[docker部署php环境]
apache模式
docker run -it --rm --name my-apache-php-app -p 8000:80 -v "$PWD":/var/www/html php:5.4-apache
fpm模式配置过程
docker run -it --rm --name my-fpm-php-app -p 9000:9000 -v "$PWD":/var/www/html php:5.4-fpm
配置nginx（物理机部署）
编辑/etc/nginx/sites-available/default ，添加如下行
location ~* \.php$ {
fastcgi_index index.php;
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
}
nginx -s reload
nginx container + fpm模式
1.启动fpm容器
docker run -d --name my-fpm-php-app -v /root/src:/var/www/html php:5.4-fpm
2.启动nginx服务器并link到fpm
docker run --name my-nginx -d -p 8080:80 --link my-fpm-php-app:fpm nginx
3.查看fpm的ip地址及端口号
docker exec -it my-nginx "/bin/bash"
进入后使用env命令查看环境变量，输出如下，可以看到fpm对应的ip及端口号
root@05cb669a483f:/# envFPM_PORT_9000_TCP_ADDR=172.17.0.20HOSTNAME=05cb669a483fFPM_PORT_9000_TCP_PORT=9000FPM_NAME=/my-nginx/fpmFPM_PORT_9000_TCP_PROTO=tcpFPM_ENV_PHP_INI_DIR=/usr/local/etc/phpFPM_ENV_PHP_VERSION=5.4.45PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binPWD=/NGINX_VERSION=1.9.5-1~jessieFPM_ENV_GPG_KEYS=F38252826ACD957EF380D39F2F7956BC5DA04B5DFPM_PORT=tcp://172.17.0.20:9000SHLVL=1HOME=/rootFPM_PORT_9000_TCP=tcp://172.17.0.20:9000FPM_ENV_PHP_EXTRA_CONFIGURE_ARGS=--enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data_=/usr/bin/env
4.修改容器中/etc/nginx/conf.d/default.conf文件，在容器内不能修改，先复制到本地后修改
docker cp my-nginx:/etc/nginx/conf.d/default.conf ./default.conf
修改内容如下
location ~* \.php$ { fastcgi_index index.php; fastcgi_pass 172.17.0.20:9000; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name;}
docker cp ./default.conf my-nginx:/etc/nginx/conf.d/default.conf
5.reload 容器中的nginx
docker exec -it my-nginx "/bin/bash"
在容器中执行nginx -s reload
备注：访问过程中可能会报错：”File not found“，解决办法是吧default.conf 文件中
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
替换为绝对路径
fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
思路一：link时 nignx容器内会有fpm相关的环境变量，如何利用环境变量？sed 控制变量值读取环境变量
思路二：以fpm为baseimage，集成nginx，使用Supervisor或CFEngine同时吊起多个进程
使用Supervisor，容器内同时启动nginx以及fpm
root用户下新建目录
mkdir nginx-fpm
cd nginx-fpm
创建文件default.conf用来取代nginx默认配置文件
