Install and configure qmail + LDAP instances in Linux

In Linux, qmail + LDAP is used to install and configure the instance-Linux Enterprise Application-Linux server application information. For details, refer to the following section. Currently, there are not many qmail + LDAP configurations on the Internet, and most of them are in English. The configuration of qmail and openldap does not have detailed configuration documents. The qmail + LDAP server was configured some time ago due to the working relationship. Now we will sort it out for your reference. I hope this will help you.

Su-
Umask 022
Cd/usr/local/src/qmail
Tar zxvf qmail-1.03.tar.gz
Tar xvf ucspi-tcp-0.88.tar.gz
Tar zxvf daemontools-0.70.tar.gz
Tar zxvf checkpassword-0.90.tar.gz
The unwrapped package should be in the qmail-1.03, ucspi-tcp-0.88, daemontools-0.70 and checkpassword-0.90 directory and enter the qmail directory.
Cd qmail-1.03
Create an appropriate installation directory
Because the qmail installer generates the required sub-directories, you only need to generate the "home" directory required for installation:
Mkdir/var/qmail
Ln-s/usr/man/var/qmail/man
Mkdir/etc/qmail
Ln-s/etc/qmail/var/qmail/control
Ln-s/usr/sbin/var/qmail/bin
Generate users and groups required for qmail Installation
# Groupadd nofiles
# Useradd-g nofiles-d/var/qmail/alias
# Useradd-g nofiles-d/var/qmail qmaild
# Useradd-g nofiles-d/var/qmail qmaill
# Useradd-g nofiles-d/var/qmail qmailp
# Groupadd qmail
# Useradd-g qmail-d/var/qmail qmailq
# Useradd-g qmail-d/var/qmail qmailr
# Useradd-g qmail-d/var/qmail qmails
Compile and install
Now you can compile and install qmail:
Make setup check
After the compilation and installation are complete, you must configure the DNS. If the DNS configuration is correct, run the following command:
./Config
If config cannot find the host name in DNS, run the config-fast script:
./Config-fast longshine. com
Qmail is now installed. The following describes how to start and configure qmail.
Install ucspi-tcp
Go to the ucspi-tcp directory:
Cd/usr/local/src/qmail/ucspi-tcp-0.88
Make
Make setup check
