6.3.1 Installing WebSphere 8.5.5 Fix Pack 20
After the installation of the IBM Security Directory Services 6.4, we can use the IBM installation manager to upgrade IBM WebSphere to IBM WebSphere 8.5.5 Fix Pack 20, following the same procedure as used in ResearchGate DOI: https://doi.org/10.13140/RG.2.2.33527.57761
(IBM Security Directory Services 6.4- Installation on RHEL 8.0) for installing IBM WebSphere 8.5.5 Fix Pack 15 which is described, with full screenshots, starting from page 53 through to page 78.
6.4 Installation of WebSphere 8.5.5.x
First, we create the installation directory on the Linux server:
[root@localhost InstallManager18]#
pwd
/opt/IBM/Installs/
[root@localhost Installs]#
mkdir WebSphere855
[root@localhost Installs]#
cd WebSphere855/
Signed in as root use the following commands to install a SFTP server:
dnf install vsftpd
Make a backup copy of the SFTP configuration file:
mv /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf_orig
Start with a clean configuration file:
grep -v ^# /etc/vsftpd/vsftpd.conf_orig > /etc/vsftpd/vsftpd.conf
View the initial configuration file and start the system:
cat /etc/vsftpd/vsftpd.conf
This should show the following:
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
listen=NO
listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
If the above file does not exist use the editor: vi /etc/vsftpd/vsftpd.conf and add the above lines. Start and enable the sftp service:
systemctl start vsftpd
systemctl enable vsftpd
Open firewall FTP port 21 incoming connections:
firewall-cmd –zone=public –permanent –add-service=ftp
firewall-cmd –reload
Test the FTP connection from the remote host using the ftp command. Use your regular user credentials to login. For example, create an FTP connection to host IP using the procedure as follows:
set the security on the /opt and subdirectories giving the wasadm group ownership:
chown root:wasadm -R /opt
Using binary mode to transfer files. Enter ftp from the windows command line (run cmd.exe to open the window):
ftp>open 192.168.50.128
Or anything the host IP or DNS Host RHEL 8.0 server name is set to. Enter the username and password, when prompted. Move to the local binary installation directory using lcd. NB use the lcd ftp command to select the local windows installation binary holding directory.
Use the ftp command, mput WASND.zip to copy the three WebSphere installation files. Now copy the ftp’d Base WebSphere 8.5.5 installation ZIP files to the WebSphere Installs subdirectory: cp /home/wasadm/WASND.zip /opt/IBM/Installs/WebSphere855/
As an alternative, to use the VMware mapped directory system use:
[root@localhost WebSphere855]# cp /mnt/hgfs/LINUX/WAS_8.5.5/WASND_v8.5.5_*.zip .
Where the mapped directory root was set as LINUX.
Note: This takes a while to complete. View the copied WebSphere installation files using:
[root@localhost WebSphere855]# ls
WASND_v8.5.5_1of3.zip WASND_v8.5.5_2of3.zip WASND_v8.5.5_3of3.zip
Then unpack the base installation using:
unzip WASND_v8.5.5_1of3.zip
unzip WASND_v8.5.5_2of3.zip
unzip WASND_v8.5.5_3of3.zip
After unpacking the three .zip files, the disk space can be freed up using the following command to delete the files:
[root@localhost WebSphere855]# rm -rf *.zip
The procedure is now followed using ResearchGate DOI (IBM Security Directory Services
6.4- Installation on RHEL 8.0): https://doi.org/10.13140/RG.2.2.33527.57761
Which is described, with full screenshots, starting at page 35 for the downloads and from page 58 through to page 93. The list of Fix Packs available are displayed as illustrated in Figure 6.8:
