EC2でphp環境構築 ① Nginx + php56 + php56-fpm + virtualhost

Last updated at Posted at 2015-09-28

概要

サーバー構築の経験があんまりにもないので、今回やってみた流れをまとめてみた。

目次

  • nginxインストール
  • php及びphp-fpmインストール
  • バーチャル環境構築

####### EC2 IP Adress(仮)

52.111.111.111

nginxインストール

EC2へログイン

[hoge@local ~]$ ssh -i "XXX.pem" ec2-user@52.111.111.111

1. nginx情報確認

[ec2-user@ip-172-31-4-XXX ~]$ yum info nginx

2. nginxインストール

[ec2-user@ip-172-31-4-XXX ~]$ sudo yum install nginx -y

3. インストール確認

[ec2-user@ip-172-31-4-XXX ~]$ which nginx
/usr/sbin/nginx

4. nginx稼働

[ec2-user@ip-172-31-4-XXX ~]$ sudo service nginx start
Starting nginx:                                            [  OK  ]

[ec2-user@ip-172-31-4-XXX ~]$ ps -ef | grep nginx
root      1563     1  0 09:06 ?        00:00:00 nginx: master process nginx
nginx     1564  1563  0 09:06 ?        00:00:00 nginx: worker process
ec2-user   1566  1385  0 09:06 pts/0    00:00:00 grep nginx

5. ブラウザへのアクセスを確認する

ブラウザで http://52.111.111.111 へアクセス。
以下のような画面が表示されれば OK 。

6. サービスの自動稼働に設定しておく

[ec2-user@ip-172-31-4-XXX ~]$ sudo chkconfig nginx on

7. nginxのログディレクトリへのアクセス確認

[ec2-user@ip-172-31-4-XXX ~]$ tail -f /var/log/nginx/access.log
tail: `/var/log/nginx/access.log' を 読み込み用に開くことが出来ません: 許可がありません
[ec2-user@ip-172-31-4-XXX ~]$ ls -ald /var/log/nginx
drwx------ 2 nginx nginx 4096  9月 20 08:26 /var/log/nginx

8. ログディレクトリへのアクセス権限を変更

[ec2-user@ip-172-31-4-XXX ~]$ sudo chmod 755 /var/log/nginx/
[ec2-user@ip-172-31-4-XXX ~]$ ls -ald /var/log/nginx
drwxr-xr-x 2 nginx nginx 4096  9月 20 08:26 /var/log/nginx
[ec2-user@ip-172-31-4-XXX ~]$ tail -f /var/log/nginx/access.log
XXX.XXX.XX.XXX - - [20/Sep/2015:08:29:09 +0000] ...
XXX.XXX.XX.XXX - - [20/Sep/2015:08:30:01 +0000] ...

php-fpmインストール

1. php5.6及びphp-fpmインストール

[ec2-user@ip-172-31-4-XXX ~]$ sudo yum install php56 php56-fpm -y

2. 確認用のphpファイル作成

/usr/share/nginx/html/phpinfo.php
<?php
    phpinfo();

3. php-fpmの設定変更

userとgroupをapacheからnginxに変更
/etc/php-fpm-5.6.d/www.conf
- user = apache
+ user = nginx

- group = apache
+ group = nginx

4. nginxの設定変更

/etc/nginx/nginx.conf
  http {
-   index index.html index.htm;
+   index index.php index.html index.htm;
      server {
       root /usr/share/nginx/html;

-       #location ~ \.php$ {
-       #    root           html;
-       #    fastcgi_pass   127.0.0.1:9000;
-       #    fastcgi_index  index.php;
-       #    fastcgi_param  SCRIPT_FILENAME/scripts$fastcgi_script_name;
-       #    include        fastcgi_params;
-       #}
+       location ~ \.php$ {
+       root           html;
+       fastcgi_pass   127.0.0.1:9000;
+       fastcgi_index  index.php;
+       fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
+       include        fastcgi_params;
+     }

5. php-fpm稼働及び自動稼働設定

[ec2-user@ip-172-31-4-XXX ~]$ sudo service php-fpm start
[ec2-user@ip-172-31-4-XXX ~]$ sudo chkconfig php-fpm on

6. nginx再起動

[ec2-user@ip-172-31-4-XXX ~]$ sudo service nginx restart

7. 設定変更の確認

[ec2-user@ip-172-31-4-XXX ~]$ curl -s http://localhost/phpinfo.php |grep "PHP Version"
<tr><td class="e">PHP Version </td><td class="v">5.6.8 </td></tr>

8. nginxとphp-fpmの接続をsocketにする

php-fpmの設定変更

/etc/php-fpm-5.6.d/www.conf
-   listen = 127.0.0.1:9000
+   listen =  /var/run/php-fpm/php-fpm.sock

-   ;listen.owner = nobody
-   ;listen.group = nobody
+   listen.owner = nginx  
+   listen.group = nginx

nginxの設定変更

/etc/nginx/nginx.conf
-   fastcgi_pass   127.0.0.1:9000;
+   fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;

サービス再起動

[ec2-user@ip-172-31-4-XXX ~]$ sudo service php-fpm restart
[ec2-user@ip-172-31-4-XXX ~]$ sudo service nginx restart 

php実行に問題ないか確認

[ec2-user@ip-172-31-4-XXX ~]$ curl -s http://localhost/phpinfo.php |grep "PHP Version"

バーチャル環境作成(feature1-develop.com)

1. php-fpmを設定

/etc/php-fpm-5.6.d/php-fpm-feature1-develop.conf
[feature1-develop]
user = nginx
group = nginx
listen = /var/run/php-fpm/php-fpm-feature1-develop.sock
listen.owner = nginx
listen.group = nginx
php_admin_value[disable_functions] = exec,passthru,shell_exec,system
php_admin_flag[allow_url_fopen] = off
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

2. nginxのvirtual.conf設定

/etc/nginx/conf.d/virtual.conf
server {
    listen        80;
    server_name   feature1-develop.com;
    access_log    /var/log/nginx/feature1-develop.access.log main;
    error_log    /var/log/nginx/feature1-develop.error.log;
    root /var/www/feature1;
    index index.php;
    location ~ \.php$ {
        root           /var/www/feature1;
        fastcgi_pass   unix:/var/run/php-fpm/php-fpm-feature1-develop.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

3. ドキュメントルートディレクトリ作成

[ec2-user@ip-172-31-4-XXX ~]$ sudo mkdir -p /var/www/feature1

4. index.phpファイル作成

/var/www/feature1/index.php
<?php
    phpinfo();

5. php-fpmとnginx再起動

[ec2-user@ip-172-31-4-XXX ~]$ sudo service php-fpm restart
[ec2-user@ip-172-31-4-XXX ~]$ sudo service nginx restart

6. sockファイル追加確認

[ec2-user@ip-172-31-4-XXX ~]$ ls -al /var/run/php-fpm/php-fpm-feature1-develop.sock
srw-rw---- 1 nginx nginx 0  9月 20 08:54 /var/run/php-fpm/php-fpm-feature1-develop.sock

7. 自分のパソコンにバーチャルホストへのアクセス設定

[hoge@local ~]$ sudo -- sh -c "echo 52.111.111.111 feature1-develop.com >> /etc/hosts"

8. アクセス確認

shell上で確認

# アクセス確認
[hoge@local ~]$ curl -s http://feature1-develop.com/phpinfo.php | grep "PHP Version"
<tr><td class="e">PHP Version </td><td class="v">5.6.12 </td></tr>

# 「DOCUMENT_ROOT」確認
[hoge@local ~]$ curl -s http://feature1-develop.com/phpinfo.php | grep "DOCUMENT_ROOT"
<tr><td class="e">_SERVER["DOCUMENT_ROOT"]</td><td class="v">/var/www/feature1</td></tr>

ブラウザ上で確認

http://feature1-develop.com/phpinfo.php
「DOCUMENT_ROOT」が「/var/www/feature1」になっているか確認
