nginx+lighttpd+memcache+mysql配置与调试
搭建环境
虚拟机:VMware-workstation-full-8.0.3-703057.zip
linux版本：CentOS-5.4-i386-bin-DVD.iso
一，VM,CentOS安装
略....
二，centos基本配置
1,安装vim
yum -y install vim-enhanced
2,配置vim显示行号
如果是用的普通用户的话在home目录下建一个.vimrc文件（记着，原来没有，要新创一个文件）里
面加一行setnu如果你想对所有用户都这样，那么在/etc/vimrc文件中加入这一行。/etc/vimrc是所有用户
启动vim时都会执行的。每个用户的home目录下的.vimrc是这个用户启动vim时会执行的
3,升级firefox,参见http://blog.chinaunix.net/uid-22414998-id-3033200.html
4,解决firefox中文乱码
a.下载两个rpm包 fonts-chinese-3.02-9.6.e15.noarch.rpm
fonts-ISO8859-2-75dpi-1.0-17.1.noarch.rpm 然后安装rmp rpm -zxf "xxx.rpm" 或yum install
xxx.rpm 设置forefox:语言(中国) 然后重起计算机运行 fc-cache -fv清除下cache,这样firefox就可以显
示中文了
b.vi /etc/sysconfig/i18n配置
LANG="en_US.UTF-8"
SUPPORTED="zh_CN.UTF-8:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"
三,安装mysql
[root@localhost]# yum install mysql mysql-server
[root@localhost]# service mysqld restart
[root@localhost]# chkconfig --level 3 mysqld on
[root@localhost]# mysqladmin -u root password root
[root@localhost]# netstat -alp | grep 'mysql'
四，安装lighttpd
[root@localhost]# wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-
1.el5.rf.i386.rpm
[root@localhost]# rpm -ivh rpmforge-release-0.5.1-1.el5.rf.i386.rpm
[root@localhost]# yum install lighttpd
[root@localhost]# chkconfig --level 3 lighttpd on
[root@localhost]# /etc/init.d/lighttpd start
[root@localhost]# chown lighttpd:lighttpd /var/log/lighttpd
五，安装PHP5（fastcgi）
[root@localhost]# yum install lighttpd-fastcgi php-cli
六,配置lighttpd与PHP
1,修改默认端口为8080，把80端口给nginx
vi /etc/lighttpd/lighttpd.conf修改
server.port = 8080
2,vi /etc/lighttpd/modules.conf修改
server.modules = (
"mod_access",
"mod_alias",
# "mod_auth",
# "mod_evasive",
# "mod_redirect",
"mod_rewrite",
# "mod_setenv",
# "mod_usertrack",
)
开启相关模块
alias.url = ( "/phpmyadmin" => "/usr/share/phpmyadmin") #配置phpmyadmin
include "conf.d/fastcgi.conf" #打开fastcgi配置
####配置虚拟主机
在/var/www/中建三个PHP项目,project1,project2,project3,分别输出
vim index.php
echo "this is project x";
####多域名配置多个项目
$HTTP["host"] == "www.project1.com" {
server.name = "www.project1.com"
server.document-root = "/var/www/project1"
server.errorlog = "/var/www/project1/error.log"
accesslog.filename = "/var/www/project1/access.log"
}
else $HTTP["host"] == "www.project2.com" {
server.name = "www.project2.com"
server.document-root = "/var/www/project2"
server.errorlog = "/var/www/project2/error.log"
accesslog.filename = "/var/www/project2/access.log"
}
else $HTTP["host"] == "www.project3.com" {
server.name = "www.project3.com"
server.document-root = "/var/www/project3"
server.errorlog = "/var/www/project3/error.log"
accesslog.filename = "/var/www/project3/access.log"
}
####多端口配置
$SERVER["socket"] == ":8001" {
server.document-root = "/var/www/project1"
}
else $SERVER["socket"] == ":8002" {
server.document-root = "/var/www/project2"
}
else $SERVER["socket"] == ":8003" {
server.document-root = "/var/www/project3"
}
3,fastcgi配置
vi /etc/lighttpd/conf.d/fastcgi.conf
填加如下内容
fastcgi.server = ( ".php" =>
( "localhost" =>
(
"socket" => "/tmp/php-fastcgi.socket",
"bin-path" => "/usr/bin/php-cgi",
)
)
)
4,配置PHP
vim /etc/php.ini
#增加如下两行：
cgi.fix_pathinfo = 1
extension=mysql.so #用于phpmyadmin来管理mysql数据库
[root@localhost]# chown lighttpd:lighttpd /var/lib/php/session
#因为修改了lighttpd.conf配置文件，所以得重新启动服务
[root@localhost]# service lighttpd restart
5,重启lighttpd
service lighttpd restart 重启报错
Starting lighttpd: 2012-05-22 22:21:52: (server.c.722)couldn't set 'max filedescriptors'
Operation not permitted
先执行setenforce 0 临时关闭selinux
(修改selinux:vi /etc/selinux/config)
重新启动成功
6,测试
访问
http://localhost:8080输出phpinfo信息，成功
分别访问
http://localhost:8001
http://localhost:8002
http://localhost:8003
得到正确显示分别为
this is project 1
this is project 2
this is project 3
七,让PHP支持MYSQL模块
#查看有哪些PHP支持且可安装的模块
[root@localhost]# yum search php | grep '^php'
[root@localhost]# yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear
php-xml php-xmlrpc php-tidy php-snmp php-mhash php-mcrypt php-mbstring
[root@localhost]# service lighttpd restart
八,安装phpmyadmin与配置
(1),安装phpmyadmin
[root@localhost]# yum install phpmyadmin
注意：使用phpmyadmin的RPM包软件时，默认是安装在/usr/share目录下
(2)、配置phpmyadmin
[root@localhost]# cd /usr/share/phpmyadmin
[root@example phpmyadmin]# cp config.sample.inc.php config.inc.php
[root@example phpmyadmin]# vi config.inc.php
$cfg['Servers'][$i]['auth_type'] = 'http'; #把cookie方式改为http方式即可
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
$cfg['Servers'][$i]['extension'] = 'mysql';
(3),测试，访问http://127.0.0.1:8080/phpmyadmin登录成功
九，安装memcache服务
1.分别把memcached和libevent下载回来，放到 /tmp 目录下：
# cd /tmp
# wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz
2.先安装libevent：
# tar zxvf libevent-1.2.tar.gz
# cd libevent-1.2
# ./configure --prefix=/usr
# make
# make install
3.测试libevent是否安装成功：
# ls -al /usr/lib | grep libevent
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3
-rwxr-xr-x 1 root root 263546 11?? 12 17:38 libevent-1.2.so.1.0.3
-rw-r--r-- 1 root root 454156 11?? 12 17:38 libevent.a
-rwxr-xr-x 1 root root 811 11?? 12 17:38 libevent.la
lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent.so -> libevent-1.2.so.1.0.3
还不错，都安装上了。
4.安装memcached，同时需要安装中指定libevent的安装位置：
# cd /tmp
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure --with-libevent=/usr
# make
# make install
如果中间出现报错，请仔细检查错误信息，按照错误信息来配置或者增加相应的库或者路径。
安装完成后会把memcached放到 /usr/local/bin/memcached ，
5.测试是否成功安装memcached：
# ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug
6,安装php memcache扩展
先安装php的扩展：yum -y install php-devel
再安装memcache的php扩展：pecl install memcache
7,启动memcached
memcached -d -u root -m 64 -c 1024
8,测试,在默认根目录/srv/www/lighttpd/index.php中加入
echo "test memcache...";
$mem = new Memcache;
$mem->connect("127.0.0.1", 11211);
$mem->set("key", "This is a test!", 0, 60);
$val = $mem->get("key");
echo $val;
访问localhost:8080
输出test memcache...This is a test!
十,安装nginx，配置负载匀衡
1, nginx安装略....
2,nginx配置
vim nginx.conf
