Introduction

Overview

Tengine is a web server project initiated by Taobao. Tengine provides many advanced functions and features based on Nginx to meet the requirements of websites with large access traffic. It aims to build an efficient and secure web platform.

Programming language: C

Brief description: lightweight web server

Tengine 2.2.2

NOTE: This document applies to Tengine 2.2.2. However, you can refer to this document when porting other Tengine versions.

Operating System

ItemVersion:

Kernel4.19.90-2003.4.0.0036.oe1.aarch64

Installing the OS

For details, see openEuler 20.03 LTS SP1 Installation Guide.

Checking the Current System Information

[root@localhost ~]# cat /etc/os-release
NAME="openEuler"
VERSION="20.03 (LTS-SP1)"
ID="openEuler"
VERSION_ID="20.03"
PRETTY_NAME="openEuler 20.03 (LTS-SP1)"
ANSI_COLOR="0;31"

NOTE: When installing the OS for the first time, select "Server with GUI" instead of "Minimal Install". Otherwise, lots of software packages need to be installed manually.

Installing Tengine

Configuring the DNS Resolution File

[root@localhost ~]# echo "nameserver 114.114.114.114" >> /etc/resolv.conf

Installing Dependencies

[root@localhost ~]# yum install gcc gcc-c++ make libtool zlib zlib-devel pcre pcre-devel perl-devel perl-ExtUtils-Embed wget vim -y

Obtaining Tengine RPM from the Mirror Site

Note: The RPM packages in the mirror site are compiled and packaged using open-source code, and then uploaded to the mirror site.

Obtaining the RPM Package of Tengine 2.2.2.

[root@localhost ~]# cd /home
[root@localhost home]# wget https://mirrors.huaweicloud.com/kunpeng/yum/el/7/aarch64/Packages/web/tengine-2.2.2-1.el7_4.ngx.aarch64.rpm

Evaluating Compatibility

Downloading the Tool

wget https://repo.oepkgs.net/openEuler/rpm/openEuler-20.03-LTS-SP1/stable/contrib/x2openEuler/noarch/Packages/x2openEuler-1.0-1.noarch.rpm

User guide:
https://gitee.com/openeuler/docs/blob/stable2-20.03_LTS_SP1/docs/zh/docs/thirdparty_migration/x2openEuleruseguide.md

Deploying the Tool

rpm -ivh x2openEuler-1.0-1.noarch.rpm

NOTE: Install the RPM package as the root user. Currently, the network is required for downloading and installing dependencies. NOTE: Install dependencies such as bzip2-devel as prompted.

su x2openEuler
x2openEuler redis-db -init

Enter the following information about the Redis database in sequence. IP address: 127.0.0.1 Port: 6379 Database index (0-16): 0 Password (encrypted by the tool): If the Redis password is not set or is empty, press Enter.

x2openEuler init source_centos7.6-openEuler20.03-LTS-SP1.tar.gz

Note: After x2openEuler is installed using an RPM package, the default resource package (source_centos7.6-openEuler20.03-LTS-SP1.tar.gz) is generated in the /opt/x2openEuler directory. To support the evaluation of hardware compatibility between CentOS 8.2 and openEuler 20.03 LTS SP1, you need to obtain and import the corresponding static resource package. For example, if the resource package is source_centos8.2-openEuler20.03-LTS-SP1.tar.gz, run x2openEuler init source_centos8.2-openEuler20.03-LTS-SP1.tar.gz to import the package.

Scanning the Software

x2openEuler scan tengine-2.2.2-1.el7_4.ngx.aarch64.rpm
The x2openEuler user must have the read permission on the file to be analyzed.
After the scan is complete, an HTML report is generated in the /opt/x2openEuler/output directory.

Viewing Evaluation Results

The software compatibility evaluation report consists of three parts: dependency compatibility, C/C++ interface compatibility, and Java interface compatibility. Dependency compatibility reflects the required direct dependencies during software installation. If the dependency compatibility is not 100%, the installation fails. Interface compatibility reflects the calling of other software packages, dynamic libraries, or system interfaces during the running of the software. If the interface compatibility is not 100%, an exception may be triggered when a certain function is called. Manual confirmation is recommended for some results. The priority of software packages is as follows: packages that have been ported to openEuler > manually recompiled packages for openEuler > packages for CentOS.

Result: The report shows that the external interface compatibility is 100%. The dependency package compatibility passes the manual review. The Tengine 2.2.2 software package is compatible with the openEuler 20.03 LTS SP1.
