PHP安装 OCI8 和 PDO_OCI 扩展和PDO、swoole连接池配置示例

PHP安装 OCI8 和 PDO_OCI 扩展和PDO、swoole连接池配置示例

本文环境：服务器（centos7.9）PHP版本（7.2.33）

安装Oracle客户端

• 下载 Oracle Instantclient ，包括2个文件：Basic、SDK 。下载你机器对应的版本

https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html

instantclient-basic-linux.x64-21.6.0.1.0.zip
instantclient-sdk-linux.x64-21.6.0.1.0.zip

• 配置解压 Oracle Instantcient ，并创建必要的软连接（注意你下载的文件的版本，可能与文章的不同）

mkdir -p /opt/oracle
mv ./instantclient-*.zip /opt/oracle/
cd /opt/oracle
unzip instantclient-basic-linux.x64-21.6.0.1.0.zip
unzip instantclient-sdk-linux.x64-21.6.0.1.0.zip

mv instantclient_21.6 instantclient
cd instantclient
ln -s /opt/oracle/instantclient/libclntsh.so.21.1 /opt/oracle/instantclient/libclntsh.so
ln -s /opt/oracle/instantclient/libocci.so.21.1 /opt/oracle/instantclient/libocci.so
ln -s /opt/oracle/instantclient/ /opt/oracle/instantclient/lib

mkdir -p include/oracle/21.6/
cd include/oracle/21.6/
ln -s ../../../sdk/include client
cd -

mkdir -p lib/oracle/21.6/client
cd lib/oracle/21.6/client
ln -s ../../../ lib
cd -

mkdir -p /opt/oracle/instantclient/lib/oracle/21.6
ln -s /opt/oracle/instantclient/sdk  /opt/oracle/instantclient/lib/oracle/21.6/client
ln -s /opt/oracle/instantclient  /opt/oracle/instantclient/lib/oracle/21.6/client/lib

echo /opt/oracle/instantclient/ | sudo tee -a /etc/ld.so.conf.d/oracle.conf
ldconfig

安装 oci8 和 pdo_oci 扩展

• 扩展包从php对应版本的源码包下ext下获取，记得切换到对应的版本分支,我的php版本为7.2.33

https://github.com/php/php-src/tree/PHP-7.2.33

• 安装oci8

  cd oci8
  phpize
  ./configure --with-oci8=instantclient,/opt/oracle/instantclient/ --with-php-config=/www/server/php/72/bin/php-config
  make
  make install
  

• 安装pdo_oci

  cd pdo_oci
  phpize
  ./configure --with-pdo-oci=instantclient,/opt/oracle/instantclient,21.6 --with-php-config=/www/server/php/72/bin/php-config
  make
  make install
  

• 打开phpini,在文本尾部添加，重启就OK了

  [oci8]
  extension = oci8.so
  [pdo_oci]
  extension = pdo_oci.so

使用PDO连接Oracle

• PDO连接

  语法

  $dsn = "oci:dbname=//IP地址:端口(默认1521)/数据库名";

  new PDO(user, $pwd);

  $dsn="oci:dbname=//127.0.0.1:1521/user'";
  $user="root";
  $pwd="123456"
  $pdo = new PDO($dsn, $user, $pwd);
  

• 使用swoole连接池，前提安装swoole扩展

  $PDOConfig = (new PDOConfig)
                  ->withDriver('oci')
                  ->withDbname('//127.0.0.1:1521/user')
                  ->withCharset('utf8')
                  ->withUsername('root')
                  ->withPassword('123456');
  // 初始化连接池
  $pool = new PDOPool($PDOConfig);
