Repcached is memcached which implemented multi master asynchronous replication feature. Download source code.
Repcached key features
- Multi master replication.
- Asynchronous data repliacation.
- Support all memcached command (set, add, delete, incr/decr, flush_all, cas)
Suppose you have 2 servers with IP are 11.11.11.11 and 22.22.22.22
Step 1: Install on each node:
Step 1.1: Install requirement
yum install libevent-dev -y
Step 1.2: install repcached
Install repcached 2.2.1 for memcached 1.2.8
Method 1:
wget http://jaist.dl.sourceforge.net/project/repcached/repcached/2.2.1-1.2.8/memcached-1.2.8-repcached-2.2.1.tar.gz tar xvzf memcached-1.2.8-repcached-2.2.1.tar.gz cd memcached-1.2.8-repcached-2.2.1 ./configure --enable-replication make make install
For CentOS 64 bits
./configure --enable-64bit --enable-replication
Method 2:
git clone https://github.com/yokogawa-k/repcached.git cd repcached ./configure --enable-64bit --enable-replication make make install
Instal repcached 2.3.1 for Memcached 1.4.13
Method 1:
git clone https://github.com/kspe/repcached.git cd repcached ./configure --enable-64bit --enable-replication make make install
result:
[root@tutorialspots ~]# yum install git libevent-devel -y

Done, now you have memcached installed at here: /usr/local/bin/memcached
Method 2:
git clone -b repcached https://github.com/mdounin/memcached.git cd memcached ./configure --enable-64bit --enable-replication make make install
Step 1.3: create file /etc/sysconfig/memcached with content:
PORT="11213" USER="root" MAXCONN="4096" CACHESIZE="4096" OPTIONS="-P /var/run/memcached.pid -x THIS.IS.MASTER.IP -X masterport"
Use your own master IP and master replication port (default master replication port is 11212)
For server 11.11.11.11 you use:
OPTIONS="-P /var/run/memcached.pid -x 22.22.22.22"
For server 22.22.22.22 you use:
OPTIONS="-P /var/run/memcached.pid -x 11.11.11.11"
Note 1: use PORT different than master replication port
Note 2: The replication port has to be the same on both machines
Step 1.4:create file /usr/lib/systemd/system/memcached.service
[Unit] Description=Memcached Before=httpd.service After=network.target [Service] Type=simple EnvironmentFile=-/etc/sysconfig/memcached ExecStart=/usr/local/bin/memcached -u $USER -p $PORT -m $CACHESIZE -c $MAXCONN $OPTIONS [Install] WantedBy=multi-user.target
Step 1.5:
service memcached start
Step 1.6: open port (port replication and port memcached)
iptables -I INPUT -p tcp --dport 11213 -j ACCEPT iptables -I INPUT -p tcp --dport 11212 -j ACCEPT service iptables save
or specify ip address of other server
iptables -I INPUT -p tcp -s 22.22.22.22 --dport 11213 -j ACCEPT iptables -I INPUT -p tcp -s 22.22.22.22 --dport 11212 -j ACCEPT service iptables save
Step 2: Example of usage:
Server 22.22.22.22:
[root@22.22.22.22 ~]# telnet 127.0.0.1 11213 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. set a 0 0 1 b STORED get b VALUE b 0 1 c END
Server 11.11.11.11:
[root@11.11.11.11 ~]# telnet 127.0.0.1 11213 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. get a VALUE a 0 1 b END set b 0 0 1 c STORED
