Linux下安装oracle客户端并配置php5.3_PHP

linux oracle Install client Configuration

因项目需要在linux下进行php5.3的oracle客户端编译,简要介绍一下步骤及走过的弯路。

1.下载Oracle客户端程序包,其中包含OCI、OCCI和JDBC-OCI等相关文件。

1.1下载文件地址

http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
根据操作系统的版本选择对应的软件,我需要的是X86_64选择
Instant Client for Linux x86-64

1.2需要下载的文件如下:

代码如下:


oracle-instantclient11.1-basic-11.1.0.7.0-1.x86_64.rpm
oracle-instantclient11.1-devel-11.1.0.7.0-1.x86_64.rpm
oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.x86_64.rpm

需要强调的一点是这里需要注册一个oracle的账户才能正常下载。

2.安装Oracle客户端程序包。

将程序包上传到服务器指定目录里

代码如下:


chmod +x *.rpm
#给RPM包赋执行权限
rpm -ivh oracle-instantclient11.1-basic-11.1.0.7.0-1.x86_64.rpm oracle-instantclient11.1-devel-11.1.0.7.0-1.x86_64.rpm oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.x86_64.rpm
#安装RPM包
echo "/usr/lib/oracle/11.1/client64/lib/" > /etc/ld.so.conf.d/oracle_client.conf
#将库路径加到默认加载中
/sbin/ldconfig
#重新加载动态链接库

3.安装OCI8的php扩展(这里指定php的安装路径为/usr/local/webserver/php)

代码如下:


yum install libaio
#yum安装libaio库,libaio是Linux下的一个异步非阻塞接口,它提供了以异步非阻塞方式来读写文件的方式,读写效率比较高
wget http://pecl.php.net/get/oci8-1.4.10.tgz
#下载OCI扩展
tar zxvf oci8-1.4.10.tgz
#解压
cd oci8-1.4.10
/usr/local/webserver/php/bin/phpize CFLAGS="-I/usr/lib/oracle/11.1/client64" CXXFLAGS="-I/usr/lib/oracle/11.1/client64"
#使用phpize准备 PHP 外挂模块的编译环境,会根据指定的环境变量生成编译时需要的makefile,phpize是属于php-devel的内容,所以centos下只要运行yum install php-devel进行安装即可
./configure –with-php-config=/usr/local/webserver/php/bin/php-config –with-oci8=/usr/lib/oracle/11.1/client64
make
make install
#编译,安装

需要强调的是make的时候会报错,显示各种找不到库文件,需要对makefile文件进行修改加入oralce的运行库地址
打开makefile,寻找INCLUDE,形式如下:
INCLUDES = -I/usr/local/php/include/php -I/usr/include/oracle/10.2.0.3/client
然后在末尾加上="-I/usr/lib/oracle/11.1/client64,然后重新make就会成功了。

4.修改PHP.ini(/usr/local/webserver/php/etc/php.ini)

在extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"后增加一行:

代码如下:


extension = "oci8.so"

5.重启apache让OCI生效

6.在web目录下创建phpinfo.php文件在其中输入一下内容,并通过web访问

代码如下:


phpinfo();
?>

如果找到OCI8的部分就说明OCI安装正常了,如下图所示

接下来就能通过php访问oracle数据库了,需要注意的是php下Oracle的连接字符串

代码如下:


$username='***';
$passwd='***';
$protocol='TCP';
$SERVICE_NAME='***';
$ORACLE_SERVER_IP_ADDRESS='***.***.***.***';
$Port='1521′;
$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = $protocol)(HOST = $ORACLE_SERVER_IP_ADDRESS)(PORT = $Port)))(CONNECT_DATA=(SID=$SERVICE_NAME)))";
$conn = oci_connect($username,$passwd, $db);
PutEnv("NLS_LANG=SIMPLIFIED CHINESE_CHINA.AL32UTF8");
if (!$conn) {
    $e = oci_error();
    print htmlentities($e['message']);
    exit;
}else {
    echo "连接oracle成功!";
    return $conn;
}
?>

MongoDB vs. Oracle: Choosing the Right Database for Your Needs MongoDB vs. Oracle: Choosing the Right Database for Your Needs Apr 22, 2025 am 12:10 AM

MongoDB is suitable for unstructured data and high scalability requirements, while Oracle is suitable for scenarios that require strict data consistency. 1.MongoDB flexibly stores data in different structures, suitable for social media and the Internet of Things. 2. Oracle structured data model ensures data integrity and is suitable for financial transactions. 3.MongoDB scales horizontally through shards, and Oracle scales vertically through RAC. 4.MongoDB has low maintenance costs, while Oracle has high maintenance costs but is fully supported.
