Apache2 on Ubuntu for load Balancing

Experimental environment

Virtual Machine Three

TOMCAT1 192.168.103.192 Tomcat+mysql

TOMCAT2 192.168.103.195 Tomcat

Apache2 192.168.103.217 apache2

The Tomcat directory is placed in the/data/software

First, install MySQL and Redis, Tomcat on the TOMCAT1

installation of MySQL

1. Install MySQL dependent packages

Apt-get-y install gcc libncurses5-dev zlib1g-dev Libssl-dev Bison build-essential

2.mysql5.5 gave up./configure precompiled method, instead of cmake, so we have to install CMake first.

wget http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz

TAR-ZVXF cmake-2.8.7.tar.gz

CD cmake-2.8.7

./configure

Make && make install

3. Download MySQL source package, add compression after compiling and install MySQL.

Mkdir/var/lib/mysql/var/log/mysql creating a MySQL Directory

wget http://downloads.mysql.com/archives/mysql-5.5/mysql-5.5.30.tar.gz

TAR-ZVXF mysql-5.5.30.tar.gz

CD mysql-5.5.30

CMake. -dcmake_install_prefix=/usr/local/mysql-dmysql_datadir=/var/lib/mysql-ddefault_charset=utf8-ddefault_collation =utf8_general_ci-dwith_innobase_storage_engine=1-dextra_charsets=all-dwith_ssl=system-dwith_debug=0

Make && make install

Note: For csv,myisam,myisammrg,heap in CMake, it is not necessary to explicitly specify the name of the storage engine because they are mandatory to install.

4. Create user groups and users, create related directories and empower them.

#创建mysql组和mysql用户

Groupadd MySQL;

Useradd-r-g MySQL MySQL or useradd-s/sbin/nologin MySQL

chmod +w/usr/local/mysql

Chown-r Mysql:mysql/usr/local/mysql/var/lib/mysql/var/log/mysql

5. Initialize the database and assign the database the right

/usr/local/mysql/scripts/mysql_install_db--user=mysql--pid-file=/var/lib/mysql/mysql.pid--datadir=/var/lib/ mysql/--basedir=/usr/local/mysql

Empowerment:

Chown-r Mysql:mysql/var/lib/mysql

6. Modify the configuration file.

Copy/etc The support-files/my-medium.cnf under the extracted tar package and replace it with the/my.cnf. (Copy the configuration as required)

CP SUPPORT-FILES/MY-MEDIUM.CNF/ETC/MY.CNF

Under #在 [client], modify the socket value to/var/lib/mysql/mysql.sock,

Modify the socket value under Mysqld to/var/lib/mysql/mysql.sock, and specify the MySQL directory, MySQL data directory, mysql error log directory, configured as follows, and set the database encoding to UTF-8 modified save exit

[Client]

Socket =/var/lib/mysql/mysql.sock

# The MySQL server

[Mysqld]

Port = 3306

Socket =/var/lib/mysql/mysql.sock

Basedir =/usr/local/mysql

DataDir =/var/lib/mysql/

Log-error =/var/log/mysql/mysql-error.log

Pid-file =/var/lib/mysql/mysql.pid

Character-set-server = UTF8

7. Set up MySQL boot.

Start MySQL

/usr/local/mysql/bin/mysqld_safe &

Ps-a|grep MySQL

Set up MySQL boot.

CP Support-files/mysql.server/etc/init.d/mysql

chmod +x/etc/init.d/mysql

Chkconfig--add MySQL

Chkconfig MySQL on

Test if MySQL can start, pause, restart

Service MySQL restart (start|stop|restart)

or/etc/init.d/mysql restart (start|stop|restart)

Add part of the MySQL command to/usr/bin:

ln/usr/local/mysql/bin/mysql/usr/bin/

ln/usr/local/mysql/bin/mysqladmin/usr/bin/

ln/usr/local/mysql/bin/mysqldump/usr/bin/

After the installation is successful, set the MySQL root password

Mysql>set password =password (' 123456 ');

Mysql>Grant all privileges on * * to ' myuser ' @ '% ' identified by ' MyPassword ' with GRANT OPTION; can be connected from any host to mysql

Mysql>flush privileges;

Ii. installation of Tomcat

1. First configure the Java environment

#vi ~/.BASHRC Add a parameter at the end

Export java_home=/data/software/jdk1.7.0_79

Export path= $JAVA _home/bin: $PATH

Export classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

#java-version

Java Version "1.7.0_79"

Java (TM) SE Runtime Environment (build 1.7.0_79-b15)

Java HotSpot (TM) 64-bit Server VM (build 24.79-b02, Mixed mode)

2. Unzip the configuration Tomcat

#tar ZXVF apache-tomcat-7.0.62.tar.gz

#cd apache-tomcat-7.0.62/webapps/

Then upload the login system login, and then specify the database to the local database address (here according to your needs)

Go to the Bin directory of Tomcat to start the service

Tomcat2 only on Tomcat and the above steps, login configuration to point to 192.168.103.192 this database

1 Installing Apache2

Apt-get Install Apache2

Service Apache2 Stop

2 Loading the agent module

A2enmod proxy proxy_ajp proxy_balancer proxy_connect proxy_ftp proxy_http lbmethod_byrequests

3 Modifying configuration sudo vi/etc/apache2/mods-enabled/proxy.conf

Proxyrequests OFF

<proxy *>

Order Deny,allow

Deny from all

#Allow from. your_domain.com

</Proxy>

4 Modifying Configuration vim/etc/apache2/sites-available/000-default.conf

Load Balancing Configuration

Proxyrequests OFF

proxypass/balancer://proxy/

<proxy balancer://proxy>

Order Deny,allow

Allow from all

Balancermember http://192.168.103.192:8080

Balancermember http://192.168.103.195:8080

</Proxy>

</VirtualHost>

Service Apache2 Restart

Then access address 192.168.103.217/login first visit will jump to 192.168.103.192 the second time will go to 192.168.103.195, the experiment is complete.
