Starting Apache Httpd at Boot time with Zero intervention, CentOS and authbind

Question

I want to start Apache Httpd when Linux starts (with Zero intervention like submitting the root password, I don't want write the root password to start the apache service!!!)

Later of Apache was installed:

# ./configure --prefix=/usr/local/httpd ... --with-included-apr --with-included-apr-util -with-pcre=/usr/local/pcre --with-z=/usr/local/zlib
# make
# make install

I made this (I created an user named httpd with root group):

# useradd -g root -r -c "Httpd User" -s /sbin/nologin httpd
# chown -hvR httpd:root /usr/local/httpd/

I changed the privileges:

# chown -hvR httpd:root /usr/local/httpd/bin/

# ls -ARl --group-directories-first /usr/local/httpd/bin/
/usr/local/httpd/bin/:

I created an service for this reason: (short) like this:

SERVICE_HOME=/usr/local/httpd
SERVICE_USER=httpd
SERVICE_NAME=Httpd
SHUTDOWN_WAIT=20

service_pid() {
  echo `ps aux | grep "$SERVICE_USER" | grep "$SERVICE_HOME" | grep -v grep | head -1 | awk '{ print $2 }' `
}

start() {
  pid=$(service_pid)
  if [ -n "$pid" ] 
  then
echo "$SERVICE_NAME is already running (pid: $pid)"
  else
# Start httpd
echo "Starting $SERVICE_NAME"
/bin/su -p -s /bin/sh $SERVICE_USER $SERVICE_HOME/bin/apachectl start
#/bin/su -p -s /bin/sh httpd authbind /usr/local/httpd/bin/apachectl start
  fi
  return 0
}

But was impossible:

I wasd trying with authbind

http://ftp.debian.org/debian/pool/main/a/authbind/authbind_1.2.0.tar.gz

# tar zxvf /.../authbind_1.2.0.tar.gz -C /usr/local/
# cd /usr/local/authbind-1.2.0
# make
# make install

# ls -ARl /etc/authbind/

Trying test from the prompt (I need that apache starts with httpd user!!!)

# /bin/su -p -s /bin/sh httpd authbind /usr/local/httpd/bin/apachectl start
/usr/local/bin/authbind: /usr/local/bin/authbind: cannot execute binary file
# /bin/su -p -s /bin/sh httpd exec authbind /usr/local/httpd/bin/apachectl start
sh: exec: No such file or directory
# /bin/su -p -s /bin/sh httpd exec authbind --deep /usr/local/http/bin/apachectl start
/bin/su: unrecognized option '--deep'
Try `/bin/su --help' for more information.
# 

---

Question 1:

works authbind in RHEL/CentOS/Fedora Environment?

---

Question 2:

What must be my commands? Is needed exec or --deep together with authbind?

---

testing authbind with root user has not problem!

# authbind /usr/local/httpd/bin/apachectl start
# authbind /usr/local/httpd/bin/apachectl stop
#

Question 3:

Is needed /bin/su, -p, -s and /bin/sh with httpd user?

Answer 1

you must to use the new version of authbind supporting IPV6:
http://ftp.debian.org/debian/pool/main/a/authbind/

or

http://www.filewatcher.com/m/authbind_2.1.1.tar.gz.14407-0.html

ftp://ftp.debian.com/debian/pool/main/a/authbind/authbind_2.1.1.tar.gz

tar zxvf /home/.../authbind_2.1.1.tar.gz -C /your/path/
cd /your/path/authbind-2.1.1
make
make install

About the user and group, the user is not necessary to belong to root group...

useradd -r -c "Httpd User" -s /sbin/nologin httpd
chown -hR httpd: /usr/local/httpd/

Now, the autho

touch /etc/authbind/byport/80
chown httpd: /etc/authbind/byport/80
chmod 755 /etc/authbind/byport/80

Answer 1

I have seen several tutorials Authbind for CentOS, RHEL and Fedora, for some reason... works, then the answer is Yes...

Answer 2

starting the server try this in your script:

/bin/su -p -s /bin/sh httpd -c "/usr/local/bin/authbind /usr/local/httpd/bin/apachectl start"

or

/bin/su -p -s /bin/sh $SERVICE_USER -c "/usr/local/bin/authbind $SERVICE_HOME/bin/apachectl start"

stoping the server try this in your script:

/bin/su -p -s /bin/sh httpd -c "/usr/local/bin/authbind /usr/local/httpd/bin/apachectl stop"

or

/bin/su -p -s /bin/sh $SERVICE_USER -c "/usr/local/bin/authbind $SERVICE_HOME/bin/apachectl stop"

About of your Question 3, please check: su and sh
