2019獨角獸企業(yè)重金招聘Python工程師標(biāo)準(zhǔn)>>>

1. 用戶、組創(chuàng)建

• groupadd memcache 創(chuàng)建組
• cat /etc/passwd|grep memcache 查看用戶是否創(chuàng)建
• useradd -d /usr/memcache -g memcache -m memcache 創(chuàng)建用戶

2. 下載

• wget http://www.danga.com/memcached/dist/memcached-1.2.2.tar.gz 下載Memcache
• wget --no-check-certificate http://www.monkey.org/~provos/libevent-1.3.tar.gz 下載依賴libevent 官網(wǎng)：http://www.monkey.org/~provos/libevent/

3. 解壓

• tar -zxvf libevent-1.3.tar.gz
• tar -zxvf memcached-1.2.2.tar.gz

4. 安裝libevent

./configure --prefix=/usr

[root@CentOSv64x64 libevent-1.3]# make

[root@CentOSv64x64 libevent-1.3]# make install

5. 安裝Memcache

./configure --with-libevent=/usr

[root@CentOSv64x64 memcached-1.2.2]# make

[root@CentOSv64x64 memcached-1.2.2]# make install

[root@CentOSv64x64 memcached-1.2.2]# make install Making install in doc make[1]: Entering directory `/usr/memcache/install/memcached-1.2.2/doc' make[2]: Entering directory `/usr/memcache/install/memcached-1.2.2/doc' make[2]: Nothing to be done for `install-exec-am'. /bin/sh ../mkinstalldirs /usr/local/man/man1 mkdir -p -- /usr/local/man/man1/usr/bin/install -c -m 644 ./memcached.1 /usr/local/man/man1/memcached.1 make[2]: Leaving directory `/usr/memcache/install/memcached-1.2.2/doc' make[1]: Leaving directory `/usr/memcache/install/memcached-1.2.2/doc' make[1]: Entering directory `/usr/memcache/install/memcached-1.2.2' make[2]: Entering directory `/usr/memcache/install/memcached-1.2.2' /bin/sh ./mkinstalldirs /usr/local/bin/usr/bin/install -c memcached /usr/local/bin/memcached/usr/bin/install -c memcached-debug /usr/local/bin/memcached-debug make[2]: Nothing to be done for `install-data-am'. make[2]: Leaving directory `/usr/memcache/install/memcached-1.2.2' make[1]: Leaving directory `/usr/memcache/install/memcached-1.2.2'

5.啟動Memcached服務(wù)器

/usr/local/bin/memcached -d -m 50 -u root -l 192.168.8.105 -p 12000 -c 256 -P /tmp/memcached.pid

• -d選項是啟動一個守護(hù)進(jìn)程
• -m是分配給Memcache使用的內(nèi)存數(shù)量，單位是MB，這里是10MB
• -u是運行Memcache的用戶，我這里是root
• -l是監(jiān)聽的服務(wù)器IP地址，如果有多個地址的話，這里指定了服務(wù)器的IP地址192.168.8.105
• -p是設(shè)置Memcache監(jiān)聽的端口，我這里設(shè)置了12000，最好是1024以上的端口
• -c選項是最大運行的并發(fā)連接數(shù)，默認(rèn)是1024，我這里設(shè)置了256，按照你服務(wù)器的負(fù)載量來設(shè)定
• -P是設(shè)置保存Memcache的pid文件，我這里是保存在 /tmp/memcached.pid

執(zhí)行報錯：

[root@CentOSv64x64 memcached-1.2.2]# /usr/local/bin/memcached -d -m 50 -u root -l 192.168.8.105 -p 12000 -c 256 -P /tmp/memcached.pid /usr/local/bin/memcached: error while loading shared libraries: libevent-1.3.so.1: cannot open shared object file: No such file or directory

解決方法：[root@CentOSv64x64 lib]# ln -s /usr/lib/libevent-1.3.so.1 /usr/lib64/libevent-1.3.so.1 _ 3. ps -aux|grep memcached 查看Memcached是否啟動 4. 關(guān)閉進(jìn)程 _ kill cat /tmp/memcached.pid

6.開機自啟動

• 在/etc/rc.d/rc.local文件中追加：
• /usr/local/memcached/bin/memcached -d -m 10 -p 12000 -u memcache -c 256 加起-u 不用ROOT用戶啟動

6. 測試Memcached

[root@CentOSv64x64 ~]# telnet 192.168.8.105 12000 Trying 192.168.8.105... Connected to 192.168.8.105. Escape character is '^]'. set key1 0 60 4 zhou STORED get key1 VALUE key1 0 4 zhou END

未安裝telnet:yum install telnet
