docker怎样搭建php nginx swoole mysql redis环境-mile米乐体育
这篇文章给大家分享的是有关docker怎样搭建php nginx swoole mysql redis环境的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
软件:docker-ce version 18.09.3, docker-compose version 1.23.2
一.创建带有swoole-redis-pdo_mysql-gd扩展的docker image
1.创建dockerfile文件
vimdockerfile
2.在dockerfile文件写入
fromphp:7.1-fpm runapt-getupdate&&apt-getinstall-y\ libfreetype6-dev\ libjpeg62-turbo-dev\ libpng-dev\ &&docker-php-ext-install-j$(nproc)iconv\ &&docker-php-ext-configuregd--with-freetype-dir=/usr/include/--with-jpeg-dir=/usr/include/\ &&docker-php-ext-install-j$(nproc)gd\ &&docker-php-ext-configurepdo_mysql\ &&docker-php-ext-installpdo_mysql\ &&peclinstallredis-4.3.0\ &&peclinstallswoole\ &&docker-php-ext-enableredisswoole
3.创建自定义的php镜像,主要不要漏了最后的 '.',是指定当前目录构建镜像
dockerbuild-tmyphp4.
运行指令,由于网络问题等,需要等比较长的时间,成功后会出现类似下面的代码
...build process completed successfullyinstalling '/usr/local/include/php/ext/swoole/config.h'installing '/usr/local/lib/php/extensions/no-debug-non-zts-20160303/swoole.so'install ok: channel://pecl.php.net/swoole-4.3.1configuration option "php_ini" is not set to php.ini locationyou should add "extension=swoole.so" to php.iniremoving intermediate container ad1420f7554f---> 2f2f332d73cesuccessfully built 2f2f332d73cesuccessfully tagged myphp4:latest
至此docker 的自定义myphp4 image创建成功!
二.创建docker-compose.yml文件
mkdirpnsmr cdpnsmr vimdocker-compose.yml
写入下面代码
version:'3.0' services: nginx: image:"nginx:latest" ports: -"10000:80" volumes: -/var/www/html:/usr/share/nginx/html php-fpm: image:"myphp4" volumes: -/var/www/html:/usr/share/nginx/html mysql: image:"mysql:latest" redis: image:"redis:4.0"
运行指令
docker-composeup-d
成功可以看到
warning: the docker engine you're using is running in swarm mode.
compose does not use swarm mode to deploy services to multiple nodes in a swarm. all containers will be scheduled on the current node.
to deploy your application across the swarm, use `docker stack deploy`.
creating network "pnsmr_default" with the default drivercreating pnsmr_php-fpm_1 ... donecreating pnsmr_redis_1 ... donecreating pnsmr_mysql_1 ... donecreating pnsmr_nginx_1 ... done
至此,已开启nginx mysql redis php 服务
三.修改各服务配置文件
1.浏览器输入 127.0.0.1:9998 #此处应输入你的服务器ip地址,可以看到下图
2.接下来要修改容器里nginx的配置文件,先使用指令查看各容器的docker ip地址
dockerinspect-f'{{.name}}-{{range.networksettings.networks}}{{.ipaddress}}{{end}}'$(dockerps-aq)
此指令可以查看所有用docker-compose 开启的容器的ip,结果类似下图,可以用对应的ip地址进行内部通讯
3.复制nginx容器的配置文件出来,并修改替换,使nginx能解析php
dockercppnsmr_nginx_1:/etc/nginx/conf.d/default.confnginx.conf vimnginx.conf
修改为下列代码
server{ listen80; server_namelocalhost; #charsetkoi8-r; #access_log/var/log/nginx/host.access.logmain; location/{ root/usr/share/nginx/html; indexindex.htmlindex.htm; } #error_page404/404.html; #redirectservererrorpagestothestaticpage/50x.html # error_page500502503504/50x.html; location=/50x.html{ root/usr/share/nginx/html; } #proxythephpscriptstoapachelisteningon127.0.0.1:80 # #location~\.php${ #proxy_passhttp://127.0.0.1; #} #passthephpscriptstofastcgiserverlisteningon127.0.0.1:9000 # location~\.php${ roothtml; fastcgi_pass172.24.0.3:9000;#此处需要填写你的php容器的docker内部通讯ip fastcgi_indexindex.php; fastcgi_paramscript_filename/usr/share/nginx/html/$fastcgi_script_name; includefastcgi_params; } #denyaccessto.htaccessfiles,ifapache'sdocumentroot #concurswithnginx'sone # #location~/\.ht{ #denyall; #} } dockercpnginx.confpnsmr_nginx_1:/etc/nginx/conf.d/default.conf#将修改好的配置文件拷贝到容器里 dockercontainerstoppnsmr_nginx_1 dockercontainerstartpnsmr_nginx_1#重启nginx容器使配置文件生效 vim/var/www/html/index.php#在服务器本地目录新建index.php文件,输入访问127.0.0.1:9998, html文件解析正常
访问127.0.0.1:9998/index.php,php文件解析正常
4.测试mysql,redis是否生效
vim/var/www/html/redis.php#用于测试redis是否配置成功 connect("172.24.0.4",6379); $redis->set('test','thisisatestforredis'); echo$redis->get('test');访问127.0.0.1:9998/redis.php,redis已生效
进入mysql容器
dockerexec-itpnsmr_mysql_1bash进入mysql并更改root用户密码
创建测试文件
vim/var/www/html/mysql.php访问127.0.0.1:9998/mysql.php,mysql已生效
四.总结
虽然环境是配置成功了,并可以用docker-compose up 指令一键生成,但是还要改各容器的配置文件,仍然不够方便,需要优化;另外docker的集群,堆栈功能也没用上,后面再继续学习.
