Apache+SSL in Centos

1. Install package
yum install mod_ssl openssl

2. Create CA and generate Cert
# Generate private key 
openssl genrsa -out ca.key 1024 

# Generate CSR 
openssl req -new -key ca.key -out ca.csr

# Generate Self Signed Key
openssl x509 -req -days 365 -in ca.csr -signkey ca.key -out ca.crt

# Move the files to the correct locations
mv ca.crt /etc/pki/tls/certs
mv ca.key /etc/pki/tls/private/ca.key
mv ca.csr /etc/pki/tls/private/ca.csr

3. Config SSL for httpd
Setup the path for the cert and ca key
vi /etc/httpd/conf.d/ssl.conf 
SSLCertificateFile /etc/pki/tls/certs/ca.crt
SSLCertificateKeyFile /etc/pki/tls/private/ca.key

4. Setup Virtual Host in Apache

<virtualhost *:443>
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/ca.crt
SSLCertificateKeyFile /etc/pki/tls/private/ca.key
<Directory /var/www/vhosts/yoursite.com/httpsdocs>
AllowOverride All
</directory>
DocumentRoot /var/www/vhosts/yoursite.com/httpsdocs
ServerName yoursite.com
</virtualhost>

/etc/init.d/httpd restart

vmware remote console on firefox 3.6.x problem

The problem is the vmrc plugin is not available on firefox 3.6.x, it return timeout error. So my solution is just run the vmrc directly, you can follow the steps:

copy the plugin from /usr/lib/vmware/webAccess/tomcat/apache-tomcat-6.0.16/webapps/ui/plugin/ to client site.
on client, just unzip it, (for me, unzip vmware-vmrc-linux-x64.xpi)

after extract, you can see vmware-vmrc in plugin folder, run it directly and give the hostname (e.g: 192.168.0.2:8333), username and password.


Linux:
vmware-vmrc -h [<hostname>] [-u <username> -p <password>] [-M <moid> | <datastore path>]

Windows:
vmware-vmrc.exe -h <hostname> [-u <username> -p <password>] -M <moid> | <datastore path>

You can find the object id (moid) from vmInventory.xml
For example: "C:\Program Files (x86)\Common Files\VMware\VMware Remote Console Plug-in\vmware-vmrc.exe" -h localhost:8333 -M 16

Windows startup no desktop screen -- explorer.exe don't startup

open registry (menu Start -> run (or run Comand prompt): regedit).

open: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ Current
Version \ Winlogon

At right pane there is "Shell". The value of it must be "explorer.exe"

Solution1:
Install with the following command:
C:\Users\Administrator\Downloads\SQLEXPRWT_x64_EN.exe U>setup.exe /ACTION=install /SKIPRULES=PerfMonCounterNotCorruptedCheck


Solution2 (Environment: win vista sp2 32bit):

then you can copy 0404 reg key and create new reg key call 004
Then install again.
