安裝xcache

前提php、php-fpm、mariadb等LAMP環境已經架設好

1、安裝xcache

cd /usr/local/src #進入軟件包存放目錄

wget http://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz#下載

tar zxvf xcache-3.2.0.tar.gz #解壓

cd xcache-3.2.0 #進入安裝目錄

/usr/bin/phpize #用phpize生成configure配置文件---------這里的目錄，用which phpize來找

[root@lgq bin]# ln -sv phpize /usr/src/xcache-3.2.0

‘/usr/src/xcache-3.2.0/phpize’ -> ‘phpize

[root@lgq xcache-3.2.0]# phpize

Configuring for:

PHP Api Version:         20100412

Zend Module Api No:      20100525

Zend Extension Api No:   220100525

[root@lgq xcache-3.2.0]#./configure --enable-xcache--enable-xcache-coverager --enable-xcache-optimizer --with-php-config=/usr/bin/php-config #配置

make #編譯

make install #安裝

安裝完成之后，出現下面的界面，記住以下路徑，后面會用到。/usr/lib64/php/modules/

/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/#xcache模塊路徑

2、創建xcache緩存文件

touch /tmp/xcache #創建文件

chmod 777 /tmp/xcache #設置權限

3、創建xcache管理員密碼為123456

echo -n "123456" | md5sum #記住類似下面一行代碼（md5加密之后的密碼），后面會用到

c1820eeffb72ef4463aa2a67c65c7b0a

4、拷貝xcache后臺管理程序到網站根目錄

cp -r /usr/local/src/xcache-3.2.0/htdocs  /var/www/html/xcache

chown apache.apache -R /var/www/html/xcache #設置xcache目錄和網站目錄權限相同

5、配置php支持xcache

vi /usr/local/php/etc/php.ini #編輯配置文件，在最后一行添加以下內容

[xcache-common]

extension = xcache.so

[xcache.admin]

xcache.admin.enable_auth = On

xcache.admin.user = "xcache"

xcache.admin.pass = "c1820eeffb72ef4463aa2a67c65c7b0a"

[xcache]

xcache.shm_scheme ="mmap"

xcache.size=60M

xcache.count =1

xcache.slots =8K

xcache.ttl=0

xcache.gc_interval =0

xcache.var_size=64M

xcache.var_count =1

xcache.var_slots =8K

xcache.var_ttl=0

xcache.var_maxttl=0

xcache.var_gc_interval =300

xcache.test =Off

xcache.readonly_protection = On

xcache.mmap_path ="/tmp/xcache"

xcache.coredump_directory =""

xcache.cacher =On

xcache.stat=On

xcache.optimizer =Off

[xcache.coverager]

xcache.coverager =On

xcache.coveragedump_directory =""

:wq!   #保存退出

6、測試

service php-fpm restart#重啟php-fpm

service nginx restart #重啟nginx

瀏覽器打開網站根目錄下面的xcache

輸入用戶名xcache 密碼123456

可以看到如下界面

Warning: phpinfo(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /var/www/html/xcache/cacher/index.phpon line 126Warning: phpinfo(): It is not safe to rely on the system's timezone settings.

是因為時區的問題引起的

vim /etc/php.ini 去掉date.timezone前面的;號，后面上 Asia/Shanghai，就不會再提示錯誤信息了

date.timezone =Asia/Shanghai
