Linux

If you get the following error while installing BridgeGate on Linux you need to install the net-tools. This includes the ifconfig.  The BridgeGate install script uses ifconfig to get IP information.

Example Error Message:

What is the alias of this server? [localhost.localdomain] Can’t exec “ifconfig”: No such file or directory at /bridgegate/bin/bg_config.pl line 344, <STDIN> line 15. Use of uninitialized value in pattern match (m//) at /bridgegate/bin/bg_config.pl line 344, <STDIN> line 15.

# sudo yum install net-tools

If you encounter a (Too many open files) Exception in the /bridgegate/logs/server.log log file on a Linux system your system administrator will need to increase the number of OS File Descriptors the bridgegate process is allowed to use.

1.  To increase edit /etc/sysctl.conf add the below line, save and exit

   fs.file-max = 100000

2. We also need to increase hard and soft limits Edit /etc/security/limits.conf add the below lines before the #End, save and exit

   * soft nofile 65535
   * hard nofile 65535

3. Edit the bridgegate service, vi/etc/systemd/system/bridgegate.service  and add the below  line at the of the [Service] section, save and exit

   LimitNOFILE=65535

4. Reload systemctl to apply new setting

   sudo systemctl daemon-reload

5. Restart the bridgegate service

   sudo systemctl restart bridgegate

6. Check the file limits of the bridgegate process. First find the process id for the bridgegate process

   ps -ef | grep java
   The output will look like the following. The process id is the first number after the bgate

   Next view the limits for that process id

   cat /proc/27919/limits
