such file or directory (2)
[30-Dec-2021 09:19:42] ERROR: FPM initialization failed
^C
[1]+  退出 78               /usr/sbin/php-fpm --nodaemonize

#解决报错
[root@m01 /usr/local/nginx/conf]#mkdir -p /run/php-fpm/
#启动
[root@m01 /usr/local/nginx/conf]#/usr/sbin/php-fpm --nodaemonize &
[1] 16907
[root@m01 /usr/local/nginx/conf]#[30-Dec-2021 09:20:09] NOTICE: fpm is running, pid 16907
[30-Dec-2021 09:20:09] NOTICE: ready to handle connections
[30-Dec-2021 09:20:09] NOTICE: systemd monitor interval set to 10000ms
#查看运行端口
[root@m01 /usr/local/nginx/conf]#ss -ltun

3）检查php端口（最后发现走的是socket模式）

[root@m01 /usr/local/nginx/conf]#netstat -ntulp |grep 9000
[root@m01 /usr/local/nginx/conf]#ss -lntup |grep php
[root@m01 /usr/local/nginx/conf]#find / -name www.conf
/etc/php-fpm.d/www.conf
[root@m01 /usr/local/nginx/conf]#cat /etc/php-fpm.d/www.conf |egrep -v ";"
[www]
user = apache
group = apache
listen = /run/php-fpm/www.sock
listen.acl_users = apache,nginx
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
slowlog = /var/log/php-fpm/www-slow.log
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path]    = /var/lib/php/session
php_value[soap.wsdl_cache_dir]  = /var/lib/php/wsdlcache

4）启动nginx

[root@m01 /usr/local/nginx]#/usr/local/nginx/sbin/nginx
[root@m01 /usr/local/nginx]#ps -ef|grep nginx
root       16990       1  0 09:51 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nginx      16991   16990  0 09:51 ?        00:00:00 nginx: worker process
root       16993    1706  0 09:51 pts/0    00:00:00 grep --color=auto nginx

5）验证nginx是否已经解析php了（报错）：

#1先写个php信息函数
[root@m01 /usr/local/nginx/html]#ls
50x.html  index.html
[root@m01 /usr/local/nginx/html]#vim info.php

<?PHP
    phpinfo();
?>

#2模拟浏览器
curl http://127.0.0.1   #正常
curl http://127.0.0.1/info.php #不能访问
也就是说：nginx配置出问题了

6）修改nginx配置

[root@m01 /usr/local/nginx/conf]#cat nginx.conf

location ~ \.php$ {
            root             html;
        fastcgi_pass     unix:/run/php-fpm/www.sock;
        fastcgi_index    index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include fastcgi_params;
        }

7）重启nginx访问测试正常

[root@m01 /usr/local/nginx/conf]#/usr/local/nginx/sbin/nginx -s reload
curl http://127.0.0.1/info.php #访问正常

8停掉nginx并删掉没用的目录

#停掉nginx
[root@m01 /usr/local/nginx/conf]#/usr/local/nginx/sbin/nginx -s stop
[root@m01 /usr/local/nginx/conf]#ss -lntup
#删掉没用的目录
[root@m01 /usr/local/nginx]#ls
client_body_temp  conf  fastcgi_temp  html  logs  proxy_temp  sbin  scgi_temp  uwsgi_temp
[root@m01 /usr/local/nginx]#rmdir *_temp
#剩下的就是编译前原本的目录：
[root@m01 /usr/local/nginx]#ls
conf  html  logs  sbin

9对nginx目录进行打包：

#安装打包文件
[root@m01 /usr/local/nginx]#yum install bzip2 -y
#打包bzip2文件
[root@m01 /usr/local/nginx]#cd ../
[root@m01 /usr/local]#tar -cjf nginx.tar.bz2 nginx
[root@m01 /usr/local]#ls
bin  etc  games  include  lib  lib64  libexec  nginx  nginx.tar.bz2  sbin  share  src

10把打包文件拷贝到web01上；

[root@m01 /usr/local]#scp nginx.tar.bz2 10.0.0.7:./

11查看历史命令看看安装nginx的全部过程：

[root@m01 /usr/local]#history
    1  history -w
    2  rz
    3  ls
    4  yum install gcc make pcre-devel openssl-devel -y
    5  yum install pcre openssl php php-fpm -y
    6  useradd nginx
    7  ls
    8  tar xf nginx-1.20.1.tar.gz 
    9  cd nginx-1.20.1/
   10  ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module
   11  make && make install
   12  cd /usr/local/nginx
   13  ls
   14  cd conf
   15  ls
   16  vim nginx.conf
   17  cat /lib/systemd/system/php-fpm.service
   18  /usr/sbin/php-fpm --nodaemonize &
   19  mkdir -p /var/run/
   20  /usr/sbin/php-fpm --nodaemonize &
   21  mkdir -p /run/php-fpm/
   22  /usr/sbin/php-fpm --nodaemonize &
   23  ss -ltun
   24  lsof -i:9000
   25  /usr/sbin/php-fpm --nodaemonize &
   26  curl 127.0.0.1:9000
   27  cat /usr/local/nginx/conf/nginx.conf
   28  ls
   29  cat fastcgi.conf
   30  ps -ef|grep php=fpm
   31  ps -ef|grep php-fpm
   32  netstat -ntulp |grep 80
   33  netstat -ntulp |grep 9000
   34  netstat -ntulp |grep 22
   35  ss -lntup |grep php
   36  rpm -qa |grep php
   37  find / -name www.conf
   38  cat /etc/php-fpm.d/www.conf
   39  cat /etc/php-fpm.d/www.conf |grep -v ;
   40  cat /etc/php-fpm.d/www.conf |grep -v ^;
   41  cat /etc/php-fpm.d/www.conf |grep "^\s*[^# \t].*$"
   42  cat /etc/php-fpm.d/www.conf |egrep -v "^\s*[^# \t].*$"
   43  cat /etc/php-fpm.d/www.conf |egrep -v ";"
   44  netstat -ntulp |grep 9000
   45  ss -lntup |grep php
   46  find / -name www.conf
   47  ls
   48  cd ../
   49  ls
   50  pwd
   51  /usr/local/nginx/sbin/nginx
   52  ps -ef|grep nginx
   53  ls
   54  cd html
   55  ls
   56  vim info.php
   57  curl http://127.0.0.1
   58  curl http://127.0.0.1/info.php
   59  vim info.php
   60  cd ../
   61  cd conf
   62  ls
   63  vim nginx.conf
   64  nginx -s reload
   65  /bin/kill -USR2 $MAINPID
   66  /usr/local/nginx/sbin/nginx -s reload
   67  curl http://127.0.0.1/info.php
   68  vim nginx.conf
   69  curl http://127.0.0.1/info.php
   70  /usr/local/nginx/sbin/nginx -s reload
   71  curl http://127.0.0.1/info.php
   72  vim nginx.conf
   73  /usr/local/nginx/sbin/nginx -s reload
   74  curl http://127.0.0.1/info.php
   75  vim nginx.conf
   76  /usr/local/nginx/sbin/nginx -s reload
   77  curl http://127.0.0.1/info.php
   78  curl http://127.0.0.1
   79  curl http://127.0.0.1/info.php
   80  vim nginx.conf
   81  /usr/local/nginx/sbin/nginx -s reload
   82  vim nginx.conf
   83  /usr/local/nginx/sbin/nginx -t
   84  /usr/local/nginx/sbin/nginx -s reload
   85  curl http://127.0.0.1/info.php
   86  cat nginx.conf
   87  /usr/local/nginx/sbin/nginx -s stop
   88  ss -lntup
   89  cd ../
   90  ls
   91  rmdir *_temp
   92  ls
   93  yum install bzip2
   94  cd ../
   95  tar -cjf nginx.tar.bz2 nginx
   96  ls
   97  scp nginx.tar.bz2 10.0.0.7:./
   98  history
[root@m01 /usr/local]#

至此前期的准备工作到这里为止就准备好了！

但由于上面的过程中出现了报错和各种试错，步骤很乱，下面开始恢复虚拟机快照从新再走一遍，以便整理出清晰的步骤：

[root@m01 /usr/local]#history
    1  history -w
    2  rz
    3  ls
    4  yum install gcc make pcre-devel openssl-devel -y
    5  yum install pcre openssl php php-fpm bzip2 -y
    6  useradd nginx
    7  mkdir -p /run/php-fpm/
    8  tar xf nginx-1.20.1.tar.gz
    9  cd nginx-1.20.1/
   10  ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module
   11  make && make install
   12  vim /usr/local/nginx/conf/nginx.conf
   13  cat /lib/systemd/system/php-fpm.service
   14  /usr/sbin/php-fpm --nodaemonize &
   15  ps -ef|grep php-fpm
   16  cat /etc/php-fpm.d/www.conf |egrep -v ";"
   17  /usr/local/nginx/sbin/nginx
   18  ps -ef|grep nginx
   19  cd /usr/local/nginx/html
   20  vim info.php
   21  curl http://127.0.0.1
   22  curl http://127.0.0.1/info.php
   23  /usr/local/nginx/sbin/nginx -s stop
   24  ps -ef|grep nginx
   25  cd /usr/local/nginx
   26  ls
   27  rmdir *_temp
   28  ls
   29  cd ../
   30  tar -cjf nginx.tar.bz2 nginx
   31  ls
   32  scp nginx.tar.bz2 10.0.0.7:./
   33  history
[root@m01 /usr/local]#

二，在web02中正式开始-使用dockerfile自定义镜像Nginx+php

1在压缩文件同目录下创建Dockerfile文件编写dockerfile

[root@web01 ~]#ls
aa  anaconda-ks.cfg  bb  busybox.tar  centos.tar  nginx.tar  nginx.tar.bz2  redis.tar  ubuntu.tar
[root@web01 ~]#mkdir cc
[root@web01 ~]#mv nginx.tar.bz2  cc/
[root@web01 ~]#cd cc
[root@web01 ~/cc]#touch Dockerfile
[root@web01 ~/cc]#vim Dockerfile 

FROM mycentos8:v20211229
RUN yum install -y pcre openssl php php-fpm && useradd nginx && mkdir -p /run/php-fpm/
#把软件包拷贝到指定目录下,ADD会自动解压
ADD nginx.tar.bz2 /usr/local/
#拷贝启动脚本
ADD run.sh /etc/init.d/run.sh
#执行启动命令
CMD ["/etc/init.d/run.sh"]

2解释为什么Dockerfile文件只有几步：

因为我们打包好的nginx已经编译过了，所以我们无需再编译了，因此下面编译的这些代码可不要

tar xf nginx-1.20.1.tar.gz
    9  cd nginx-1.20.1/
   10  ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module
   11  make && make install

又因为我们在打包时已经把nginx配置好了，所以配置文件这段代码也可以不要：

12  vim /usr/local/nginx/conf/nginx.conf

编写info.php测试文件已经打包的过程也不需要了

20  vim info.php
   21  curl http://127.0.0.1
   22  curl http://127.0.0.1/info.php
   23  /usr/local/nginx/sbin/nginx -s stop
   24  ps -ef|grep nginx
   25  cd /usr/local/nginx
   26  ls
   27  rmdir *_temp
   28  ls
   29  cd ../
   30  tar -cjf nginx.tar.bz2 nginx
   31  ls
   32  scp nginx.tar.bz2 10.0.0.7:./
   33  history

我们在编译软件包时需要的依赖我们也不需要了，因为我们打包的目录已经编译完毕了

yum install gcc make pcre-devel openssl-devel -y

最后还剩下如下步骤：

useradd nginx
mkdir -p /run/php-fpm/
/usr/sbin/php-fpm --nodaemonize &

3编写dockerfile里需要的启动脚本文件：

注意脚本启动完毕就自动退出了，脚本一退出，服务就终止了，所以编写脚本时要考虑如何让nginx一直运行下去

[root@web01 ~/cc]#vim run.sh
[root@web01 ~/cc]#cat run.sh
#!/bin/bash
useradd nginx
mkdir -p /run/php-fpm/
/usr/sbin/php-fpm --nodaemonize &
#启动nginx不让nginx随着脚本退出而退出
/usr/local/nginx/sbin/nginx -g "daemon off;"
[root@web01 ~/cc]#chmod 755 run.sh

4因为nginx是个服务，所以我们还需要把监听端口加进去：

[root@web01 ~/cc]#vim Dockerfile 

FROM mycentos8:v20211229
RUN yum install -y pcre openssl php php-fpm && useradd nginx && mkdir -p /run/php-fpm/
#把软件包拷贝到指定目录下,ADD会自动解压
ADD nginx.tar.bz2 /usr/local/
#拷贝启动脚本
ADD run.sh /etc/init.d/run.sh
#nginx监听端口
EXPOSE 80
#执行启动命令
CMD ["/etc/init.d/run.sh"]

5测试运行（未打包成功）

[root@web01 ~/cc]#docker build -t mycentos8:nginx .

6修改dockerfile文件：

[root@web01 ~/cc]#cat Dockerfile 
FROM mycentos8:v20211229
RUN yum install -y pcre openssl php php-fpm && mkdir -p /run/php-fpm/
#把软件包拷贝到指定目录下,ADD会自动解压
ADD nginx.tar.bz2 /usr/local/
#拷贝启动脚本
ADD run.sh /etc/init.d/run.sh
#nginx监听端口
EXPOSE 80
#执行启动命令
CMD ["/etc/init.d/run.sh"]

7再次执行打包成功：

[root@web01 ~/cc]#docker build -t mycentos8:nginx .
[root@web01 ~/cc]#docker images
REPOSITORY   TAG         IMAGE ID       CREATED          SIZE
mycentos8    nginx       c757fb615c03   11 seconds ago   383MB

8测试：

1）启动镜像

#启动镜像
[root@web01 ~/cc]#docker run -itd mycentos8:nginx
4b6f222e1de5ea7880cd89dde9b65dfed0f4f552afadd038e74fbb5324ae757b
#进入容器
[root@web01 ~/cc]#docker exec -it 4b6f /bin/bash
[root@4b6f222e1de5 /]#

如果容器无法进入可用下列方法进行调试：

[root@web01 ~/cc]#docker run -it mycentos8:nginx /bin/bash
[root@2a07190a6dda /]# /etc/init.d/run.sh

2）进入容器测试：

[root@web01 ~/cc]#docker ps

exit

3退出容器测试：

[root@web01 ~/cc]#curl http://172.17.0.3
[root@web01 ~/cc]#curl http://172.17.0.3/info.php

至此，双服务镜像nginx+php-fpm就已经做好了

总结：

使用Dockerfile打包Nginx+php镜像： 1编译环境复杂，可以提前做好软件包，不需要再容器里编译

2启动任务多，可以使用脚本，完成所有工作
