centos7添加php7 oracel扩展

一、安装Oracle Client

yum -y install gcc

下载instantclient

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

这里我选择的12.2

开始安装，执行命令

rpm -ivh oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm  
rpm -ivh oracle-instantclient12.2-devel-12.2.0.1.0-1.x86_64.rpm  
rpm -ivh oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm  
echo '/usr/lib/oracle/12.2/client64/lib/' > /etc/ld.so.conf.d/oracle-x86_64.conf #配置Oracle搜索加载动态库
ldconfig
ln -s /usr/lib/oracle/12.2/client64 /usr/lib/oracle/12.2/client  
ln -s /usr/include/oracle/12.2/client64 /usr/include/oracle/12.2/client
mkdir -p /usr/lib/oracle/12.2/network/admin

二、设定Oracle Client

echo 'export ORACLE_HOME=/usr/lib/oracle/12.2/client64/' >> /etc/profile
echo 'export LD_LIBRARY_PATH=/usr/lib/oracle/12.2/client64:$LD_LIBRARY_PATH' >> /etc/profile  
echo 'export NLS_LANG="AMERICAN_AMERICA.AL32UTF8"' >> /etc/profile 
echo 'export PATH=$PATH:$ORACLE_HOME/bin' >> /etc/profile 
echo 'export TNS_ADMIN=/usr/lib/oracle/12.2/network/admin' >> /etc/profile 
source /etc/profile 

三、php安装oci8扩展

3.2 编译安装

wget https://pecl.php.net/get/oci8-2.2.0.tgz
tar zxvf oci8-2.2.0.tgz
cd oci8-2.2.0

phpize  
./configure --with-php-config=php-config --with-oci8=shared,instantclient,/usr/lib/oracle/12.2/client/lib  
make && make install  
cd ..
ll /usr/lib64/php/modules  
echo 'extension=oci8.so' > /etc/php.d/oci8.ini

3.2 pecl 安装

pecl install oci8

期间会出现

Please provide the path to the ORACLE_HOME directory. Use 'instantclient,/path/to/instant/client/lib' if you're compiling with Oracle Instant Client [autodetect] :

输入：

shared,instantclient,/usr/lib/oracle/12.2/client64/lib

回车

注意后面连接可能会因为oracle源的版本不同而不同

四、手动添加oci8扩展

举例：

touch /etc/php.d/oci8.ini
echo 'extension = oci8.so' > /etc/php.d/oci8.ini

查看结果

php -m | grep oci8

五、重置fpm或web服务

错误处理

错误1：/tmp/oci8/php_oci8_int.h:46:29: fatal error: oci8_dtrace_gen.h: No such file or directory

解决：

如果需要 DTRACE:

yum install systemtap-sdt-devel
export PHP_DTRACE=yes

如果不需要 DTRACE:

    modify the file 'php_oci8_int.h', change the 48th line 

    #include "oci8_dtrace_gen.h" to #undef HAVE_OCI8_DTRACE

如果还有错你不妨换一个版本试试。。。
