PHP + Nginx 環境安裝

安裝PHP

卸載舊的PHP版本

yum remove php
yum remove php-common.x86_64

安裝必要擴展包

yum install -y gcc gcc-c++ make cmake bison autoconf wget lrzsz
yum install -y libtool libtool-ltdl-devel
yum install -y freetype-devel libjpeg.x86_64 libjpeg-devel libpng-devel gd-devel
yum install -y python-devel patch sudo
yum install -y openssl* openssl openssl-devel ncurses-devel
yum install -y bzip* bzip2 unzip zlib-devel
yum install -y libevent*
yum install -y libxml* libxml2-devel
yum install -y libcurl* curl-devel
yum install -y readline-devel
yum install libmcrypt libmcrypt-devel mcrypt mhash

下載、解壓、編譯、安裝

wget http://cn2.php.net/distributions/php-7.0.17.tar.gz

tar -zvxf php-7.0.17.tar.gz

chmod 755 /etc/init.d/php-fpm7
chkconfig php-fpm7 on
service php-fpm7 start #啓動服務
killall php-fpm #中止php-fpm

安裝Nginx

• 安裝過程略

爲Nginx新增模塊

• 個人Nginx爲源碼安裝，源碼目錄爲/usr/local/src/nginx-1.8.1

cd /usr/local/src/nginx-1.8.1
./configure --prefix=/usr/local/nginx --sbin-path=/usr/sbin/nginx --conf-path=/usr/local/nginx/config/nginx.conf --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --user=www --group=www --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/tmp/nginx/client --http-proxy-temp-path=/var/tmp/nginx/proxy --http-fastcgi-temp-path=/var/tmp/nginx/fcgi --with-http_stub_status_module

make
cp objs/nginx /usr/local/nginx/sbin/nginx

Nginx配置支持PHP

• nginx.conf

http {
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    client_max_body_size 50m;
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 60;
    tcp_nodelay on;
    fastcgi_connect_timeout 600;
    fastcgi_send_timeout 600;
    fastcgi_read_timeout 600;
    fastcgi_buffer_size 64k;
    fastcgi_buffers 4 64k;
    fastcgi_busy_buffers_size 128k;
    fastcgi_temp_file_write_size 256k;
    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;
    gzip_proxied expired no-cache no-store private auth;
    gzip_disable "MSIE [1-6]\.";
    server_tokens off;
    log_format access '$remote_addr - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" $http_x_forwarded_for';
    
    include vhost/*.conf;
}

• vhost/xxx.conf(vhost和nginx.conf同級)

server {
    listen 80;
    server_name api.gnfenqi.com;
    access_log /alidata/log/nginx/api.log combined;
    index index.html index.htm index.php;
    root /alidata/www/api.gnfenqi.com;
        if ( $query_string ~* ".*[\;'\<\>].*" ){
        return 404;
    }
    location / {
        try_files $uri $uri/ /index.php;
    }
    location ~ .*\.(php|php5)?$ {
        fastcgi_pass unix:/dev/shm/php-cgi.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
        expires 30d;
    }
    location ~ .*\.(js|css)?$ {
        expires 7d;
    }
}

PHP7 下安裝 memcache 和 memcached 擴展

Memcached 是高性能的分佈式內存緩存服務器，而PHP memcache 和 memcached 都是 Memcached 服務器的 PHP 擴展。其中memcache 比 memcached 早出現，因此一些老的代碼可能還在用 memcache 擴展。memcached 後來出現，而且大部分框架都支持 memcached，如今相對較流行。能夠根據本身須要，安裝一個就能夠。這裏兩個的安裝方法都說一下。

參考：http://www.lnmp.cn/install-memcache-and-memcached-extends-under-php7.html

• 安裝memcached擴展
• memcached擴展須要libmemcached客戶端庫
• 安裝libmemcached
