Memcachedb Application Guide 2: Compilation and Installation

From: http://blog.csdn.net/simonlsy/article/details/2027940

Like memcachedb, network socket data processing depends on libevent. Therefore, you need to download three installation packages, libevent and Berkeley, before installation.
DB and memcachedb.

Libevent download page: http://monkey.org /~ Provos/libevent/, just download the latest stable version.

Berkeley dB download page: http://www.oracle.com/technology/software/products/berkeley-db/index.html needs to install version 4.6

Memcachedb download page: http://code.google.com/p/memcachedb/ download the latest version 0.1.0

Install libevent and Berkeley dB in sequence. The standard is Linux.

[===== Libevent ===]

Tar-zxvf libevent-1.3e.tar.gz

CD libevent-1.3e

./Configure

Make & make install

[===== Berkeley dB ===]

Tar-zxvf db-4.6.19.tar.gz

# You need to enter the compiling environment of a specific operating system. There are some differences in the compilation of more general software.

CD db-4.6.19/build_unix/

# Then you can start compiling

../Dist/configure

Make & make install

# If no special installation path is specified and compilation is complete, add the path of the Berkeley dB Runtime Library to the system configuration.

Echo "/usr/local/berkeleydb.4.6/lib/">/etc/lD. So. conf

# Reload the system LD Runtime Library

Ldconfig

[====== Memcachedb ====]

Tar-zxvf memcachedb-0.1.0.tar.gz

CD memcachedb-0.1.0

# If the length of the key value of the content you want to store and the length of a single content changes, you need to change the memcachedb. h file.

Vim memcachedb. h

//////////////////////////////////////// ////////////////////

# Define end_len 32 ----> This is the maximum length of key + value.
# Define end_len_str "31" ---> This is the maximum length of the key.

//////////////////////////////////////// /////////////////

# By default, the key value is only reserved for 31 bytes. the maximum number of bytes for a single data record is 32.

# For example, if you need to use this method to store text content data, assume that your key value is a 32-byte MD5 and a single data record can be up to 10 KB, you can set

//////////////////////////////////////// ////////////////////

# Define end_len 102400 ----> This is the maximum length of key + value.
# Define end_len_str "32" ---> This is the maximum length of the key.

# Make directly after modification

Make

# After compilation, copy the generated executable memcachedb to/usr/sbin/

CP-F memcachedb/usr/sbin/

# Start memcachedb

# First, read/write merge mode, that is, no secondary copy, that is, read and write, no redundant backup

# Second, read/write splitting/backup mode

# Master server 192.168.0.1 read/write listener 11211, synchronized through port 31211, do not occupy busy master service port

# The secondary server 192.168.0.2 listens to port 21212 read-only, synchronizes data from Port 31211 of 192.168.0.1, and opens another port 31212 to provide the data synchronization service.
