php容器启动参数说明
-d 让容器运行在后台
-p 添加主机到容器的端口映射
-v 添加目录映射，这里最好nginx容器的根目录最好写成和php容器中根目录一样。但是不一定非要一样,如果不一样在配置nginx的时候需要注意
-name 容器的名称
-link 容器之间建立起来联系 （需要建立联系的容器名:mysql）
2.3 php的扩展安装
- 安装php-redis
进入php容器
docker exec -it php bash
安装php-redis命令
pecl install redis && docker-php-ext-enable redis
[root@localhost ~]# docker exec -it php bash
root@7750e24826b7:/var/www/html# pecl install redis && docker-php-ext-enable redis

3.1 获取nginx:1.14镜像
[root@localhost ~]# docker pull nginx:1.14
1.14: Pulling from library/nginx
27833a3ba0a5: Pull complete
0f23e58bd0b7: Pull complete

Digest: sha256:f7988fb6c02e0ce69257d9bd9cf37ae20a60f1df7563c3a2a6abe24160306b8d
Status: Downloaded newer image for nginx:1.14
3.2 启动nginx容器
- 新建nginx挂载目录
[root@localhost ~]# mkdir -p /opt/app/nginx/{conf,html,logs,cert}
- 编写nginx主配置文件
[root@localhost ~]# cd /opt/app/nginx/[root@localhost nginx]# vim nginx.confworker_processes 4;
user nginx;
#pid /opt/app/nginx/sbin/nginx.pid;
events {worker_connections 409600;
}
http {include mime.types;default_type application/octet-stream;server_tokens off;autoindex on;autoindex_exact_size off;autoindex_localtime on;keepalive_timeout 65;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 /var/log/nginx/access.log main;error_log /var/log/nginx/error.log error;include /etc/nginx/conf.d/*.conf;
}- 编写nginx容器启动脚本
[root@localhost nginx]# pwd
/opt/app/nginx[root@localhost nginx]# vim nginx-run.sh
#!/bin/bashdocker run -itd --restart=unless-stopped -v /etc/localtime:/etc/localtime -v /etc/timezone:/etc/timezone -p 80:80 --name nginx -v /opt/app/nginx/html:/usr/share/nginx/html -v /opt/app/nginx/logs:/var/log/nginx -v /opt/app/nginx/cert:/etc/nginx/cert -v /opt/app/nginx/nginx.conf:/etc/nginx/nginx.conf -v /opt/app/nginx/conf:/etc/nginx/conf.d --link php:phpfpm nginx:1.14参数解释：
-v 添加目录映射，这里nginx容器的静态页目录最好和php容器中静态页目录映射的目录一致。但是不一定非要一样,如果不一样在配置nginx的时候需要注意
–link 容器之间建立起来联系,此处nginx需要与php容器建立联系(写法：php容器名称:phpfpm)，此参数必须写在使用镜像名称之前。
- 为启动脚本赋予执行权限
[root@localhost nginx]# chmod +x nginx-run.sh [root@localhost nginx]# ll nginx-run.sh
-rwxr-xr-x 1 root root 393 8月 6 16:28 nginx-run.sh
- 启动nginx容器
[root@localhost nginx]# ./nginx-run.sh
850e27b026be83886f2deee90d8b36754eb29eeffd1e27e18a6e5724bc29f3f7
- 查看nginx容器启动情况
[root@localhost nginx]# docker ps -a --no-trunc --filter name=nginx$
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
850e27b026be83886f2deee90d8b36754eb29eeffd1e27e18a6e5724bc29f3f7 nginx:1.14 "nginx -g 'daemon off;'" 30 seconds ago Up 29 seconds 0.0.0.0:80->80/tcp nginx
3.3 编写nginx虚拟主机配置文件，使其支持php
[root@localhost conf]# pwd
/opt/app/nginx/conf[root@localhost conf]# vim nginx-php.conf server {listen 80;server_name 10.20.29.36;location / {root /usr/share/nginx/html;index index.php index.html index.htm;}location ~ \.php$ {root html;fastcgi_pass 10.20.29.36:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME /var/www/html/$fastcgi_script_name;include fastcgi_params;}access_log /var/log/nginx/access.php.log main;}
注意！！！
location / {root /usr/share/nginx/html; //修改这里的默认路径为nginx静态页面路径
fastcgi_pass 10.20.29.93:9000;
#这里可以用容器ID,容器名称，容器IP+端口或者宿主机IP+端口，都可以找到php服务
即：fastcgi_pass 7750e24826b7/php/172.17.0.3/10.20.29.93:9000;
- 进入到容器里面重新加载配置文件
[root@localhost conf]# docker exec -it nginx bash #进入nginx容器
root@850e27b026be:/# nginx -t #nginx检测配置文件是否正确
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
root@850e27b026be:/# nginx -s reload #平滑重启nginx，不影响nginx服务使用3.4 php测试静态页编写
在主机/opt/app/nginx/html 目录下创建php测试页面，会直接映射到容器里面
[root@localhost html]# pwd
/opt/app/nginx/html[root@localhost html]# vim index.php<?phpinfo();
?>四、访问浏览器测试
看到php静态测试页面说明搭建成功了！
