——————————————————————————–

2、编译安装MySQL 5.0.46

#/usr/sbin/groupadd mysql
#/usr/sbin/useradd -g mysql mysql
#tar zxvf mysql-5.0.46.tar.gz
#cd mysql-5.0.46
#./configure –prefix=/usr/local/mysql/ –with-unix-socket-path=/tmp/mysql.sock –without-debug –with-client-ldflags=-all-static –with-mysqld-ldflags=-all-static

–enable-assembler –with-extra-charsets=gbk,gb2312,utf8 –with-pthread –enable-thread-safe-client

#make

#make install

#cp support-files/my-medium.cnf /etc/my.cnf

#cd /usr/local/mysql

(1). 以mysql用户帐号的身份建立数据表：

#bin/mysql_install_db defaults-file=/etc/my.cnf –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data –user=mysql –pid-file=/usr/local/mysql/mysql.pid –skip-locking –port=3306 –socket=/tmp/mysql.sock

#chown -R mysql:mysql /usr/local/mysql

(2).启动MySQL

#bin/mysqld_safe –user=mysql &

3.编译安装PHP-5.2.6

#export LD_PRELOAD=/usr/local/lib/preloadable_libiconv.so

#cd /share/nginx-php/php-5.2.6

#./configure –prefix=/usr/local/php –with-mysql=/usr/local/mysql/ –with-iconv=/usr/local/libiconv/lib

–with-libxml-dir –enable-xml –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –enable-fastcgi –with-mcrypt

#Make

#Make install

#cp php.ini-dist /usr/local/lib/php.ini

4、编译安装PHP5扩展模块

#/usr/local/php/bin/phpize
#./configure –with-jpeg-dir –with-png-dir –with-zlib-dir –with-ttf –with-freetype-dir –with-php-config=/usr/local/php/bin/php-config
#make
#make install

5、修改php.ini文件
查找/usr/local /php/etc/php.ini中的extension_dir = “./”
修改为extension_dir=”/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/”
并在此行后增加以下几行，然后保存：
　extension = “memcache.so”
　extension = “gd.so”

6.创建www用户和组，以及其使用的目录：

#/usr/sbin/groupadd www -g 48
#/usr/sbin/useradd -u 48 -g www www
#mkdir -p / share/htdocs
#chmod +w /share/htdocs
#chown -R www:www vshare/htdocs

7、安装lighttpd中附带的spawn-fcgi，用来启动php-cgi
　　注：压缩包中的spawn-fcgi程序为已经编译成二进制的版本。

#cd /nginx/php/

#cp spawn-fcgi /usr/local/php/bin
#chmod +x /usr/local/php/bin/spawn-fcgi

8、启动php-cgi进程，监听127.0.0.1的10080端口，进程数为64（如果服务器内存小于3GB，可以只开启25个进程），用户为www,组为www：

#/usr/local/php/bin/spawn-fcgi -f /usr/local/php/bin/php-cgi -a 127.0.0.1 -p 10080 -C 25 -u www -g www

三、安装Nginx 0.5.33

#tar zxvf pcre-7.2.tar.gz
#cd pcre-7.2/
#./configure
#make && make install

2、安装Nginx

#tar zxvf nginx-0.7.21.tar.gz
#cd nginx-0.7.21/
#./configure –user=www –group=www –prefix=/usr/local/webserver/nginx –with-http_stub_status_module
#make && make install

3.创建Nginx日志目录

#mkdir -p /share/logs

#chmod +w /share/logs
#chown -R www:www /share/logs

4.修改Nginx配置文件

location ~ \.php$ {

include fast-cgi.conf;

}

}

四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

在末尾增加以下内容：

引用

ulimit -SHn 51200
/usr/local/php/bin/spawn-fcgi -f /usr/local/r/php/bin/php-cgi -a 127.0.0.1 -p 10080 -C 64 -u www –u www
/usr/local//nginx/sbin/nginx -c /usr/local /nginx/conf/nginx.conf

五、优化Linux内核参数

vi /etc/sysctl.conf

在末尾增加以下内容：

引用

net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000 65000

六、在不停止Nginx服务的情况下平滑变更Nginx配置
(1)修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：

/usr/local/nginx/sbin/nginx –t

　如果屏幕显示以下两行信息，说明配置文件正确：
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
(2)输入以下命令查看Nginx主进程号：

ps -ef | grep “nginx: master process” | grep -v “grep” | awk -F ‘ ‘ ‘{print $2}’
　 屏幕显示的即为Nginx主进程号，例如：
　　6302
　　这时，执行以下命令即可使修改过的Nginx配置文件生效：

kill -HUP 6302

3.重启php-cgi和nginx

(1)停止php-cgi和nginx：

killall php-cgi

kill -HUP `cat /var/run/nginx`

(2)启动php-cgi和nginx

/usr/local/php/bin/spawn-fcgi -f /usr/local/php/bin/php-cgi -a 127.0.0.1 -p 10080 -C 64 -u www –u www
/usr/local/nginx/sbin/nginx -c /usr/local /nginx/conf/nginx.conf

4.测试：

# vi /share/htdocs/index.php

IE地址栏: http://192.168.30.81/vhost/install/index.php

———————————————————-

七．安装Discuz论坛

1. UCenter、UCenter Home、Discuz! 集成安装包下载：

http://download.comsenz.com/UC_UCH_DZ/UC_UCH_DZ_SC_GBK.zip

将压缩包解压后的upload目录中的文件上传到服务器的/share/htdocs/vhost目录

2.安装配置

1.mysql数据库配置

(1)在mysql中创建一个论坛数据库discuz:

Mysql>create database discuz;

Mysql>use discuz;

Mysql>source /share/htdocs/vhost/bbs/install/discuz.sql; // 将discuz.sql导入,创建论坛

Mysql>grant create,drop,select,insert,update,delete on discuz.* to admin@localhost identified by “admin”; // 给discuz数据库创建一个用户

(2)配置/share/htdocs/vhost/bbs/config.in.php文件里的相关信息，

$dbhost = ‘localhost’; // 数据库服务器

$dbuser = ‘admin’; // 数据库用户名

$dbpw = ‘admin’; // 数据库密码

$dbname = ‘discuz’;

2.在浏览器中访问: http://192.168.30.81/vhost/install/index.php

3. 请根据向导，填入必要的信息，开始安装。
特别注意的是，要根据安装向导的提示，正确设置各个目录的读写属性。

4. 安装完毕后，为了数据安全，请务必将 install 目录删除。

5.安装完毕，拷贝以下信息：

UCenter的访问网址:

http://192.168.30.81/vhost/ucenter

UCenter 创始人密码:admin

DISCUZ!的访问网址:

http://192.168.30.81/vhost/bbs
