CentOS7.1にPHP5.2.17環境を構築する

Last updated at Posted at 2017-04-28

今さら感あるが、どうしても必要になったので構築した。
CentOS7.1ならではの手順は無かった。

事前準備

タイムゾーンを変更する

$ sudo timedatectl 
      Local time: Tue 2017-05-09 04:19:11 UTC
  Universal time: Tue 2017-05-09 04:19:11 UTC
        RTC time: Tue 2017-05-09 04:19:11
       Time zone: UTC (UTC, +0000)
     NTP enabled: n/a
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a

タイムゾーンを Asia/Tokyo に変更する

$ sudo timedatectl set-timezone Asia/Tokyo

設定確認

$ sudo timedatectl 
      Local time: Tue 2017-05-09 13:19:19 JST
  Universal time: Tue 2017-05-09 04:19:19 UTC
        RTC time: Tue 2017-05-09 04:19:19
       Time zone: Asia/Tokyo (JST, +0900)
     NTP enabled: n/a
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a

ミドルウェアインストール

ソースを取得するためのミドルウェアをインストールする

$ sudo yum -y install wget

ソースコンパイルに必要なミドルウェアをインストールする

$ sudo yum -y install gcc make libxml2 libxml2-devel

Apacheをインストールする

$ sudo yum -y httpd httpd-devel

httpd-devel は --with-apxs2=/usr/bin/apxs で 必要な apxs がインストールされる
Apache入れたのにapxsが無い場合は疑うと良い

PHPインストール

PHPのソースを取得する

$ cd /usr/local/src
$ wget https://museum.php.net/php5/php-5.2.17.tar.gz
$ tar zxvf php-5.2.17.tar.gz

Patch

ext/dom/node.c

以下のエラーが発生する。

unixd_config

以下のエラーが発生する。

Apache2.4起動時にlibphp5.soの読み込みに失敗する。

要因は以下
http://httpd.apache.org/docs/current/developer/new_api_2_4.html

unixd_configをap_unixd_configに変更する。

configure

$ ./configure --with-apxs2=/usr/bin/apxs --enable-mbstring --enable-mbregex

他、環境に合わせて変更すれば良い

make

$ sudo make ZEND_EXTRA_LIBS='-liconv'
$ sudo make
$ sudo make install

権限

$ chown -R apache:apache /var/www/mcd/rsync
$ find /var/www/mcd/rsync -type d -exec chmod 770 {} ;
$ find /var/www/mcd/rsync -type f -exec chmod 660 {} ;

おまけ：ビルド条件の確認

configure にて、ビルド条件を確認する。
