先安装编译依赖的一些组件
yum install pcre pcre-devel openssl openssl-devel -y
1、解压程序包
tar xf nginx-1.10.0.tar.gz cd nginx-1.10.0
2、预编译配置参数
./configure --user=www \--group=www \--prefix=/data/server/nginx \--with-http_stub_status_module \--without-http-cache \--with-http_ssl_module \--with-http_gzip_static_module
3、执行编译
make && make install
4、替换配置文件
nginx.conf
user www www;worker_processes 1;error_log /u01/data/log/nginx/error.log crit;pid /u01/data/server/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;log_format main $remote_addr - "$request_time" [$time_local] "$request" \"$status" $body_bytes_sent "$http_referer" \"$http_user_agent" $http_x_forwarded_for;log_format $remote_addr - $remote_user [$time_local] "$request" \$status $body_bytes_sent "$http_referer" \"$http_user_agent" $http_x_forwarded_for "$request_time";include /u01/alidata/server/nginx/conf/vhosts/*.conf;
虚拟主机配置文件模板

5、提供Nginx启动脚本
#!/bin/bash#nginxd=/u01/data/server/nginx/sbin/nginxnginx_config=/u01/data/server/nginx/conf/nginx.confnginx_pid=/u01/data/server/nginx/logs/nginx.pidRETVAL=0prog="nginx"[ -x $nginxd ] || exit 0# Start nginx daemons functions.start() {if [ -e $nginx_pid ] && netstat -tunpl | grep nginx &> /dev/null;thenecho "nginx already running...."exit 1fiecho -n $"Starting $prog!"$nginxd -c ${nginx_config}RETVAL=$?echo[ $RETVAL = 0 ] && touch /var/lock/nginxreturn $RETVAL}# Stop nginx daemons functions.stop() {echo -n $"Stopping $prog!"$nginxd -s stopRETVAL=$?echo[ $RETVAL = 0 ] && rm -f /var/lock/nginx}# reload nginx service functions.reload() {echo -n $"Reloading $prog!"stop() {echo -n $"Stopping $prog!"$nginxd -s stopRETVAL=$?echo[ $RETVAL = 0 ] && rm -f /var/lock/nginx}# reload nginx service functions.reload() {echo -n $"Reloading $prog!"#kill -HUP `cat ${nginx_pid}`$nginxd -s reloadRETVAL=$?echo}# See how we were called.case "$1" instart)start;;stop)stop;;reload)reload;;restart)stopstart;;*)echo $"Usage: $prog {start|stop|restart|reload|help}"exit 1esacexit $RETVAL
只需要稍加修改程序路径就可立即使用
安装 PHP7
PHP官网:/
PHP扩展:/
先安装一些为编译依赖的组建
yum -y install gcc gcc-c++ gcc-g77 make libtool autoconf patch unzip automake libxml2 libxml2-devel ncurses ncurses-devel libtool-ltdl-devel libtool-ltdl libmcrypt libmcrypt-devel libpng libpng-devel libjpeg-devel openssl openssl-devel curl curl-devel libxml2 libxml2-devel ncurses ncurses-devel libtool-ltdl-devel libtool-ltdl autoconf automake libaio*
1、解压程序包
tar xf php-7.0.6.tar.bz2cd php-7.0.6
2、安装编译依赖的图片库
jpegsrc.v6b.tar.gzlibpng-1.2.50.tar.gzfreetype-2.1.10.tar.gz
# 安装 jpegsrc.v6b.tar.gz#这个需要先创建好存放程序的文件夹不然会报错mkdir /usr/local/jpeg.6/{bin,lib,include,man/man1} -pvtar xf jpegsrc.v6b.tar.gz cd jpeg-6b/./configure --prefix=/usr/local/jpeg.6/make && make install# 安装 libpng-1.2.50.tar.gztar xf libpng-1.2.50.tar.gzcd libpng-1.2.50./configure --prefix=/usr/local/libpng.1.2.50make && make install# 安装 freetype-2.1.10.tar.gztar xf freetype-2.1.10.tar.gzcd freetype-2.1.10./configure --prefix=/usr/local/freetype.2.1.10/make && make install
3、预编译配置参数
./configure --prefix=/data/server/php \--enable-opcache \--with-config-file-path=/u01/data/server/php/etc \--enable-mysqlnd \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--enable-fpm \--enable-static \--enable-inline-optimization \--enable-sockets \--enable-wddx \--enable-zip \--enable-calendar \--with-gd \--with-iconv \--with-openssl \--with-zlib \--enable-bcmath \--enable-soap \--with-xmlrpc \--enable-mbstring \--enable-shared \--with-curl \--enable-xml \--enable-ftp \--with-mcrypt \--with-mhash \--enable-shmop \--enable-sysvsem \--enable-mbregex \--enable-gd-native-ttf \--enable-pcntl \--enable-session \--with-gettext \--with-freetype-dir=/usr/local/freetype.2.1.10 \--with-jpeg-dir=/usr/local/jpeg.6 \--with-png-dir=/usr/local/libpng.1.2.50 \--disable-ipv6 \--disable-debug \--disable-maintainer-zts \--disable-rpath \--disable-fileinfo \--without-gdbm \
4、执行编译
make && make install
5、提供php.ini文件
cp php.ini-production /u01/data/server/php/etc/php.ini
配置php.ini
# 在840行左右-设置PHP的opcache和memcache扩展库zend_extension=opcache.soextension=memcache.so# 722行左右-设置PHP的扩展库路径extension_dir = "/u01/data/server/php7/lib/php/extensions/no-debug-non-zts-1012/"# 避免PHP信息暴露在http头中expose_php = Off# 避免暴露php调用mysql的错误信息display_errors = Off# 开启PHP错误日志（路径在php-fpm.conf中配置）log_errors = On# 设置PHP的时区date.timezone = PRC# 开启opcache(1733行左右)opcache.enable=1# 设置PHP脚本允许访问的目录# open_basedir = /usr/share/nginx/html;
6、配置php-fpm
php-fpm.conf 进程服务主配置文件
# 设置错误日志的路径error_log = /var/log/php-fpm/error.log# 引入www.conf文件中的配置include=/usr/local/php7/etc/php-fpm.d/*.conf# 设置主进程打开的最大文件数rlimit_files = 102400www.conf 进程服务扩展配置文件# 设置用户和用户组user = wwwgroup = www# 设置php监听方式# listen = 127.0.0.1:9000 # 注意这里要设置PHP套接字文件的权限，默认是root，Nginx无法访问。listen = /var/run/php-fpm/php-fpm.sock# 开启慢日志slowlog = /var/log/php-fpm/php-slow.logrequest_slowlog_timeout = 10s# 设置工作进程数(根据实际情况设置)pm.max_children = 50# 这里需要注意,pm.start_servers 不能小于 pm.min_spare_serverspm.start_servers = 5pm.min_spare_servers = 5pm.max_spare_servers = 10pm.max_requests = 10240# 设置php的session目录（所属用户和用户组都是www）php_value[session.save_handler] = filesphp_value[session.save_path] = /var/tmp/php/session
7、提供php-fpm启动脚本
#! /bin/sh#prefix=/u01/data/server/php7exec_prefix=${prefix}php_fpm_BIN=${exec_prefix}/sbin/php-fpmphp_fpm_CONF=${prefix}/etc/php-fpm.confphp_fpm_PID=${prefix}/var/run/php-fpm.pidphp_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID"wait_for_pid () {try=0while test $try -lt 35 ; docase "$1" increated)if [ -f "$2" ] ; thentry=\breakfi;; emoved)if [ ! -f "$2" ] ; thentry=\breakfi;;esacecho -n .try=`expr $try + 1`sleep 1done}case "$1" instart)echo -n "Starting php-fpm "$php_fpm_BIN --daemonize $php_optsif [ "$?" != 0 ] ; thenecho " failed"exit 1fiwait_for_pid created $php_fpm_PIDif [ -n "$try" ] ; thenecho " failed"exit 1elseecho " done"fi;;stop)echo -n "Gracefully shutting down php-fpm "if [ ! -r $php_fpm_PID ] ; thenecho "warning, no pid file found - php-fpm is not running ?"exit 1fikill -QUIT `cat $php_fpm_PID`wait_for_pid removed $php_fpm_PIDif [ -n "$try" ] ; thenecho " failed.

H、启动php-fpm程序
/etc/init.d/php-fpm start# 修改套接字文件权限chown -R /var/run/php-fpm/
