This page shows how to install ActiveMQ on CentOS 6

You must have a CentOS machine already set up in accordance with the the “Install CentOS 6” guide.

Download the latest Linux tar file from the ActiveMQ website and put it in /tmp on the target server

Run the following as root

lvcreate -L 1G datavg -n activemq
mkfs -t ext4 /dev/mapper/datavg-activemq
mkdir /activemq
echo '/dev/mapper/datavg-activemq /activemq           ext4    defaults        1 2' >> /etc/fstab
mount -a

useradd activemq
passwd activemq

chown activemq:activemq /activemq/
su - activemq

cd /activemq/
tar xf apache-activemq-5.11.1-bin.tar.gz
ln -s apache-activemq-5.11.1 activemq
rm -f apache-activemq-5.11.1-bin.tar.gz

Enable the use of JMXThis will enable the use of some admin related commands when using /activemq/activemq/bin/activemq and /activemq/activemq/bin/activemq. The following commands are supported http://activemq.apache.org/activemq-command-line-tools-reference.html

vi /activemq/activemq/conf/activemq.xml

As root create /etc/init.d/activemq and put the following in the file Set the managementContext element to True

<managementContext>
 <managementContext createConnector="true"/>
</managementContext>

Also, in the same file, edit

                <storeUsage>
                    <storeUsage limit="100 gb"/>
                </storeUsage>
                <tempUsage>
                    <tempUsage limit="10 gb"/>
                </tempUsage>

to

                <storeUsage>
                    <storeUsage limit="500 mb"/>
                </storeUsage>
                <tempUsage>
                    <tempUsage limit="100 mb"/>
                </tempUsage>

No configure the username/password in activemq by adding the following (change password value as appropriate) to /activemq/activemq/conf/jetty-realm.properties Replace

admin: admin, admin

With

wsxadm: Password, admin

The format is “username: password, rolename”

As root create /etc/init.d/activemq and put the following in the file

#!/bin/bash
# chkconfig: 2345 95 20
# description: Script to Start | Restart activemq

case $1 in
start)
COMMAND="/activemq/activemq/bin/activemq start"
/bin/su activemq -c "$COMMAND"
;;
stop)
COMMAND="/activemq/activemq/bin/activemq stop"
/bin/su activemq -c "$COMMAND"
;;
restart)
COMMAND="/activemq/activemq/bin/activemq stop"
/bin/su activemq -c "$COMMAND"
COMMAND="/activemq/activemq/bin/activemq start"
/bin/su activemq -c "$COMMAND"
;;
esac
exit 0

chmod u+x /etc/init.d/activemq
chkconfig --add activemq
chkconfig activemq on

By default, the admin page runs on port 8161. We put this behind the Nginx reverse proxy and access it over https on port 8162.

Open the firewall

iptables -I INPUT -m state --state NEW -m tcp -p tcp --dport 8162-j ACCEPT

service iptables save
service iptables restart

Add the following at the end of /etc/nginx/conf.d/default.d (Change “internal” as appropriate).

server {
    listen       8162;
    server_name  internal.example.com;
    ssl          on;
    ssl_certificate      /etc/nginx/conf.d/internal.crt;
    ssl_certificate_key  /etc/nginx/conf.d/internal.key;

    ssl_session_timeout  5m;

    ssl_protocols TLSv1.2;
    ssl_ciphers 'AES256+EECDH:AES256';

    ssl_prefer_server_ciphers   on;
    ssl_session_cache shared:SSL:10m;

    #charset koi8-r;
    access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        proxy_pass http://mqadmin;
        proxy_set_header    X-Forwarded-Host $host;
        proxy_set_header    X-Forwarded-Server $host;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header    X-Real-IP $remote_addr;
        proxy_redirect      off;
        proxy_set_header Host $host;
        proxy_connect_timeout       900;
        proxy_send_timeout          900;
        proxy_read_timeout          900;
        send_timeout                900;
    }


    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
       root   /usr/share/nginx/html;
    }
}

Add the following to the top of /etc/nginx/conf.d/default.d

upstream mqadmin {
    server 127.0.0.1:8161;
}

Restart Nginx

service nginx restart

You can now access the admin page on

https://internal.example.com:8162/admin/
