[操作系统]nginx+php

相信大家将这三者部署到同一台主机应该已经不陌生了,今天在这里,给大家演示一下如何将三者部署到三台主机上。

实验系统:CentOS 6.6_x86_64

实验前提:大部分软件使用编译安装,请提前准备好编译环境,防火墙和selinux都关闭

实验软件:nginx-1.9.3 mariadb-10.0.20 php-5.6.11 memcache-2.2.7 xcache-3.2.0

实验拓扑:

一、安装nginx

  1.解决依赖关系:

    需要专门安装pcre-devel包:

1 yum -y install pcre-devel

  2.添加nginx用户:

1 useradd -r nginx

  3.解压并编译安装nginx:

 1 tar xf nginx-1.9.3.tar.gz  2 cd nginx-1.9.3 3 ./configure \ 4  --prefix=/usr/local/nginx \                    //安装位置 5  --sbin-path=/usr/local/nginx/sbin/nginx \            //程序文件 6  --conf-path=/etc/nginx/nginx.conf \               //配置文件安装位置 7  --error-log-path=/var/log/nginx/error.log \           //错误日志安装位置 8  --http-log-path=/var/log/nginx/access.log \           //访问日志安装位置 9  --pid-path=/var/run/nginx/nginx.pid \              //pid文件位置10  --lock-path=/var/lock/nginx.lock \                //锁文件位置11  --user=nginx \                            //运行进程时使用的用户身份12  --group=nginx \                           //运行进程时使用的用户组13  --with-http_ssl_module \                      //支持ssl模块14  --with-http_flv_module \                      //支持flv模块15  --with-http_stub_status_module \                 //支持stub_status模块16  --with-http_gzip_static_module \                 //支持gzip_static模块17  --http-client-body-temp-path=/var/tmp/nginx/client/ \    //存储HTTP客户端请求body体的临时文件位置18  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \        //存储HTTP代理的临时文件位置19  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \        //存储fasycgi临时文件位置20  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \         //存储uwsgi临时文件位置21  --http-scgi-temp-path=/var/tmp/nginx/scgi \          //存储scgi临时文件位置22  --with-pcre                             //支持pcre库23 make && make install

  4.提供脚本文件:

 1 vim /etc/init.d/nginx 2 -------------------------------- 3 #!/bin/sh 4 # 5 # nginx - this script starts and stops the nginx daemon 6 # 7 # chkconfig:  - 85 15  8 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ 9 #        proxy and IMAP/POP3 proxy server 10 # processname: nginx 11 # config:   /etc/nginx/nginx.conf 12 # config:   /etc/sysconfig/nginx 13 # pidfile:   /var/run/nginx.pid 14  15 # Source function library. 16 . /etc/rc.d/init.d/functions 17  18 # Source networking configuration. 19 . /etc/sysconfig/network 20  21 # Check that networking is up. 22 [ "$NETWORKING" = "no" ] && exit 0 23  24 nginx="/usr/local/nginx/sbin/nginx" 25 prog=$(basename $nginx) 26  27 NGINX_CONF_FILE="/etc/nginx/nginx.conf" 28  29 [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx 30  31 lockfile=/var/lock/subsys/nginx 32  33 make_dirs() { 34  # make required directories 35  user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -` 36  options=`$nginx -V 2>&1 | grep 'configure arguments:'` 37  for opt in $options; do 38    if [ `echo $opt | grep '.*-temp-path'` ]; then 39      value=`echo $opt | cut -d "=" -f 2` 40      if [ ! -d "$value" ]; then 41        # echo "creating" $value 42        mkdir -p $value && chown -R $user $value 43      fi 44    fi 45  done 46 } 47  48 start() { 49   [ -x $nginx ] || exit 5 50   [ -f $NGINX_CONF_FILE ] || exit 6 51   make_dirs 52   echo -n $"Starting $prog: " 53   daemon $nginx -c $NGINX_CONF_FILE 54   retval=$? 55   echo 56   [ $retval -eq 0 ] && touch $lockfile 57   return $retval 58 } 59  60 stop() { 61   echo -n $"Stopping $prog: " 62   killproc $prog -QUIT 63   retval=$? 64   echo 65   [ $retval -eq 0 ] && rm -f $lockfile 66   return $retval 67 } 68  69 restart() { 70   configtest || return $? 71   stop 72   sleep 1 73   start 74 } 75  76 reload() { 77   configtest || return $? 78   echo -n $"Reloading $prog: " 79   killproc $nginx -HUP 80   RETVAL=$? 81   echo 82 } 83  84 force_reload() { 85   restart 86 } 87  88 configtest() { 89  $nginx -t -c $NGINX_CONF_FILE 90 } 91  92 rh_status() { 93   status $prog 94 } 95  96 rh_status_q() { 97   rh_status >/dev/null 2>&1 98 } 99 100 case "$1" in101   start)102     rh_status_q && exit 0103     $1104     ;;105   stop)106     rh_status_q || exit 0107     $1108     ;;109   restart|configtest)110     $1111     ;;112   reload)113     rh_status_q || exit 7114     $1115     ;;116   force-reload)117     force_reload118     ;;119   status)120     rh_status121     ;;122   condrestart|try-restart)123     rh_status_q || exit 0124       ;;125   *)126     echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"127     exit 2128 esac129 --------------------------------130 chmod +x /etc/init.d/nginx131 chkconfig --add nginx132 chkconfig nginx on133 service nginx start

  5.测试访问页面,nginx安装完毕:

二、安装mysql

  1.添加mysql用户和创建数据目录:

1 useradd -r mysql2 mkdir -pv /mydata/data3 chown -R mysql:mysql /mydata/data

  2.解压并初始化mysql:

1 tar xf mariadb-10.0.20-linux-x86_64.tar.gz -C /usr/local/2 cd /usr/local/3 ln -sv mariadb-10.0.20-linux-x86_64 mysql4 cd mysql/5 chown -R root:mysql .6 scripts/mysql_install_db --user=mysql --datadir=/mydata/data/

  3.提供配置文件:

1 cp support-files/my-large.cnf /etc/my.cnf2 vim /etc/my.cnf3 修改此文件中thread_concurrency的值为你的CPU个数乘以2,比如:thread_concurrency = 24 另外还需要添加如下行指定mysql数据文件的存放位置:datadir = /mydata/data

  4.提供脚本文件:

1 cp support-files/mysql.server /etc/init.d/mysqld2 chkconfig --add mysqld3 chkconfig mysqld on4 service mysqld start

  使用mysql目录的下的bin/mysql去连接mysql,出现如下画面表示连接成功:

  5.输出mysql的man手册至man命令的查找路径:   

    编辑/etc/man.config,添加如下行即可:MANPATH  /usr/local/mysql/man

  6.输出mysql的头文件至系统头文件路径/usr/include:
    这可以通过简单的创建链接实现: 
1 ln -sv /usr/local/mysql/include /usr/include/mysql

  7.输出mysql的库文件给系统库查找路径:

1 echo '/usr/local/mysql/lib' > /etc/ld.so.conf.d/mysql.conf2 ldconfig

三、安装PHP

  1.解决依赖关系:

1 yum -y install libbzip2-devel libcurl-devel libmcrypt-devel

  2.编译安装php:

 1 ./configure --prefix=/usr/local/php \      //安装位置 2 --with-mysql \                   //支持mysql 3 --with-pdo-mysql \                //支持pdo模块 4 --with-mysqli \                  //支持mysqli模块          5 --with-openssl \                  //支持openssl模块 6 --enable-fpm \                   //支持fpm模式 7 --enable-sockets \                //启用socket支持 8 --enable-sysvshm \                //启用系统共享内存支持 9 --enable-mbstring \                //使多字节字符串的支持10 --with-freetype-dir \              //设置FreeType安装前缀路径11 --with-jpeg-dir \                //设置libjpeg安装前缀路径12 --with-png-dir \                //设置libpng安装前缀路径13 --with-zlib-dir \                //设置libz安装前缀路径14 --with-libdir=/usr \            //设置lib15 --enable-16 --with-mhash \                 //支持mhash17 --with-mcrypt \                 //支持mcrypt18 --with-config-file-path=/etc \        //配置文件路径19 --with-config-file-scan-dir=/etc/php.d \  //配置文件扫描路径20 --with-bz2 \                  //支持BZip221 --with-curl                   //支持curl22 make && make install  

  3.提供配置文件:

1 cp php.ini-production /etc/php.ini

  4.为php-fpm提供脚本:

1 cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm2 chmod +x /etc/init.d/php-fpm3 chkconfig --add php-fpm4 chkconfig php-fpm on

  5.提供php-fpm配置文件并编辑:

1 cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf2 ------------------------------------------------------3 pm.max_children = 1504 pm.start_servers = 85 pm.min_spare_servers = 56 pm.max_spare_servers = 107 pid = /usr/local/php/var/run/php-fpm.pid

  6.启动php-fpm服务:
1 service php-fpm start

四、整合nginx与PHP

  1.nginx服务器建立网页文件存放目录/www,并修改其权限:

1 mkdir /www2 chown -R nginx:nginx /www

  2.修改nginx配置文件:

 1 vim /etc/nginx/nginx.conf 2 -------------------------------------- 3 location / { 4       root  /www; 5       index index.php index.html index.htm; 6     } 7  8 location ~ \.php$ { 9       root      /www;10       fastcgi_pass  192.168.19.92:9000;11       fastcgi_index index.php;12       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;13       include    fastcgi_params;14     }

  3.修改fastcgi_params文件为:

 1 fastcgi_param GATEWAY_INTERFACE CGI/1.1; 2 fastcgi_param SERVER_SOFTWARE  nginx; 3 fastcgi_param QUERY_STRING    $query_string; 4 fastcgi_param REQUEST_METHOD   $request_method; 5 fastcgi_param CONTENT_TYPE    $content_type; 6 fastcgi_param CONTENT_LENGTH   $content_length; 7 fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name; 8 fastcgi_param SCRIPT_NAME    $fastcgi_script_name; 9 fastcgi_param REQUEST_URI    $request_uri;10 fastcgi_param DOCUMENT_URI    $document_uri;11 fastcgi_param DOCUMENT_ROOT   $document_root;12 fastcgi_param SERVER_PROTOCOL  $server_protocol;13 fastcgi_param REMOTE_ADDR    $remote_addr;14 fastcgi_param REMOTE_PORT    $remote_port;15 fastcgi_param SERVER_ADDR    $server_addr;16 fastcgi_param SERVER_PORT    $server_port;17 fastcgi_param SERVER_NAME    $server_name;

  4.在PHP服务器上,建立nginx用户,要保证和nginx服务器上的nginx用户id号、组id号一致:
  5.修改php-fpm配置文件,并重启:
1 vim /usr/local/php/etc/php-fpm.conf2 ---------------------------------------------3 listen = 192.168.19.92:9000       //监听物理网卡地址,供其它机器调用4 user = nginx              //php-fpm以nginx用户运行5 group = nginx6 ---------------------------------------------7 service php-fpm restart

  6.在PHP服务器上创建/www目录,并开启nfs服务:

1 mkdir /www2 chown -R nginx:nginx /www3 vim /etc/exports4 ---------------------------------------------5 /www  192.168.19.0/24(rw,no_root_squash)6 ---------------------------------------------7 service nfs start

  7.nginx服务器挂载nfs文件,并测试php,测试成功后删除index.php:

1 mount -t nfs 192.168.19.92:/www /www2 vim /www/index.php3 ---------------------------------------4 <?php5    phpinfo();6 ?>7 --------------------------------------8 service nginx restart

五、整合PHP与MYSQL

  在mysql服务器上创建php服务器能够访问的数据库和用户:

1 /usr/local/mysql/bin/mysql2 --------------------------------------------3 CREATE DATABASE wordpress;4 GRANT ALL ON wordpress.* TO 'wordpress'@'192.168.19.92' IDENTIFIED BY '123456';5 FLUSH PRIVILEGES;

六、安装wordpress

  1.在/www文件夹下放入网页文件

  2.访问http://192.168.19.83,并按提示进行安装,配置没问题则会安装成功

七、为php安装xcache

  1.解压并安装:

1 tar xf xcache-3.2.0.tar.gz 2 cd xcache-3.2.03 /usr/local/php/bin/phpize4 ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config5 make && make install

    完成后,会出现:Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

  2.加载模块:

1 vim /etc/php.ini2 -----------------------------------3 extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/xcache.so    //找到extension配置的地方,加上此句

八、为php安装memcache

  1.解压并安装:

1 tar xf memcache-2.2.7.tgz 2 cd memcache-2.2.73 /usr/local/php/bin/phpize4 ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache5 make && make install

    完成后,会出现:Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

  2.加载模块:

1 vim /etc/php.ini2 -----------------------------------3 extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/memcache.so    //找到extension配置的地方,加上此句

  3.两个加速模块都安装完毕,重启php-fpm:

1 service php-fpm restart

  4.创建一个php测试页,并查看模块是否加载成功:
