禁用 SSH V1 协议:找到#Protocol 2,1改为：Protocol 2
禁用服务器端GSSAPI找到以下两行，并将它们注释：
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
禁用 DNS 名称解析
找到：#UseDNS yeas改为：UseDNS no
禁用客户端 GSSAPI
找到：GSSAPIAuthentication yes 将这行注释掉。
最后，确认修改正确后重新启动 SSH 服务
# service sshd restart
# ssh -v 确认 OpenSSH 以及 OpenSSL 版本正确。

修改php.ini文件
手工修改：查找/usr/local/webserver/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 = “pdo_mysql.so”
extension = “imagick.so”
再查找output_buffering = Off
修改为output_buffering = On
自动修改：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改：
sed -i ‘s#extension_dir = “./”#extension_dir = “/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/”nextension = “memcache.so”nextension = “pdo_mysql.so”nextension = “imagick.so”n#’ /usr/local/webserver/php/etc/php.ini
sed -i ‘s#output_buffering = Off#output_buffering = On#’ /usr/local/webserver/php/etc/php.ini
6、配置eAccelerator加速PHP：
mkdir -p /usr/local/webserver/eaccelerator_cache
vi /usr/local/webserver/php/etc/php.ini
按shift+g键跳到配置文件的最末尾，加上以下配置信息：
引用
[eaccelerator]
zend_extension=”/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so”
eaccelerator.shm_size=”128″
eaccelerator.cache_dir=”/usr/local/webserver/eaccelerator_cache”
eaccelerator.enable=”1″
eaccelerator.optimizer=”1″
eaccelerator.check_mtime=”1″
eaccelerator.debug=”0″
eaccelerator.filter=””
eaccelerator.shm_max=”0″
eaccelerator.shm_ttl=”300″
eaccelerator.shm_prune_period=”120″
eaccelerator.shm_only=”0″
eaccelerator.compress=”1″
eaccelerator.compress_level=”9″
修改配置文件：
vi /etc/sysctl.conf
输入以下内容：
引用
kernel.shmmax = 134217728
然后执行以下命令使配置生效：
/sbin/sysctl -p

创建www用户和组，以及供两个虚拟主机使用的目录：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /var/www/blog
chmod +w /var/www//blog
chown -R www:www /var/www/blog
mkdir -p /var/www/www
chmod +w /var/www/www
chown -R www:www /var/www/www
创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：
cd /usr/local/webserver/php/etc/
cp php-fpm.conf php-fpm.confb
rm -f /usr/local/webserver/php/etc/php-fpm.conf
vi /usr/local/webserver/php/etc/php-fpm.conf
输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name=”display_errors”>0</value>改为<value name=”display_errors”>1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：

三、安装Nginx 0.7.54
1、安装Nginx所需的pcre库：
tar zxvf pcre-7.8.tar.gz
cd pcre-7.8/
./configure
make && make install
cd ../
2、安装Nginx
tar zxvf nginx-0.7.54.tar.gz
cd nginx-0.7.54/
./configure –user=ftp –group=ftp –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module –with-http_realip_module –with-http_addition_module –with-http_sub_module –with-http_dav_module –with-http_flv_module –with-openssl=/home/zhy1899/nginx/openssl-0.9.8k
make && make install
cd ../
3、创建Nginx日志目录
mkdir -p /var/nginx/logs
chmod +w /var/nginx/logs
chown -R www:www /var/nginx/logs
4、创建Nginx配置文件
①、在/usr/local/nginx/conf/目录中创建nginx.conf文件：
cd /usr/local/nginx/conf/
cp nginx.conf nginx.confb
rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf
输入以下内容：
引用
user www www;
worker_processes 8;
error_log /var/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;

fastcgi_index index.php;
include fcgi.conf;
}

}
log_format access ‘$remote_addr – $remote_user [$time_local] “$request” ‘

location ~ .*.(php|php5)?$
{

fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
log_format wwwlogs ‘$remote_addr – $remote_user [$time_local] “$request” ‘

}
server
{
listen 82;
server_name 192.168.6.253;
location / {
stub_status on;
access_log off;
}
}
}
②、在/usr/local/nginx/conf/目录中创建fcgi.conf文件：
vi /usr/local/nginx/conf/fcgi.conf
输入以下内容：
引用
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with –enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
5、启动Nginx
ulimit -SHn 51200
/usr/local/nginx/sbin/nginx
ZendOptimizer]
tar zxvf ZendOptimizer-3.3.0a-linux-glibc21-i386.tar.gz
cd ZendOptimizer-3.3.0a-linux-glibc21-i386
./install.sh
文字图形界面－同意安装协议－选择Zend安装目录－选择php.ini所在目录－不使用apache web server－installing－finished
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/webserver/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx
——————————————————————————–
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
使配置立即生效：
/sbin/sysctl -p
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、这时，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
或者无需这么麻烦，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/nginx/nginx.pid`
七、编写每天定时切割Nginx日志的脚本
1、创建脚本/usr/local/nginx/sbin/cut_nginx_log.sh
vi /usr/local/nginx/sbin/cut_nginx_log.sh
输入以下内容：
引用
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path=”/usr/local/nginx/logs/”
mkdir -p ${logs_path}$(date -d “yesterday” +”%Y”)/$(date -d “yesterday” +”%m”)/
mv ${logs_path}access.log ${logs_path}$(date -d “yesterday” +”%Y”)/$(date -d “yesterday” +”%m”)/access_$(date -d “yesterday” +”%Y%m%d”).log
kill -USR1 `cat /usr/local/nginx/nginx.pid`
2、设置crontab，每天凌晨00:00切割nginx访问日志
crontab -e
输入以下内容：
引用
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh
