Install memcached in linux

1. download memcached and libevent to the/tmp Directory: # cd/tmp # sudowgethttp: // container /~ Provos/libevent-

 

1. download memcached and libevent respectively and put them in the/tmp Directory:

# Cd/tmp

# Sudo wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz

# Sudo wget http://www.monkey.org /~ Provos/libevent-1.2.tar.gz

2. install libevent first:

# Tar zxvf libevent-1.2.tar.gz

# Cd libevent-1.2

#./Configure-prefix =/usr // if an error occurs, install gcc and run sudo apt-get install gcc.

# Make // if an error occurs, install make by executing sudo apt-get install make.

# Sudo make install

3. test whether the libevent is successfully installed:

# Ls-al/usr/lib | grep libevent

Lrwxrwxrwx 1 root 21 11 ?? Libevent-1.2.so.1> libevent-1.2.so.1.0.3

-Rwxr-xr-x 1 root 263546 11 ?? Libevent-1.2.so.1.0.3

-Rw-r-1 root 454156 11 ?? 12 libevent.

-Rwxr-xr-x 1 root 811 11 ?? Libevent. la

Lrwxrwxrwx 1 root 21 11 ?? 12 libevent. so-> libevent-1.2.so.1.0.3

Indicates that the installation is successful.

4. install memcached and specify the libevent installation location during installation:

# Cd/tmp

# Tar zxvf memcached-1.2.0.tar.gz

# Cd memcached-1.2.0

#./Configure-with-libevent =/usr

# Make

# Sudo make install

5. test whether memcached is successfully installed:

# Ls-al/usr/local/bin/mem *

-Rwxr-xr-x 1 root 137986 11 ?? 12 :39/usr/local/bin/memcached

-Rwxr-xr-x 1 root 140179 11 ?? 12 :39/usr/local/bin/memcached-debug

6. start the Memcache server:

#/Usr/local/bin/memcached-d-m 10-u root-l 192.168.1.100-p 12000-c 256-P/tmp/memcached. pid

-D option is to start a daemon,

-M indicates the amount of memory allocated to Memcache. the unit is MB. here I am 10 MB,

-U is the user who runs Memcache. here I am root,

-L is the IP address of the listening server. if there are multiple IP addresses, I have specified the IP address 192.168.0.200,

-P is the port for Memcache listening. I have set Port 12000 here, preferably port 1024 or above,

-The "c" option is the maximum number of concurrent connections. the default value is 1024. I have set 256 here, which is based on the load of your server,

-P is the pid file for saving Memcache. here I save it in/tmp/memcached. pid,

To end the Memcache process, run:

# Kill 'cat/tmp/memcached. Pi'

7. test Memcached:

[Root @ localhost/] # telnet 192.168.141.64 12000.

Trying 192.168.141.64...

Connected to 192.168.141.64 (192.168.141.64 ).

Escape character is '^]'.

After the preceding characters are displayed, type:

Set key1 0 60 4

Zhou

STORED

Get key1

VALUE key1 0 4

Zhou

END

So far, Memcached has been installed successfully!

8. to enable automatic startup, add a line to/etc/rc. d/rc. local. the following command

/Usr/local/memcached/bin/memcached-d-m 10-p 12000-u apache-c 256

Some of the above can be referred to: that is, when the ip address is not specified, the default is local. User: the best choice is apache or deamon.

In this way, it is the service of the user and the user who starts the service.
