在最后添加如下环境变量

Golang连接Oracle 需要安装Oracle Full Client或Instant Client

#选择Instant Client for Linux x86-64下载包如下:instantclient-basic-linux.x64-21.1.0.0.0.zipinstantclient-sqlplus-linux.x64-21.1.0.0.0.zipinstantclient-sdk-linux.x64-21.1.0.0.0.zip#都解压到 instantclient_21_1 这个目录,直接解压会解压到instantclient_21_1目录unzip instantclient-basic-linux.x64-21.1.0.0.0.zipunzip instantclient-sdk-linux.x64-21.1.0.0.0.zipunzip instantclient-sqlplus-linux.x64-21.1.0.0.0.zip#打印instantclient_21_1目录的路径pwd/home/oracle/instantclient_21_1

安装pkg-config

CentOS自带了pkg-config,这里不在安装

#打印pkg-config版本pkg-config --version

创建配置文件oci8.pc

vim /home/oracle/oci8.pc oci8.pc文件内容如下:

prefix=/home/oracle/instantclient_21_1libdir=${prefix}includedir=${prefix}/sdk/include/glib_genmarshal=glib-genmarshalgobject_query=gobject-queryglib_mkenums=glib-mkenumsName: oci8Description: oci8 libraryLibs:-L${libdir}-lclntshCflags:-I${includedir}Version:21.1

配置环境变量

vim /etc/profile

在最后添加如下环境变量

# Oracle的OCI套件export LD_LIBRARY_PATH=/home/oracle/instantclient_21_1# oci8.pc文件所在路径export PKG_CONFIG_PATH=/home/oracle使配置生效source /etc/profile

运行Golang连接Oracle报错一:

# github.com/mattn/go-oci8In file included from../github.com/mattn/go-oci8/c_helpers.go:3:0:./oci8.go.h:1:17: fatal error: oci.h:No such file or directory#include^compilation terminated.

是因为配置的环境变量,oci8.pc文件所在路径不对,找不到oci8.pc文件导致的注意这个路径配置对 export PKGCONFIGPATH=/home/oracle

运行Golang连接Oracle报错二:

dyld:Librarynot loaded:@rpath/libclntsh.dylib.19.1Referencedfrom:/var/folders/_f/n3km_s7j6_9f8qzpkf9w395h0000gn/T/go-build114883360/b001/exe/oracleoci8Reason: image not found

添加软链接,解决报错

ln -s /home/oracle/instantclient_21_1/libclntsh.so.21.1/usr/lib/libclntsh.soln -s /home/oracle/instantclient_21_1/libocci.so.21.1/usr/lib/libocci.soln -s /home/oracle/instantclient_21_1/libociei.so /usr/lib/libociei.soln -s /home/oracle/instantclient_21_1/libnnz21.so /usr/lib/libnnz12.so
