memcached安裝

1. 下載, memcached需要先安裝libevent

memcached的下載地址:memcached/download.bml

libevent的下載地址 :~provos/libevent/

2. 安裝libevent

java 程式碼
  1. # tar xzvf libevent-1.3c.tar.gz
  2. # cd libevent-1.3c
  3. # ./configure --prefix=/home/mahaibo/install
  4. # make
  5. # make install

檢查是否安裝成功:

#cd /home/mahaibo/install/lib

如果有libevent-1.3c.so.1 libevent-1.3c.so.1.0.3 libevent.a libevent.la libevent.so

這幾個檔案存在，說明安裝成功

3.安裝memcached

java 程式碼
  1. # tar xzvf memcached-1.2.2.tar.gz
  2. # cd memcached-1.2.2
  3. # ./configure --with-libevent=/home/mahaibo/install --prefix=/home/mahaibo/installmemcache
  4. # make
  5. # make install

檢查是否安裝成功:

#cd /home/mahaibo/installmemcache/bin

如果memcached memcached-debug這2個檔案存在，說明安裝成功

4.執行

java 程式碼
  1. #cd /home/mahaibo/installmemcache/bin
  3. # ./memcached -h

如果出現：

java 程式碼
  1. memcached 1.2.2
  2. -p TCP port number to listen on (default: 11211)
  3. -U UDP port number to listen on (default: 0, off)
  4. -s unix socket path to listen on (disables network support)
  5. -l interface to listen on, default is INDRR_ANY
  6. -d run as a daemon
  7. -r maximize core file limit
  8. -u assume identity of (only when run as root)
  9. -m max memory to use for items in megabytes, default is 64 MB
  10. -M return error on memory exhausted (rather than removing items)
  11. -c max simultaneous connections, default is 1024
  12. -k lock down all paged memory
  13. -v verbose (print errors/warnings while in event loop)
  14. -vv very verbose (also print client commands/reponses)
  15. -h print this help and exit
  16. -i print memcached and libevent license
  17. -b run a managed instanced (mnemonic: buckets)
  18. -P save PID in , only used with -d option
  19. -f chunk size growth factor, default 1.25
  20. -n minimum space allocated for key+value+flags, default 48

說明安裝成功，並且路徑配置正確。

有可能會出現：

java 程式碼
  1. memcached: error while loading shared libraries: libevent-1.3c.so.1: cannot open shared object file: No such file or directory

說明 沒有找到檔案：libevent-1.3c.so.1

解決辦法：

第一步. 檢視下lib路徑:

java 程式碼
  1. LD_DEBUG=libs /home/mahaibo/installmemcache/bin/memcached -v

結果為：

java 程式碼

  59. /home/mahaibo/installmemcache/bin/memcached: error while loading shared libraries: libevent-1.3c.so.1: cannot open shared object file: No such file or directory

第二步. 將libevent-1.3c.so.1複製到任何一個列出的lib 下就可以了。

或者 軟連結

java 程式碼
  1. ln -s /Data/libevent/lib/libevent-1.3b.so.1 /usr/lib/libevent-1.3c.so.1

或者 修改vi /etc/profile檔案。

java 程式碼
  1. export LIBRARY_PATH=:/usr/local/lib:"/usr/local/BerkeleyDB.4.3/lib":/usr/local/lib:/opt/Ice-3.1/lib:/usr/lib:/home/mahaibo/install/lib

其實還有一辦法，用find查詢該so檔案，將存在的路徑加在 LIBRARY_PATH後面就可以的！

啟動服務 ：

java 程式碼

  1. ./memcached -d -m 10 -u root -l 192.168.40.4 -p 12000 -c 256 -P /tmp/memcached.pid

引數說明:

-d選項是啟動一個守護程式
-m是分配給Memcache使用的記憶體數量，單位是MB，我這裡是10MB
-u是執行Memcache的使用者，我這裡是root
-l是監聽的伺服器IP地址
-p是設定Memcache監聽的埠,最好是1024以上的埠
-c選項是最大執行的併發連線數，預設是1024，按照你伺服器的負載量來設定
-P是設定儲存Memcache的pid檔案
