====== CentOS6 に PHP 5.1.6 をインストールする ======
以下の内容は、CentOS 6.3 に PHP 5.3.18 (Remiリポジトリ) と MySQL 5.5.28 (Remiリポジトリ) がインストールされた環境に、PHP 5.1.6 を混在させる方法です。\\
\\

===== PHP の古いバージョンを探す =====
　古いバージョンは[[http://php.net/releases/index.php|Unsupported Historical Releases]]より探すことができる。\\

===== 少し古い OpenSSL をソースからインストール =====
CentOS 6.3 の OpenSSL が 1.0.0 なので、[[https://bugs.php.net/bug.php?id=53547|Bug #53547 Cannot compile PHP with OpenSSL]] のバグで PHP をビルドできないようである。\\
<code>
$ rpm -qa | grep openssl
openssl-1.0.0-25.el6_3.1.x86_64
openssl-devel-1.0.0-25.el6_3.1.x86_64
</code>
バグを回避する為に、少し古い OpenSSL をソースからインストールする。\\
  - OpenSSL 0.9.8 のソースをダウンロードする。<code>
$ cd ~/work
$ curl -O http://www.openssl.org/source/openssl-0.9.8x.tar.gz
</code>※openssl-0.9.8e.tar.gz だと x86_64 でバグでビルドできない。\\ [[http://rt.openssl.org/Ticket/Display.html?id=2094&user=guest&pass=guest|#2094: BUG: 0.9.8x md5-x86_64.s:41: Error: 0xd76aa478 out range of signed 32bit displacement]]
  - ダウンロードした圧縮ファイルを解凍する。<code>
$ tar zxvf openssl-0.9.8x.tar.gz
</code>
  - configure する。(openssl は ./config)<code>
$ cd openssl-0.9.8x
$ ./config --prefix=/usr/local shared
</code>
  - ビルドしてインストールする。<code>
$ make
$ sudo make install LIBDIR=lib64
</code>※本家の tar ball は x86_64 でも /usr/local/lib にインストールされるので、/usr/local/lib64に配置するように LIBDIR=lib64 を指定する。
===== PHP をソースからインストール =====
  - ソースをダウンロードする。<code>
$ cd work
$ curl -O http://museum.php.net/php5/php-5.1.6.tar.bz2
</code>
  - ダウンロードした圧縮ファイルを解凍する。<code>
$ tar jxvf php-5.1.6.tar.bz2
</code>
  - ビルドに必要なパッケージをインストールする。<code>
$ sudo yum install zlib-devel openssl-devel db4-devel pcre-devel
$ sudo yum install libicu libicu-devel gettext-devel gd-devel
$ sudo yum install readline-devel libxml2-devel libxslt-devel
$ sudo yum install libcurl-devel
$ sudo yum install mysql-devel postgresql-devel --enablerepo=remi
</code>
  - configure する。<code>
$ cd php-5.1.6
$ ./configure \
--prefix=/usr/local/lib64/php-5.1.6 \
--with-config-file-path=/usr/local/lib64/php-5.1.6 \

--with-xsl=shared \
--enable-force-cgi-redirect \

--enable-sqlite-utf8 \
--enable-zend-multibyte \
--program-suffix=51 \
2>&1 | tee configure_log.txt
</code>※configure のオプション一覧は ./configure --help で確認できる。
  - curl の interface.c がエラーになるので修正する。\\ 以下の2つの行をコメントアウトする。\\ REGISTER_CURL_CONSTANT(CURLOPT_FTPASCII); \\ REGISTER_CURL_CONSTANT(CURLOPT_PASSWDFUNCTION);<code>
$ cp ext/curl/interface.c ext/curl/interface.c.org
$ vi ext/curl/interface.c
$ diff ext/curl/interface.c ext/curl/interface.c.org
274c274
<       //REGISTER_CURL_CONSTANT(CURLOPT_FTPASCII);
---
>       REGISTER_CURL_CONSTANT(CURLOPT_FTPASCII);
314c314
<       //REGISTER_CURL_CONSTANT(CURLOPT_PASSWDFUNCTION);
---
>       REGISTER_CURL_CONSTANT(CURLOPT_PASSWDFUNCTION);
</code>
  - mysqli の mysqli.c がエラーになるので、mysql.h を修正する。<code c>
enum mysql_protocol_type
{
MYSQL_PROTOCOL_DEFAULT, MYSQL_PROTOCOL_TCP, MYSQL_PROTOCOL_SOCKET,
MYSQL_PROTOCOL_PIPE, MYSQL_PROTOCOL_MEMORY
};
</code> と <code c>
typedef struct character_set
{
unsigned int number; /* character set number */
unsigned int state; /* character set state */
const char *csname; /* collation name */
const char *name; /* character set name */
</code> の間に <code c>
/*
  There are three types of queries - the ones that have to go to
  the master, the ones that go to a slave, and the adminstrative
  type which must happen on the pivot connectioin
*/
enum mysql_rpl_type
{
  MYSQL_RPL_MASTER, MYSQL_RPL_SLAVE, MYSQL_RPL_ADMIN
};
</code> を挿入する。<code>
$ sudo cp /usr/include/mysql/mysql.h /usr/include/mysql/mysql.h.org
$ sudo vi /usr/include/mysql/mysql.h
$ diff /usr/include/mysql/mysql.h /usr/include/mysql/mysql.h.org
227,236d226
< /*
<   There are three types of queries - the ones that have to go to
<   the master, the ones that go to a slave, and the adminstrative
<   type which must happen on the pivot connectioin
< */
< enum mysql_rpl_type
< {
<   MYSQL_RPL_MASTER, MYSQL_RPL_SLAVE, MYSQL_RPL_ADMIN
< };
<
</code>
  - mysqli の mysqli_api.c がエラーになるので修正する。\\ 145行目以降4カ所: <code c>
bind[ofs].buffer = (gptr)&Z_DVAL_PP(args[i]);
</code><code c>
bind[ofs].buffer = &Z_DVAL_PP(args[i]);
</code>※(gptr)にキャストしている部分をすべて除去する。<code>
$ cp ext/mysqli/mysqli_api.c ext/mysqli/mysqli_api.c.org
$ vi ext/mysqli/mysqli_api.c
$ diff ext/mysqli/mysqli_api.c ext/mysqli/mysqli_api.c.org
145c145
<                               bind[ofs].buffer = &Z_DVAL_PP(args[i]);
---
>                               bind[ofs].buffer = (gptr)&Z_DVAL_PP(args[i]);
151c151
<                               bind[ofs].buffer = &Z_LVAL_PP(args[i]);
---
>                               bind[ofs].buffer = (gptr)&Z_LVAL_PP(args[i]);
601c601
<                                               stmt->stmt->params[i].buffer = &Z_LVAL_PP(&stmt->param.vars[i]);
---
>                                               stmt->stmt->params[i].buffer = (gptr)&Z_LVAL_PP(&stmt->param.vars[i]);
605c605
<                                               stmt->stmt->params[i].buffer = &Z_LVAL_PP(&stmt->param.vars[i]);
---
>                                               stmt->stmt->params[i].buffer = (gptr)&Z_LVAL_PP(&stmt->param.vars[i]);
</code>
  - ビルドしてインストールする。<code>
$ make
$ sudo make install
</code>

===== ビルドした PHP をテストする =====
<code>
$ cp php.ini-dist php.ini
$ vi php.ini
</code>
php.ini に extension をロードするように追記する。
<code ini>
extension=modules/pcre.so
</code>
テストを実行する。
<code>
$ make test

You may have found a problem in PHP.
We would like to send this report automatically to the
PHP QA team, to give us a better understanding of how
the test cases are doing. If you don't want to send it
immediately, you can choose "s" to save the report to
a file that you can send us later.
Do you want to send this report now? [Yns]: s
