感觉很久没发VPS教程类的文章了，正好最近又开始玩起了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，但为什么微魔要单独手动安装呢？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 m42.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:1938: error: ‘eaccelerator_functions’ undeclared here (not in a function)
make: *** [eaccelerator.lo] Error
13.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~
