After the above software is ready, we will start to install it!
Note: I didn't download the Openmeetings client here, because I couldn't find the specific client on the official website. I tried a few and didn't implement it. Finally, I modified the server, however, the final client and server are the same. If you know this, please contact me. Thank you!

First, plan the installation path of the system, where all software is stored/root/soft, and where openmeetings is installed/openmeetings,/openmeetings/red5,/openmeetings/jdk,/openmeetings/lps
Apache-ant-1.8.0-bin.tar.gz OOo_3.2.0_LinuxIntel_install_zh-CN.tar.gz
Openlaszlo-4.7.1-unix.tar.gz openmeetings_20.20.r3087.zip
Ffmpeg-0.5.1.tar.bz2 ghostscript-8.70.tar.bz2
Flash-plugin-10.0.45.2-release.i386.rpm swftools-0.9.0.tar.gz
ImageMagick-6.6.0-4.tar.bz2 jdk-6u18-linux-i586.bin
The above can be installed using yum or apt-get. If you cannot find them in the source code, you can install them using the source code.
The following two sources are provided:
1. CentOS
Download this file and then install, http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.i386.rpm
2. debian

You can choose to install YUM and APT-GET based on your own system, which will save a lot of time. You also need to emphasize that you must install the desktop environment, otherwise, your OpenOffice.org cannot be installed.

Okay. Start the installation (take CentOS5.3 as an example)
1. Install the YUM source and the desktop environment
Wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.i386.rpm
Rpm-ivh rpmforge-release-0.5.1-1.el5.rf.i386.rpm
Yum clean all
Yum groupinstall "GNOME Desktop Environment" # because I have not installed the Desktop, I need to install the Desktop first

2. Install all required software
Yum install-y mysql-server java-1.6.0-openjdk java-1.6.0-openjdk-devel ghostscript swftools ffmpeg unzip subversion sox release-core Plugin-base openoffice.org-calc openoffice.org-draw openoffice.org-impress openoffice.org-math Plugin-writer openoffice.org-graphicfilter plugin -headless

3. Set Environment Variables
Vi/etc/profile
Add the following content after the file:
// JAVA
JAVA_HOME =/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/
PATH = $ PATH: $ JAVA_HOME/bin
CLASSPATH = $ JAVA_HOME/bin/tools. jar: $ JAVA_HOME/lib/dt. jar
Export path classpath JAVA_HOME
// If ant-apache is installed, add the following two lines according to your own situation, or write them together with JAVA.
Export ANT_HOME =/usr/local/ant
Export PATH = $ PATH:/usr/local/ant/bin
Run source/etc/profile to make the configuration take effect.

4. Set the MYSQL password
If you are using a debian system, you will be prompted to enter the MYSQL password during installation.
We use CentOS, so we need to set the MYSQL password.
Chkconfig mysqld on
Service mysqld start
/Usr/bin/mysqladmin-uroot password 123456

Note: When we use Chinese, we will find that the logon interface is error. Here we will solve this problem.
Chinese garbled problem solution (1, 2)
Method 1: Create your own database and set it to UTF8 Encoding
Mysql> create database 'openobjects' default character set utf8 COLLATE utf8_general_ci;
Method 2: add content to the mysql configuration file
Vim/etc/my. cnf
Add the following content at the corresponding location
[Mysqld]
Default-character-set = utf8
Character-set-server = utf8
[Client]
Default-character-set = utf8
This solves the Chinese Garbled text problem.
