After the package installation is complete, the next step is to make
sure that the system can properly find the files. If you set up your
login scripts as recommended in The
Bash Shell Startup Files, update the environment by creating the
openjdk.sh
script, as the root
user:
cat > /etc/profile.d/openjdk.sh << "EOF"
# Begin /etc/profile.d/openjdk.sh
# Set JAVA_HOME directory
JAVA_HOME=/opt/jdk
# Adjust PATH
pathappend $JAVA_HOME/bin
# Add to MANPATH
pathappend $JAVA_HOME/man MANPATH
# Auto Java CLASSPATH: Copy jar files to, or create symlinks in, the
# /usr/share/java directory. Note that having gcj jars with OpenJDK 8
# may lead to errors.
AUTO_CLASSPATH_DIR=/usr/share/java
pathprepend . CLASSPATH
for dir in `find ${AUTO_CLASSPATH_DIR} -type d 2>/dev/null`; do
pathappend $dir CLASSPATH
done
for jar in `find ${AUTO_CLASSPATH_DIR} -name "*.jar" 2>/dev/null`; do
pathappend $jar CLASSPATH
done
export JAVA_HOME
unset AUTO_CLASSPATH_DIR dir jar
# End /etc/profile.d/openjdk.sh
EOF
For allowing mandb to
include the OpenJDK man pages in its database, issue, as the
root
user:
cat >> /etc/man_db.conf << "EOF" &&
# Begin Java addition
MANDATORY_MANPATH /opt/jdk/man
MANPATH_MAP /opt/jdk/bin /opt/jdk/man
MANDB_MAP /opt/jdk/man /var/cache/man/jdk
# End Java addition
EOF
mkdir -p /var/cache/man
mandb -c /opt/jdk/man
