cd memcache-2.2.5//usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmakemake installcd ../tar jxvf eaccelerator-0.9.6.tar.bz2cd eaccelerator-0.9.6//usr/local/php/bin/phpize./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-configmakemake installcd ../tar zxvf PDO_MYSQL-1.0.2.tgzcd PDO_MYSQL-1.0.2//usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysqlmakemake installcd ../tar zxvf ImageMagick.tar.gzcd ImageMagick-6.5.1-2/./configuremakemake installcd ../tar zxvf imagick-2.3.0.tgzcd imagick-2.3.0//usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmakemake installcd ../
5. 修改php.ini文件
手工修改:查找/usr/local/php/etc/php.ini中的 extension_dir = "./"修改为extension_dir = "/usr/local/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
配置eAccelerator加速PHP:
mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/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:[eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"eaccelerator.shm_size="64"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"
6. 创建www用户和组,以及供www.carl.com虚拟主机使用的目录:
/usr/sbin/groupadd www
/usr/sbin/useradd -g www wwwmkdir -p /data0/htdocs/blogchmod +w /data0/htdocs/blogchown -R www:www /data0/htdocs/blog
7. 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/php/etc/目录中创建php-fpm.conf文件:
rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/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):

8. 启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
三、安装Nginx 0.8.34
1、 安装Nginx所需的pcre库:
tar zxvf pcre-8.01.tar.gz
cd pcre-8.01/./configuremake && make installcd ../2、 安装Nginx
tar zxvf nginx-0.8.34.tar.gz
cd nginx-0.8.34/./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_modulemake && make install
3、 创建Nginx配置文件
rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf输入以下内容:
user www www;
worker_processes 8;error_log /usr/local/nginx/logs/error.log crit;pid /usr/local/nginx/logs/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 65535;events { use epoll; worker_connections 65535;}http { include mime.types; default_type application/octet-stream; #charset gb2312; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on; #limit_zone crawler $binary_remote_addr 10m; server { listen 80; server_name www.carl.com; index index.html index.htm index.php; root /data0/htdocs/blog; #limit_conn crawler 20; location ~ .*\.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 1h; } log_format access '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; access_log /usr/local/nginx/logs/carl_access.log access; } server { listen 80; server_name status.blog.s135.com; location / { stub_status on; access_log off; } }}
在/usr/local/nginx/conf/目录中创建fcgi.conf文件:
vi /usr/local/nginx/conf/fcgi.conf
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-redirectfastcgi_param REDIRECT_STATUS 200;
4、 启动Nginx
ulimit -SHn 65535
/usr/local/nginx/sbin/nginx四、配置开机自动启动Nginx + PHP
vi /etc/rc.local
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start/usr/local/nginx/sbin/nginx五、优化Linux内核参数
vi /etc/sysctl.conf
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768net.core.somaxconn = 32768net.core.wmem_default = 8388608net.core.rmem_default = 8388608net.core.rmem_max = 16777216net.core.wmem_max = 16777216net.ipv4.tcp_timestamps = 0net.ipv4.tcp_synack_retries = 2net.ipv4.tcp_syn_retries = 2net.ipv4.tcp_tw_recycle = 1#net.ipv4.tcp_tw_len = 1net.ipv4.tcp_tw_reuse = 1net.ipv4.tcp_mem = 94500000 915000000 927000000net.ipv4.tcp_max_orphans = 3276800#net.ipv4.tcp_fin_timeout = 30#net.ipv4.tcp_keepalive_time = 120net.ipv4.ip_local_port_range = 1024 65535
/sbin/sysctl –p 使新添加的内核参数生效!
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、平滑重启: ①、对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:/usr/local/nginx/sbin/nginx -s reload
②、对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。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.shvi /usr/local/nginx/sbin/cut_nginx_log.sh
输入 以下内容:
#!/bin/bash
# This script run at 00:00# The Nginx logs pathlogs_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").logkill -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:
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh
