初次体验：nginx+php+fastcg+xcache+mysql+openx
nginx+php+fastcg+xcache+mysql+openx说明：本文是使用nginx 安装广告发布系统openx2.4
其中参考文档：张宴BLOG linuxtone.org论坛文档 官方文档 同文发表在：http://www.linuxtone.org/thread-441-1-1.html http://liuyu.blog.51cto.com/183345/82841 及CU个人空间 下次将写为什么我们需要使用nginx 它有那此功能，与apache相比优势在那。 Nginx ("engine x") 是一个高性能的 HTTP 和反向代理服务器，也是一个 IMAP/POP3/SMTP 代理服务器。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的，它已经在该站点运行超过两年半了。Igor 将源代码以类BSD许可证的形式发布。 Nginx官方wiki:http://wiki.codemongers.com/NginxChs openx官方首页：http://www.openx.org php-fpm官网：http://php-fpm.anight.org/index.html 本文安装环境： os:rh8 ,centos5 kernel:2.6 相关软件包：libjpeg libpng freetype libxml2 zlib (这些可以用RPM包安装，相应的开发包也装上*-devel) nginx0.6.31 http://sysoev.ru/nginx/nginx-0.6.31.tar.gz pcre7.7 ftp://ftp.csx.cam.ac.uk/pub/soft ... cre/pcre-7.7.tar.gz php5.2.6 http://www.php.net/get/php-5.2.6.tar.gz/from/this/mirror mysql 5.0 我这里用的压缩版，直接解压设置权限使用的 xcache1.2.2 http://xcache.lighttpd.net/pub/Releases/1.2.2/xcache-1.2.2.tar.gz php-fpm http://php-fpm.anight.org/downlo ... 6-fpm-0.5.8.diff.gz (注意5.0的PHP没有相应的补丁包，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) 同时也可以安装zend openx2.4 http://download.openx.org/openx-2.4.6.tar.gz nginx+php5+fastcgi+xcache+mysql 这套系统还可以安装discuz+zend 安装过程： 一、mysql shell> /usr/sbin/groupadd mysql shell> /usr/sbin/useradd -g mysql mysql shell> groupadd mysql shell> useradd -g mysql mysql shell> cd /usr/local shell> gunzip < /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf - shell> ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql shell> cd mysql shell> scripts/mysql_install_db --user=mysql shell> chown -R root . shell> chown -R mysql data shell> chgrp -R mysql . shell> bin/mysqld_safe --user=mysql & 我这里也是省事，没有选择编译安装，其实最主要是注意权限问题。mysql启动问题就不大。 二、PHP (本人在RH8上也安装成功，就是相关的依赖比较多) shell>tar zxvf php-5.2.6.tar.gz shell>gzip -cd php-5.2.6-fpm-0.5.8.diff.gz | patch -d php-5.2.6 -p1 shell>cd php-5.2.6/ shell>./configure --prefix=/usr/local/php5 --with-mysql=/usr/local/mysql --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-debug --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-gd --with-openssl shell>make && make install shell>cp php.ini-dist /usr/local/php/etc/php.ini 注：没有php5.0 的php-fpm补丁包 参数可由自己定，php5却需要安装gd,libxml2,fastcgi,fpm,mbstring 对于memcache,xcache 可自行选择 gd又依赖：jpeg,png,zlib,freetype,gd2 在编译过程中有可能会遇到一些错误。 一般解决办法为：升级rpm为最新的，并安装相关的依赖包 下载源码包安装到其它目前，编译时指定相关的目录。 具体的情况可以多看./configure --help 三、xcache 给PHP加速(建议安装) shell>tar zxvf xcache-1.2.2.tar.gz shell>cd xcache-1.2.2/ shell>/usr/local/php5/bin/phpize shell>./configure --with-php-config=/usr/local/php5/bin/php-config --enable-xcache shell>make &&make install 四、修改php.ini （可下载附件进行查看） sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts- 20060613/" /usr/local/webserver/php/etc/php.ini sed -i 's#display_errors = On#display_errors = Off#' /usr/local/webserver/php/etc/php.ini 在未尾加入 [xcache-common] zend_extension = /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so [xcache.admin] xcache.admin.user = "xcache" ; xcache.admin.pass = md5($yourpasswd) xcache.admin.pass = "8e6867a5d05144cf4761d6481fc674a8" [xcache] xcache.cacher = On xcache.shm_scheme = "mmap" xcache.size = 32M ; cpu number (cat /proc/cpuinfo |grep -c processor) xcache.count = 2 xcache.slots = 8k xcache.ttl = 0 xcache.gc_interval = 0 xcache.var_size = 2M ; cpu number (cat /proc/cpuinfo |grep -c processor) xcache.var_count = 2 xcache.var_slots = 8K xcache.var_ttl = 0 xcache.var_maxttl = 0 xcache.var_gc_interval = 300 xcache.readonly_protection = Off xcache.mmap_path = "/dev/zero" 五、修改php-fpm.conf （可下载附件进行查看） vi /usr/local/php5/etc/php-fpm.conf 用户组及PHP目录及，其它的一些信息可以根据自己的环境和需求来定 # <?xml version="1.0" ?> # <configuration> # # All relative paths in this config are relative to php's install prefix # # <section name="global_options"> # # Pid file # <value name="pid_file">/usr/local/webserver/php/logs/php-fpm.pid</value> # # Error log file # <value name="error_log">/usr/local/webserver/php/logs/php-fpm.log</value> # # Log level # <value name="log_level">notice</value> # # When this amount of php processes exited with SIGSEGV or SIGBUS ... # <value name="emergency_restart_threshold">10</value> # # ... in a less than this interval of time, a graceful restart will be initiated. # Useful to work around accidental curruptions in accelerator's shared memory. # <value name="emergency_restart_interval">1m</value> # # Time limit on waiting child's reaction on signals from master # <value name="process_control_timeout">5s</value> # # Set to 'no' to debug fpm # <value name="daemonize">yes</value> # # </section> # # <workers> # # <section name="pool"> # # Name of pool. Used in logs and stats. # <value name="name">default</value> # # Address to accept fastcgi requests on. # Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket' # <value name="listen_address">127.0.0.1:9000</value> # # <value name="listen_options"> # # Set listen(2) backlog # <value name="backlog">-1</value> # # Set permissions for unix socket, if one used. # In Linux read/write permissions must be set in order to allow connections from web server. # Many BSD-derrived systems allow connections regardless of permissions. # <value name="owner"></value> # <value name="group"></value> # <value name="mode">0666</value> # </value> # # Additional php.ini defines, specific to this pool of workers. # <value name="php_defines"> # <value name="sendmail_path">/usr/sbin/sendmail -t -i</value> # <value name="display_errors">0</value> # </value> # # Unix user of processes # <value name="user">www</value> # # Unix group of processes # <value name="group">www</value> # # Process manager settings # <value name="pm"> # # Sets style of controling worker process count. # Valid values are 'static' and 'apache-like' # <value name="style">static</value> # # Sets the limit on the number of simultaneous requests that will be served. # Equivalent to Apache MaxClients directive. # Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi # Used with any pm_style. # <value name="max_children">128</value> # # Settings group for 'apache-like' pm style # <value name="apache_like"> # # Sets the number of server processes created on startup. # Used only when 'apache-like' pm_style is selected # <value name="StartServers">20</value> # # Sets the desired minimum number of idle server processes. # Used only when 'apache-like' pm_style is selected # <value name="MinSpareServers">5</value> # # Sets the desired maximum number of idle server processes. # Used only when 'apache-like' pm_style is selected # <value name="MaxSpareServers">250</value> # # </value> # # </value> # # Time limit on waiting execution of single request # Should be used when 'max_execution_time' ini option does not terminate execution for some reason # <value name="request_execution_timeout">31s</value> # # Set open file desc rlimit # <value name="rlimit_files">51200</value> # # Set max core size rlimit # <value name="rlimit_core">0</value> # # Chroot to this directory at the start # <value name="chroot"></value> # # Chdir to this directory at the start # <value name="chdir"></value> # # Redirect workers' stdout and stderr into main error log. # If not set, they will be redirected to /dev/null, according to FastCGI specs # <value name="catch_workers_output">yes</value> # # How much requests each process should execute before respawn. # Useful to work around memory leaks in 3rd party libraries. # For endless request processing please specify 0 # Equivalent to PHP_FCGI_MAX_REQUESTS # <value name="max_requests">51200</value> # # Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect. # Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+) # Makes sense only with AF_INET listening socket. # <value name="allowed_clients">127.0.0.1</value> # # Pass environment variables like LD_LIBRARY_PATH # All $VARIABLEs are taken from current environment # <value name="environment"> # <value name="HOSTNAME">$HOSTNAME</value> # <value name="PATH">/usr/local/bin:/usr/bin:/bin</value> # <value name="TMP">/tmp</value> # <value name="TMPDIR">/tmp</value> # <value name="TEMP">/tmp</value> # <value name="OSTYPE">$OSTYPE</value> # <value name="MACHTYPE">$MACHTYPE</value> # <value name="MALLOC_CHECK_">2</value> # </value> # # </section> # # </workers> # # </configuration> 启动php-cgi /usr/local/php5/sbin/php-fpm start(stop) 六、建立nginx运行的用户及组 /usr/sbin/groupadd www -g 48 /usr/sbin/useradd -u 48 -g www www php-fpm也用此用户及组启动 七、安装nginx tar zxvf pcre-7.7.tar.gz cd pcre-7.7/ ./configure make && make install cd ../ tar zxvf nginx-0.6.31.tar.gz cd nginx-0.6.31/ ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module make && make install 编译安装速度超快。不需要像apache那样漫长的等待，我这里并没有发生错误。呵 八、配置启动nginx 配置fcgi 见附件 /usr/local/nginx/sbin/nginx 相关命令： /usr/local/nginx/sbin/nginx -t 测试配置文件 /usr/local/nginx/sbin/nginx -v 查看相关版本 /usr/local/nginx/sbin/nginx –c </path/to/config>为nginx指定配置文件 退出nginx kill –QUIT nginx_pid 重启nginx kill -HUP nginx-pid 笨方法就是：ps -ef |grep nginx 再kill pid 九、nginx启动脚本(linuxtone.org) vi /etc/init.d/nginx chkconfig --level 35 nginx on #!
