CentOS上安裝Memcache及問題解決

本文記錄一次在CentOS上安裝Memcache的過程，其中也包含了安裝過程當中遇到的錯誤以及相應的解決方法。

Libevent安裝

能夠訪問libevent.org網站下載最新的libevent，本文使用的是libevent-2.0.22-stable

，將下載的tar.gz包放到本身想安裝的目錄下。

解壓縮

[root@dev18 libevent]# tar -zvxf libevent-2.0.22-stable.tar.gz

./configure

進入解壓後的目錄，執行./configure

[root@dev18 libevent]# cd libevent-2.0.22-stable
[root@dev18 libevent]# ./configure

執行後，部分配置顯示的內容以下：

checking for struct sockaddr_storage... yes
checking for struct in6_addr.s6_addr32... yes
checking for struct in6_addr.s6_addr16... yes

通過 配置(./configure)、編譯 (make) 和安裝 (make install) 三個步驟就完成了Libevent的安裝。

安裝好Libevent以後，咱們就能繼續前進安裝Memcache了。

Memcache安裝

和安裝Libevent步驟相似，咱們仍是先下載memcache包，而後經過解壓、配置(./configure)、編譯 (make) 和安裝 (make install) 幾個步驟來安裝。

訪問memcache.org下載Memcache,  本文下載的版本是memcached-1.4.33.tar.gz

解壓縮

[root@dev18 memcached]# tar -zxvf memcached-1.4.33.tar.gz

./configure

進入解壓後的目錄，執行./configure

[root@dev18 memcached]# cd memcached-1.4.33
[root@dev18 memcached-1.4.33]# ./configure

問題及解決

安裝好Memcache以後，咱們來啓動Memcahce，

進入/usr/local/bin目錄，執行

memcached -d -m 10 -u root -p 11211 -P /temp/memcached.pid嘗試啓動Memcache

參數說明：

-d  表示啓動的是一個守護線程

-m RAM分配的數量，單位爲MB，由於執行小於64MB可能仍是會設置成64MB，因此本文就設置爲64

-u 指定運行Memcache的用戶

-p 執行Memcache監聽的端口

-P pid文件保存的地址

出現以下問題：

memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

[root@dev18 ~]# cd /usr/local/bin/
[root@dev18 bin]# memcached -d -m 64 -u root -p 11211 -P /temp/memcached.pid
memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory
[root@dev18 bin]#

首先來看一下，Memcahce是從哪裏找livevent-2.0.so.5的，使用LD_DEBUG=libs ./memcached -v命令查看。

[root@dev18 bin]# LD_DEBUG=libs ./memcached -v
      3668:	find library=libevent-2.0.so.5 [0]; searching
      3668:	 search cache=/etc/ld.so.cache
      3668:	 search path=/lib64/tls/x86_64:/lib64/tls:/lib64/x86_64:/lib64:/usr/lib64/tls/x86_64:/usr/lib64/tls:/usr/lib64/x86_64:/usr/lib64		(system search path)
      3668:	  trying file=/lib64/tls/x86_64/libevent-2.0.so.5
      3668:	  trying file=/lib64/tls/libevent-2.0.so.5
      3668:	  trying file=/lib64/x86_64/libevent-2.0.so.5
      3668:	  trying file=/lib64/libevent-2.0.so.5
      3668:	  trying file=/usr/lib64/tls/x86_64/libevent-2.0.so.5
      3668:	  trying file=/usr/lib64/tls/libevent-2.0.so.5
      3668:	  trying file=/usr/lib64/x86_64/libevent-2.0.so.5
      3668:	  trying file=/usr/lib64/libevent-2.0.so.5
      3668:	
./memcached: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory
[root@dev18 bin]#

從上面的結果能夠看出，Memcache會從/usr/lib64/下查找livevent-2.0.so.5。

接下來，看一下libevent的相關路徑信息，使用 whereis libevent來查找。

[root@dev18 bin]# whereis libevent
libevent: /usr/local/lib/libevent.so /usr/local/lib/libevent.la /usr/local/lib/libevent.a

從上面信息能夠看出，libevent是被安裝在/usr/local/lib/下了，這樣問題就找到了。

正是由於路徑不一致致使的問題：

libevent是被安裝在/usr/local/lib/下，

Memcache會從/usr/lib64/下查找livevent-2.0.so.5

明白了問題所在，解決的辦法就變得簡單了，建立一個軟連接便可。

ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5

從新嘗試啓動，沒有再報錯，

[root@dev18 bin]# ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
[root@dev18 bin]# memcached -d -m 64 -u root -p 11211 -P /temp/memcached.pid

使用ps -ef|grep memcached來查看Memcached相關進程，以下：

[root@dev18 bin]# ps -ef|grep memcached
root      3764     1  0 11:22 ?        00:00:00 memcached -d -m 10 -u root -p 11211 -P /temp/memcached.pid
root      3775  3580  0 11:23 pts/0    00:00:00 grep memcached
[root@dev18 bin]#

至此，Memcache的簡單安裝和啓動就完成了。
