LoadModule weblogic_module */lib/mod_wl_24.so

Question

我对Apache/2.4.17 (Unix)和weblogic module (plugin) mod_wl_24.so有问题。

对于这个项目，我使用了extra目录下的httpd_vhosts.conf配置(我以前在httpd.conf中启用了这个目录，"Include conf/extra/httpd-vhosts.conf")，并且我在httpd.conf中保留了默认配置

我使用的是arch-linux，但我认为这并不重要……

我下载了正确版本的WL插件，并将WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0目录放在apache的ServerRoot下：

/etc/httpd

    drwxr-xr-x   4 root root  4096  4 dic 18.24 .
    drwxr-xr-x 100 root root 12288  9 dic 09.57 ..
    drwxr-xr-x   5 root root  4096  9 dic 11.02 conf
    lrwxrwxrwx   1 root root    22 11 nov 17.33 modules -> /usr/lib/httpd/modules
    drwxr-xr-x   5 root root  4096  4 dic 12.48 WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0

当我在apache的extra目录中配置httpd_vhosts.conf来加载插件时：

LoadModule weblogic_module WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0/lib/mod_wl_24.so

在重新启动apache后，我收到以下错误：

systemctl status httpd -l

我已经正确地为mod_wl_24.so的lib目录设置了系统上的LD_LIBRARY_PATH：

LD_LIBRARY_PATH=/etc/httpd/WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0/lib

ldd WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0/lib/mod_wl_24.so

因此，从系统的角度对libopmnsecure.so库进行了定义和阐述。

我有点绝望，因为我找不到合理的解释...

以前有没有人遇到过这样的问题？任何小小的帮助都会感激不尽:)

Answer 1

我在Red RHEL7和Apache2.4上也有类似的问题。

对于这种错误

Cannot load .../lib/mod_wl_24.so into server: libonssys.so: cannot open shared object file: No such file or directory

Library libonssys.so is given with weblogic httpd module.

在……下面

/etc/ld.so.conf.d/

创建一个值为pathToWeblogicPlugin/ pluginWeblogic.conf的文件lib

对于本示例值文件pluginWeblogic.conf，使用

/etc/httpd/WLSPlugin12.2.1-Apache2.2-Apache2.4-Linux_x86_64-12.2.1.0.0/lib

在shell运行时：

ldconfig

然后重新启动apache：

  systemctl restart httpd

Answer 2

查看以下文件：

cat /usr/lib/systemd/system/httpd.service

在服务下，它指定EnvironmentFile=/etc/sysconfig/httpd

使用Weblogic插件的LD_LIBRARY_PATH更新文件/etc/sysconfig/httpd

vi /etc/sysconfig/httpd
# Update to include Weblogic Plugin 
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/PATH/weblogic-plugins/lib
#

重新启动Apache

systemctl stop httpd.service  ; 
systemctl start httpd.service ; 
systemctl status httpd.service

Answer 3

我找到了问题所在，

当我使用"systemctl restart httpd“命令时，新的系统控制"systemd”不会加载ENV LD_LIBRARY_PATH ...我不知道为什么，但很明显，因为如果我用"apachectl restart“重启apache，mod_weblogic就会正确加载

我希望这篇文章能帮助任何有这个问题的人。
