Compiling and installing Postfix-2.10.10

First, uninstall the original postfix:

[[Email protected] ~]# service postfix stop

[Email protected] ~]# chkconfig postfix off

[Email protected] ~]# rpm-e postfix--nodeps

Second, in order to achieve virtual user authentication based on MySQL, first install MySQL(I am here by compiling the installation MySQL-5.6.33(Universal binary format))

1. unzip the downloaded package to /usr/local and enter this directory

[Email protected] ~]# tar XF mysql-5.6.33-linux-glibc2.5-i686.tar.gz-c/usr/local/

[Email protected] ~]# cd/usr/local/

2. Create a link to the extracted directory and enter this directory

[[email protected] local]# ln-sv mysql-5.6.33-linux-glibc2.5-i686 MySQL

[[Email protected] local]# CD MySQL

3. Create a MySQL user (make it a system user) and MySQL group

[[email protected] mysql]# groupadd-r-G 306 MySQL

[[email protected] mysql]# useradd-g 306-r-u 306 mysql

4. Make all files under MySQL belong to MySQL user and MySQL group

[Email protected] mysql]# chown-r mysql.mysql/usr/local/mysql/*

5. prepare a partition in advance to create a logical volume (I use /dev/sda5here) to create a logical volume on this partition and enable it to be mounted automatically for use.

[Email protected] mysql]# PVCREATE/DEV/SDA5

[Email protected] mysql]# vgcreate MYVG/DEV/SDA5

[Email protected] mysql]# lvcreate-n mydata-l 512M MYVG

[Email protected] mysql]# mke2fs-j/dev/myvg/mydata

#vim/etc/fstab, add the following:

/dev/myvg/mydata/mydata ext3 defaults 0 0

[Email protected] mysql]# Mkdir/mydata

[Email protected] mysql]# mount-a

6. Create a data directory and make it a MySQL user and MySQL group, no one else has permission

[Email protected] mysql]# Mkdir/mydata/data

[Email protected] mysql]# chown-r mysql:mysql/mydata/data/

[Email protected] mysql]# chmod o-rw/mydata/data/

7. prepare to install the required development environment

[[email protected] mysql]# yum-y install GCC

8. Ready to start Installation

[[email protected] MySQL] #scripts/mysql_install_db--user=mysql--datadir=/mydata/data

9. After the installation is complete, change the permissions of all files under /usr/local/mysql for Security

[Email protected] mysql]# chown-r root.

10. Prepare the startup script and enable it to boot automatically

[email protected] mysql]# CP support-files/mysql.server/etc/init.d/mysqld

[Email protected] mysql]# chkconfig--add mysqld

[Email protected] mysql]# chkconfig--list mysqld

11. Edit the database configuration file

[email protected] mysql]# CP support-files/my-default.cnf/etc/my.cnf

#vim/etc/my.cnf, modify and add the following:

DataDir =/mydata/data

12. Provide the environment variables required to execute the relevant commands

[Email protected] ~]# vim/etc/profile.d/mysql.sh

Add the following content:

Export path= $PATH:/usr/local/mysql/bin

13. Now that theMySQL service configuration is complete, you can start the test

[[Email protected] ~]# service mysqld start

Third, compile and install postfix,(I use postfix-2.10.10.tar.gzhere, related packages can go to postfix Website download)

1. Unzip

[Email protected] ~]# Tar XF postfix-2.10.10.tar.gz

[Email protected] ~]# CD postfix-2.10.10

2. Establish postfix and postdrop groups and users

[Email protected] postfix-2.10.10]# groupadd-g 2525 postfix

[Email protected] postfix-2.10.10]# useradd-g postfix-u 2525-s/sbin/nologin-m postfix

[Email protected] postfix-2.10.10]# groupadd-g 2526 postdrop

[Email protected] postfix-2.10.10]# useradd-g postdrop-u 2526-s/sbin/nologin-m postdrop

3. Install the required packages

[email protected] postfix-2.10.10]# Yum install Cyrus-sasl-devel

[email protected] postfix-2.10.10]# Yum install Db*-devel

[Email protected] postfix-2.10.10]# yum-y install Openssl-devel

4. Installation

[email protected] postfix-2.10.10]# make makefiles ' Ccargs=-dhas_mysql-i/usr/local/mysql/include-duse_sasl_auth- Duse_cyrus_sasl-i/usr/include/sasl-duse_tls ' AUXLIBS=-L/USR/LOCAL/MYSQL/LIB-LMYSQLCLIENT-LZ-LM-L/USR/LIB/SASL2 -lsasl2-lssl-lcrypto '

Interpretation:

Ccargs: Indicates the header file location,ccargs=-dhas_mysql indicates that the MYSQL -enabled connection can

-i/usr/include/mysql indicates the mysql header file location

-duse_sasl_auth enabling SASL authentication

-I/USR/INCLUDE/SASL indicates SASL header file Location

-DUSE_TLS enabling SMTP to support the Smtps Protocol

Auxlibs: Indicates the location of the library file,-l/usr/lib/mysql indicates the MySQL library file location

-lmysqlclient indicates the MySQL client library file

-lz compressing library files

-LM Module Library file

-lsslssl 's library file

[[email protected] postfix-2.10.10]# make

[[email protected] postfix-2.10.10]# make install

Follow the prompts below to enter the relevant path (the [] number is the default value, "]" After the input value, the omitted representation takes the default value )

Install_root: [/]/

TempDir: [/root/postfix-2.10.10]/tmp/postfix

Config_directory: []/etc/postfix

Command_directory: []/usr/sbin

Daemon_directory: []/usr/libexec/postfix

Data_directory: []/var/lib/postfix

Html_directory: [] No

Mail_owner: [] postfix

Mailq_path: []/usr/bin/mailq

Manpage_directory: []/usr/local/man

Newaliases_path: []/usr/bin/newaliases

Queue_directory: []/var/spool/postfix

Readme_directory: [] No

Sendmail_path: []/usr/sbin/sendmail

Setgid_group: [] Postdrop

You may encounter the following issues during this process:

Libmysqlclient.so.18:cannot open Shared object file:no such file or directory

1). First confirm whether there is libmysqlclient.so.18 this file under /usr/local/mysql/lib/ .

Ll/usr/local/mysql/lib/|grep libmysqlclient.so.18

2). Modify the ld.so.conf file

echo "/usr/local/mysql/lib" >>/etc/ld.so.conf

Then execute the ldconfig to make it effective

5. now it's time to start the service.

[[email protected] ~]# postfix start

Complete!
