本帖最后由 yuanzhichen 于 2011-12-06 11:29 编辑

自己来回答吧
/usr/local/webserver/mysql/include/mysql/my_sys.h:1027:27: error: mysql/psi/psi.h: No such file or directory

这个貌似mysql中的目录是 mysql/psi.h
目录中调整为mysql/psi/psi.h就可以了

/usr/local/webserver/mysql/include/mysql/m_string.h:285:26: error: mysql/plugin.h: No such file or directory

参照
以下方法
echo “/usr/local/webserver/mysql/lib/mysql” >> /etc/ld.so.conf
ldconfig

ln -s /usr/local/webserver/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/webserver/mysql/include/mysql /usr/include/mysql

安装完成以后复制 cp /data/software/php-5.3.8/php.ini.product   /usr/local/php/etc/4、编译安装PHP5扩展模块tar zxvf memcache-2.2.5.tgzcd memcache-2.2.5//usr/local/webserver/php/bin/phpize./configure --with-php-config=/usr/local/webserver/php/bin/php-configmakemake installcd ../tar jxvf eaccelerator-0.9.6.1.tar.bz2cd eaccelerator-0.9.6.1//usr/local/webserver/php/bin/phpize./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-configmakemake installcd ../tar zxvf PDO_MYSQL-1.0.2.tgzcd PDO_MYSQL-1.0.2//usr/local/webserver/php/bin/phpize./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/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/webserver/php/bin/phpize./configure --with-php-config=/usr/local/webserver/php/bin/php-configmakemake installcd ../

memcached 配置：
http://blog.sina.com.cn/s/blog_66ac09390101drxc.html
服务器密码：7db25558

1/安装libmemcached

Centos及 Aliyun Linux 5系列版本 【64位版本】
首先需要确认是否安装了gcc-c++等组件如没有请执行
yum install gcc+ gcc-c++
1) rpm –qa | grep php 查看系统中Z3nTeiKw3P是否有PHP环境，如果没有则安装之；如果有PHP则不要安装！建议使用php5.3【含】以上版本PHP5.2部分版本系列源代码会有zend_parse_parameters_none函数会出错，如需使用请参照php官方相关文档【包含源码编译的PHP】
yum install php53 php53-devel
2) 安装SASL相关环境yum install cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel cyrus-sasl-lib
3) 安装源码包libmemcached 【推荐版本libmemcached1.0.2】
请先检测下是否有已安装了这些包【包含源码包】如有则不需要安装

wget http://launchpad.net/libmemcached/1.0/1.0.2/download/libmemcached-1.0.2.tar.gz
tar -zxvf libmemcached-1.0.2.tar.gz
cd libmemcached-1.0.2
./configure –prefix=/usr/local/libmemcached –enable-sasl
make
make install
cd ..／

2、安装memcached

4) 安装源码包memcached 【推荐版本memcached2.0】
安装MEMCACHED前需要确认是否有zlib-devel包没有需要执行
yum install zlib-devel

请先检测下是否有已安装了memcached客户端包【包含源码包】如有则不需要安装，但需要重新编译增加-enable-memcached-sasl这个扩展

wget http://pecl.php.net/get/memcached-2.0.0.tgz
tar -zxvf memcached-2.0.0.tgz
cd memcached-2.0.0
/usr/local/webserver/php/bin/phpize（如果系统中有两套PHP环境，需绝对路径调用该命令/usr/bin/phpize，该路径为使用OCS的PHP环境路径，请在memcached源码目录内执行phpize）
./configure –with-memcached –with-php-config=/usr/local/webserver/php/bin/php-config
–with-libmemcached-dir=/usr/local/libmemcached –enable-memcached-sasl
make
make install
最后修改php.ini文件（locate找该文件，yum安装的一般在/etc/php.ini 如果系统中有两套PHP环境，需找到使用OCS的PHP环境路径，对应修改之），增加extension=”memcached.so”
执行php –m |grep memcached 如显结果有 memcache 表示环境已支持memcache
使用该页面最后的测试代码测试下是否环境部署成功，请修改代码中相应的地址 端口 用户名及密码

5、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-20090626/"　　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　　再查找; cgi.fix_pathinfo=0　　修改为cgi.fix_pathinfo=0，防止Nginx文件类型错误解析漏洞。　　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.inised -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.inised -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.inised -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini6、配置eAccelerator加速PHP：mkdir -p /usr/local/webserver/eaccelerator_cachevi /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="64"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="3600"eaccelerator.shm_prune_period="3600"eaccelerator.shm_only="0"eaccelerator.compress="1"eaccelerator.compress_level="9"　　创建www用户和组，以及供blog.s135.com和www.s135.com两个虚拟主机使用的目录：    /usr/sbin/groupadd www    /usr/sbin/useradd -g www www    mkdir -p /data0/htdocs/blog    chmod +w /data0/htdocs/blog    chown -R www:www /data0/htdocs/blog    mkdir -p /data0/htdocs/www    chmod +w /data0/htdocs/www    chown -R www:www /data0/htdocs/www　　8、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.inivi /usr/local/webserver/php/etc/php-fpm.conf配置而无需重启php-cgi）：启动php-fpm /usr/local/webserver/php/sbin/php-fpm -c /usr/local/webserver/php/etc/php-fpm.conf

启动错误解决:
ALERT: [pool www] pm.min_spare_servers(0) must be a positive value
编辑php-fpm.conf找到pm.min_spare_servers 去除;号,注意非注释内容pm.min_spare_servers
ALERT: [pool www] pm.max_spare_servers(0) must be a positive value
编辑php-fpm.conf找到pm.max_spare_servers 去除;号,同样非注释内容pm.max_spare_servers
WARNING: [pool www] pm.start_servers is not set. It’s been set to 20.
编辑php-fpm.conf找到pm.start_servers 去除;号,同样非注释内容pm.start_servers
ERROR: bind() for address ‘127.0.0.1:9000’ failed: Address already in use (98)

启动 php-fpm:

—————-补充内容php 5.3.8 中 php-fpm 配置 成 服务启动—————-

cp -f /data0/software/php-5.3.6/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
php-fpm的启动：

vim /usr/local/webserver/php/etc/php-fpm.conf

php-fpm.pid 目录必须是：/usr/local/webserver/php/var/run/php-fpm.pid

chmod 755 /etc/init.d/php-fpm
/etc/init.d/php-fpm start
/sbin/chkconfig –add php-fpm (添加到开机服务列表)
/sbin/chkconfig php-fpm on

php-fpm的启动、停止和重启：
/etc/init.d/php-fpm start
/etc/init.d/php-fpm stop

/etc/init.d/php-fpm reload

9、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/webserver/php/sbin/php-fpm start注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。

三、安装Nginx 1.0.9.tar.gz

1、安装Nginx所需的pcre库：tar zxvf pcre-8.10.tar.gzcd pcre-8.10/./configuremake && make installcd ../2、安装Nginxtar zxvf nginx-1.0.9.tar.gzcd nginx-1.0.9/./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_modulemake && make installcd ../3、创建Nginx日志目录mkdir -p /data1/logschmod +w /data1/logschown -R www:www /data1/logs4、创建Nginx配置文件①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：rm -f /usr/local/webserver/nginx/conf/nginx.confvi /usr/local/webserver/nginx/conf/nginx.conf输入以下内容：引用user  www www;worker_processes 8;error_log  /data1/logs/nginx_error.log  crit;pid        /usr/local/webserver/nginx/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  $binary_remote_addr  10m;server{    listen  80;    server_name  api.weicai.com;    index index.html index.php;    root /data0/www;    access_log  /data1/logs/wwwlogs.log;    location ~ .*\.(php|php5)?$    {        fastcgi_pass 127.0.0.1:9000;        fastcgi_index index.php;                fastcgi_param APPLICATION_ENV product;        include fastcgi.conf;    }    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$    {        expires 30d;    }    location ~ .*\.(js|css)?$    {        expires 1h;    }    location /    {        if (!-e $request_filename) {           #rewrite ^/(\w+)/(.*)$ /$1/index.php last;           rewrite ^(.+)$ /index.php last;        }    }}}

　②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件：

vi /usr/local/webserver/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-redirectfastcgi_param  REDIRECT_STATUS    200;

　 5、启动Nginx

ulimit -SHn 65535/usr/local/webserver/nginx/sbin/nginx

四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

　　在末尾增加以下内容：

ulimit -SHn 65535/usr/local/webserver/php/sbin/php-fpm start/usr/local/webserver/nginx/sbin/nginx/data/mysql/3306/mysql start

五、优化Linux内核参数

vi /etc/sysctl.conf在末尾增加以下内容：引用# Addnet.ipv4.tcp_max_syn_backlog = 65536net.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

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/webserver/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/webserver/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/webserver/nginx/conf/nginx.conf syntax is ok

　　the configuration file /usr/local/webserver/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/webserver/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}'

七、编写每天定时切割Nginx日志的脚本

　　1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh
vi /usr/local/webserver/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 pathlogs_path="/usr/local/webserver/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/webserver/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/webserver/nginx/sbin/cut_nginx_log.sh

Linux下Memcache服务器端的安装

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.gz2.先安装libevent：# tar zxvf libevent-1.2.tar.gz# cd libevent-1.2# ./configure –prefix=/usr# make# make install3.测试libevent是否安装成功：# ls -al /usr/lib | grep libeventlrwxrwxrwx 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.lalrwxrwxrwx 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开启memcache服务端命令/usr/local/bin/memcached -d -m 10  -p 11211 -u root -c 1024 -P /tmp/memcached.pid-d选项是启动一个守护进程，-m是分配给Memcache使用的内存数量，单位是MB，我这里是10MB，-u是运行Memcache的用户，我这里是root，-l是监听的服务器IP地址，如果有多个地址的话，我这里指定了服务器的IP地址192.168.0.200，-p是设置Memcache监听的端口，我这里设置了12000，最好是1024以上的端口，-c选项是最大运行的并发连接数，默认是1024，我这里设置了256，按照你服务器的负载量来设定，-P是设置保存Memcache的pid文件，我这里是保存在 /tmp/memcached.pid，
