最近又开始玩起了LiteSpeed,就把安装eaccelerator和XCache的方法跟大家简单分享一下吧。
其实这句话用“和”字不好,因为eAccelerator和XCache并不兼容,你只能忍痛割爱选择其一,但貌似eAccelerator对新版5.4的PHP支持不好,因此高版本的PHP,XCache算是更好的选择。
至于两者的具体对比,不在本文的涉及之列,大家可以自行网络搜索~在阅读本文前,强烈阅读本站关于LiteSpeed的相关教程,比如LiteSpeed的安装方法和面板的配置。
其实LiteSpeed在编译PHP的时候有这两个组件可选,但为什么要单独手动安装呢?
原因是官方的这两个组件勾选后经常出现无法解析等问题,这一问题和具体你使用的vps似乎无关,而和官网链接的时常抽风有关,因此,为了避免卡在Compile PHP的第一步,可以暂时取消这两个组件,像本文一样,手动安装~
无论安装哪一个,请先确保/usr/local/lsws/lsphp5/lib/php.ini是否存在,若不存在,执行如下命令
cp /usr/local/lsws/php/php.ini /usr/local/lsws/lsphp5/lib/
无论你选择安装哪一个,最后都请在LiteSpeed面板里Graceful Restart重启生效~
安装eAccelerator
1.安装必要的依赖文件(很多时候这一步其实是多此一举,但是为了避免出错,还是做吧~)
本文我以debian为例,至于centos,可以讲文中apt-get换成yum,基本可以通用~
apt-get install autoconf automake libtool m4
2.安装eAccelerator
可自行到官网查询最新版的下载链接,替换下面的url(前往官网下载页)
cd ~ wget https://github.com/downloads/eaccelerator/eaccelerator/eaccelerator-0.9.6.1.tar.bz2 tar jxvf eaccelerator-0.9.6.1.tar.bz2 cd eaccelerator-0.9.6.1 /usr/local/lsws/lsphp5/bin/phpize ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/lsws/lsphp5/bin/php-config make make install
如果你默认在LiteSpeed里编译的是PHP 5.4,进行make的时候可能出现如下错误,原因可能是新版对5.4的不兼容造成的。要么改装XCache,要么就换PHP 5.3吧
/home/package/eaccelerator-0.9.6.1/eaccelerator.c: In function ‘eaccelerator_restore’: /home/package/eaccelerator-0.9.6.1/eaccelerator.c:878: warning: assignment discards qualifiers from pointer target type /home/package/eaccelerator-0.9.6.1/eaccelerator.c: In function ‘eaccelerator_compile_file’: /home/package/eaccelerator-0.9.6.1/eaccelerator.c:1317: error: ‘zend_class_entry’ has no member named ‘line_start’ /home/package/eaccelerator-0.9.6.1/eaccelerator.c: At top level: /home/package/eaccelerator-0.9.6.1/eaccelerator.c:1913: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘eaccelerator_functions’ /home/package/eaccelerator-0.9.6.1/eaccelerator.c:1938: error: ‘eaccelerator_functions’ undeclared here (not in a function) make: *** [eaccelerator.lo] Error 1
3.配置eAccelerator生效(这一部分在前面的文章里讲过,这里不多说了~)
mkdir /usr/local/eaccelerator_cache chmod -R 777 /usr/local/eaccelerator_cache vi /usr/local/lsws/lsphp5/lib/php.ini
在php.ini文件末尾加入如下字段
[eaccelerator] zend_extension="/usr/local/lsws/lsphp5/lib/php/extensions/no-debug-non-zts-20090626/eaccelerator.so" eaccelerator.shm_size="1" eaccelerator.cache_dir="/usr/local/eaccelerator_cache" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="3600" eaccelerator.shm_prune_period="3600" eaccelerator.shm_only="0" eaccelerator.compress="1" eaccelerator.compress_level="9" eaccelerator.keys = "disk_only" eaccelerator.sessions = "disk_only" eaccelerator.content = "disk_only"
检测php.ini文件是否正常
/usr/local/lsws/lsphp5/bin/php -v
不出意外的话应该不会报错~
安装XCache
1.安装Xcache(查看官网最新版本)
cd ~ wget http://xcache.lighttpd.net/pub/Releases/3.0.0/xcache-3.0.0.tar.gz tar zxvf xcache-3.0.0.tar.gz cd xcache-3.0.0 /usr/local/lsws/lsphp5/bin/phpize ./configure --enable-xcache --with-php-config=/usr/local/lsws/lsphp5/bin/php-config make make install
make install后会给出一个目录,记下来备用,根据litespeed的版本不同,似乎这个目录名也不同~我的是/usr/local/lsws/lsphp5/lib/php/extensions/no-debug-non-zts-20100525/
2.修改php.ini文件
vi /usr/local/lsws/lsphp5/lib/php.ini
在末尾加入以下内容
extension_dir = "/usr/local/lsws/lsphp5/lib/php/extensions/no-debug-non-zts-20100525/" extension="xcache.so" [xcache-common] ;; install as zend extension (recommended), normally “$extension_dir/xcache.so” ;; or install as extension, make sure your extension_dir setting is correct ; extension = xcache.so [xcache.admin] xcache.admin.auth = On xcache.admin.user = "mOo" ; xcache.admin.pass = md5($your_password) xcache.admin.pass = [xcache] xcache.shm_scheme = "mmap" xcache.size = 32M xcache.count = 1 xcache.slots = 8K xcache.ttl = 3600 xcache.gc_interval = 300 ; Same as aboves but for variable cache ; If you don’t know for sure that you need this, you probably don’t xcache.var_size = 0M xcache.var_count = 1 xcache.var_slots = 8K xcache.var_ttl = 0 xcache.var_maxttl = 0 xcache.var_gc_interval = 300 ; N/A for /dev/zero xcache.readonly_protection = Off xcache.mmap_path = "/dev/zero" xcache.cacher = On xcache.stat = On
其中,密码字段xcache.admin.pass可自定义,用md5加密你要的密码填入,比如
echo -n "vmvps" | md5sum
3.检验php.ini是否出错
/usr/local/lsws/lsphp5/bin/php -v
如果出现如下错误
PHP Fatal error: Directive 'allow_call_time_pass_reference' is no longer available in PHP in Unknown on line 0
可以通过以下命令解决
perl -pi -e 's/^allow_call_time_pass_reference/;allow_call_time_pass_reference/' /usr/local/lsws/lsphp5/lib/php.ini
本文到此结束,还是那句话,无论你选择安装哪一个,最后都请在LiteSpeed面板里Graceful Restart重启生效~
