Cfengine/228/client

Prepare

Operating system

Scientific Linux version 4.5 64 bit

Optimizing the configuration: 

Use minimal operating system installation without firewall.
To verify installed packages use the command 
rpm -qa | grep package_name
Install the following additional packages:
yum -y install wget yum rpm make gcc gcc-c++ tar sed zlib openssl
After the installation is complete, turn off any unnecessary services (like gpm, sendmail, cups, haldaemon, messagebus, pcmcia, anacron, atd) with the following command: 
chkconfig <SERVICE> off

Configure the following settings for the server:

Additional software packages

Berkeley DB version 4
OpenSSL (openssl.i686 krb5-libs.i386 openldap.i386 cyrus-sasl.i386 compat-openldap.i386)

Firewall configuration

Port 5308 should be open (how to open port in firewall).

administrator's script: prepare.sh

```
 
```
```
#!/bin/bash
```

# prepare cfengine client for installation

# Dependencies: You must have a working Berkeley DB (version 4)and OpenSSL installation,

```
#with headers and library files. 
```
```
yum -y install db4
```

yum -y install openssl.i686 krb5-libs.i386 openldap.i386 cyrus-sasl.i386 compat-openldap.i386

```
 
```
```
exit 0
```

Install

The following steps are needed to install a Cfengine Client on all middleware frontends and worker nodes as root user:

administrator's script: install.sh

```
 
```
```
#!/bin/bash
```
```
# install cfengine client
```
```
# Set BASE_URL link
```

BASE_URL="http://mirror.scc.kit.edu/downloads/rpms/cfengine/2009.1"

```
 
```
```
# Download packages: 
```
```
cd /tmp
```
```
 
```

#When installing on a Scientific Linux client please use this Package Version:

PACKAGE_VERSION="SL4.5/cfengine/cfengine-2.2.8-1.el4.rf.x86_64"

```
 
```

#When installing on a SuSe (SLES 10)client  please use this Package Version:

PACKAGE_VERSION="SLES10/cfengine/cfengine-2.2.8-15.1.x86_64"

```
 
```
```
# Install
```

rpm -ivh ${BASE_URL}/${PACKAGE_VERSION}.rpm

```
 
```

# If you are installing the Cfengine Client on Scientific Linux you have to do the following:

```
mkdir -p /var/cfengine/outputs 
```
```
chmod go-rx /var/cfengine/outputs
```
```
 
```

# If you are installing the Cfengine Client on Suse (SLES10 SP1) you have to do the following:

```
mkdir /var/cfengine/
```
```
mkdir /var/cfengine/inputs
```
```
mkdir /var/cfengine/outputs 
```
```
mkdir /var/cfengine/ppkeys
```
```
chmod go-rx /var/cfengine/inputs
```
```
chmod go-rx /var/cfengine/outputs
```
```
chmod go-rx /var/cfengine/ppkeys
```

#generate a client key by using the '''cfkey''' command.

Configure

Note: cfengine server IP: xx.xx.x.xx, cfengine client IP: yy.yy.y.yy

administrator's script: configure.sh

```
 
```
```
#!/bin/bash
```
```
# configure cfengine client
```

# key exchange between server and client

```
 
```
```
# copy server public key to client:
```

scp root@xx.xx.x.xx:/var/cfengine/ppkeys/localhost.pub \

root@<b>yy.yy.y.yy</b>:/var/cfengine/ppkeys/root-xx.xx.x.xx.pub

```
 
```
```
# copy client public key to server:
```

scp root@<b>yy.yy.y.yy</b>:/var/cfengine/ppkeys/localhost.pub \

root@xx.xx.x.xx:/var/cfengine/ppkeys/root-<b>yy.yy.y.yy</b>.pub

```
 
```

# copy the first configuration file from server to client:

scp root@xx.xx.x.xx:/var/cfengine/masterfiles/inputs/update.conf \

root@<b>yy.yy.y.yy</b>:/var/cfengine/inputs/

```
 
```
```
# Start cfengine on client
```

# first start of cfengine to get he whole configuration files from server to client:

```
cfagent -q -v --update-only
```
```
 
```

# first start of cfengine to get the files which should be distributed:

```
cfagent -q -v
```
```
cfshow --last-seen 
```
```
cfshow --performance
```
```
 
```
```
exit 0
```

Proceed

To start/stop cfengine use the commands:

administrator's script: proceed.sh

```
 
```
```
#!/bin/bash
```
```
# Start cfengine on client
```

# first start of cfengine to get he whole configuration files from server to client:

```
cfagent -q -v --update-only
```

# start of cfengine to get the files which should be distributed:

```
cfagent -q -v
```
```
cfshow --last-seen 
```
```
cfshow --performance
```
```
 
```
```
exit 0
```

Initial test

Try examining the output:

administrator's script: test.sh

```
 
```
```
#!/bin/bash
```
```
# test cfengine server installation
```
```
# Try examining the output:  
```
```
cfagent -p -d3
```
```
 
```
```
exit 0
```

Update

To update/reinstall/delete cfengine packages, use:

administrator's script: update.sh

```
 
```
```
#!/bin/bash
```
```
#update cfengine
```
```
# Reinstall packages:
```

rpm -Uvh --force package-to-reinstall.rpm

```
 
```
```
# delete installation:
```
