OCS Inventory 安裝記錄 CentOS 7

BUBU 之前公司有在使用資管理系統，結果因為市面上的資管理系統費用過高，外加功能太多總覺都使用不到，所以只要去尋找開源的軟體來使用，剛好尋找到這一個 OCS Inventory 開源軟體，這還是要搭配另一個開源軟體來一起使用我先記錄 OCS 服務另一套等我測試過再來記錄，目前之前的公司及現任公司都有在使用這一套資產管理功能雖然沒有市面上功能來的多，但最起碼基本的功能都達到目前的需求。

運行環境

本工作室環境都是在 「Proxmox VE 」 虛擬系統上架設，都是以 「 LXC 」模式為主，除非有特殊狀況會告知使用 「 VM 」 模式

  • 系統環境： CentOS 7
  • Web 服務： Apache 2.4.39
  • PHP 服務： PHP 7.3
  • 資料庫服務： MariaDB 10.3

由於 OCS Inventory 只能在 Apache 服務上運行不能在 Nginx ，由於有些服務在 Nginx 上是無法運行只能在 Apache 上才能運行。

安裝 Apache 服務

由於在本知識庫已經有教學怎麼安裝服務了，請參考本篇的安裝方式 Apache支援 TLS1.3

安裝 MariaDB 服務

  • 首先新增加 MariaDB.repo 官方載點
新增加MariaDB安裝檔
vim /etc/yum.repos.d/MariaDB.repo

再填入內容為以下

# MariaDB 10.3 CentOS repository list - created 2018-08-20 14:44 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

增加完畢後在下命令安裝

yum install MariaDB-server MariaDB-client -y
  • 資料庫安裝及設定
systemctl restart mariadb ; systemctl enable mariadb   # 啟動資料庫服

mysql_secure_installation   # 設定資料庫的root密碼

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 第一次設定，直接按 Enter 鍵即可
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] 按 Y 設定資料庫 root 密碼
New password: 輸入新密碼
Re-enter new password: 再次輸入新密碼
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] 按 Y 移除anonymous users
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] 按 Y 關閉 root 遠端登入
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] 按 Y 移除資料表 test
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] 按 Y 重新載入資料表權限
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

安裝 PHP 服務

  • 先安裝額外的套件及載點
yum install -y epel-release yum-utils
  • 因內鍵預設版本是 PHP 5.4 因此本版官方已不在維護，建議直接安裝當時官方所提供主要版本，現在安裝版本是 PHP 7.3
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
yum-config-manager --disable remi-php54
yum-config-manager --enable remi-php73
安裝 PHP 套件
yum install -y php php-mysqlnd php-pdo php-xml php-pear php-devel php-mbstring re2c gcc-c++ gcc \
php-fpm php-mysql php-gd php-cli php-json php-opcache php-curl php-ldap php-odbc php-xmlrpc php-soap \
curl curl-devel php-intl php-zip php-common php-domxml php-imap php-pear-CAS php-pecl-apcu \
php-pecl-zip
安裝好 PHP 要去修改 vim /etc/php.ini 設定檔
修改前
;cgi.fix_pathinfo=1
修改後
cgi.fix_pathinfo=0
修改時區
[Date]
修改前
;date.timezone = 
修改後
date.timezone = Asia/Taipei

; 記憶體用量上限
memory_limit = 512M

; Script執行時間上限(單位：秒)
max_execution_time = 600
; Script處理資料時間上限(單位：秒)
max_input_time = 600
; Socket無回應斷線時間(單位：秒)
default_socket_timeout = 600

存檔
:wq

安裝 Perl 套件

yum install -y perl-Archive-Zip perl-Compress-Zlib perl-DBD-MySQL perl-DBI perl-Mojolicious perl-Net-IP \
perl-Plack perl-SOAP-Lite perl-Switch perl-XML-Entities perl-XML-Simple

設定 OCS 資料庫

mysql -u root -p

create database ocsweb CHARACTER SET utf8 COLLATE utf8_unicode_ci; 
CREATE USER 'ocs'@'localhost' IDENTIFIED BY 'New-Password';
GRANT ALL PRIVILEGES ON ocsweb.* TO 'ocs'@'localhost' IDENTIFIED BY 'New-Password';
FLUSH PRIVILEGES;

安裝 OCS Inventory Server 服務

  • 由於此安裝的版本是屬於 2.4.1 版，那目前的版本是 2.6 版，可以先安裝此版本先然後再用升級的方式升到新版。

  • 下載 OCS Inventory 官方的套件來源

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
wget https://rpm.ocsinventory-ng.org/ocsinventory-release-latest.el7.ocs.noarch.rpm
用 yum 來安裝 repo
yum install -y ocsinventory-release-latest.el7.ocs.noarch.rpm epel-release-latest-7.noarch.rpm
安裝 OCS 服務
yum install ocsinventory-server

ocs-1.png

ocs-2.png

版本更新升級

  • 首先到 官方的 GitHub 查看是否有新版可以下載使用當下版本是 2.6 ，以照當時所下載新版為主。
wget https://github.com/OCSInventory-NG/OCSInventory-ocsreports/releases/download/2.6/OCSNG_UNIX_SERVER_2.6.tar.gz
  • 安裝新的版本
解壓剛剛下載的版本

tar -xvzf OCSNG_UNIX_SERVER_2.6.tar.gz

cd OCSNG_UNIX_SERVER_2.6

./setup.sh

ocs-3.png

  • 執行後只要一直照著預設值不動，只有一個地方要注意選擇性改不改的路徑

這是修改後給予的路徑
Where to copy Administration Server static files for PHP Web Console
[/usr/share/ocsinventory-reports]?/var/www/html/

只要看到 Enjoy OCS Inventory NG ;-) 表示你已安裝成功了

設定後續的設定值

  • 因版本更新有些權限可能會有異動過，所以需要手動修正回來
注意剛剛如果有修改路徑的話，後面的路徑要指向剛剛你所設定的路徑
chmod -R 766 /var/www/html/ocsreports

只給 apache 服務使用，路徑要注意如有修改記得要改
chown -R apache:apache /var/www/html/ocsreports
此路徑不用改，因為是預設
chown -R apache:apache /var/lib/ocsinventory-reports/

注意剛剛如果有修改路徑的話，後面的路徑要指向剛剛你所設定的路徑 
chcon -R -t httpd_sys_rw_content_t /var/www/html/ocsreports
備註：
httpd_sys_rw_content_t 要讓httpd寫入的目錄，例如上傳目錄

OCS Inventory 記錄無法收集原因

BUBU 在測試的時候發現無法正常收到設備回報，去查了一下 OCS Log 檔，出現這樣子的錯誤，如果出現這樣子的錯誤表示 OCS 設定檔系統沒有協助設定好，這個意思是說 「 z-ocsinventory-server.conf 」設定檔裡的密碼是錯的，導至無法寫入資料庫要，要進到此設定檔裡面做修改就好了

ocs-error-1.png

vim /etc/httpd/conf.d/z-ocsinventory-server.conf

修改
PerlSetVar OCS_DB_PWD “New-Password”
  • 畫面如下

ocs-error-2.png

  • 然後再確認一下
vim /var/www/html/ocsreports/dbconfig.inc.php

注意此的密碼是不是沒有正確寫入為資料庫的密碼
define(“PSWD_BASE”,”New-Password”);

以上都確認好之後重啟服務，這樣子就可以正常收到資料了

systemctl restart httpd ; systemctl restart mariadb
