nginx的有以下八大优点: 1.高并发连接:官方测试能支撑5万并发连接,在实际生产环境中跑到2,~3W并发连接。 2.内存消耗少:在3W并发连接下,开启的10个NGINX进程才消耗150M内存(15M*10=150M) 3.配置文件非常简单:风格跟程序一样通俗易懂。 4.成本低廉:Nginx作为开源软件,可以免费使用,而购买F5 BIG-IP、NetScaler 等硬件负载均衡交换机则需要十多万至几十万人民币。 5.支持rewrite重写规则:能够根据域名、URL的不同,将HTTP请求分发到不同的后端服务器群组。 6.内置的健康检查功能:如果Nginx Proxy后端的后台web服务器宕机了,不会音响前端访问。 7.节省带宽:支持GZIP压缩,可以添加浏览器本地缓存的Header头。 8.稳定性高:用于反向代理,宕机的概率微乎其微 一、编译安装Nginx (安装nginx之前需要安装pcre包和zlib以支持重写,正则以及网页压缩等等) (1)首先配置安装pcre: cd /usr/src &&tar xzf pcre-8.01.tar.gz &&cd pcre-8.01 && ./configure --prefix=/usr/local/pcre &&make &&make install (2)然后再编译安装nginx : useradd www && cd /usr/src && tar xzf nginx-0.7.61.tar.gz &&cd nginx-0.7.61 && ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-openssl=/usr/ --with-pcre=/usr/src/pcre-8.01 --user=www --group=www &&make &&make install 【nginx注意* --with-pcre=/usr/src/pcre-8.01指向的是源码包解压的路径,而不是安装的路径,否则会报 make[1]: *** [/usr/local/pcre/Makefile] Error 127 错误】 二、接下来安装mysql (1)、cd /usr/src && tar xzf mysql-5.1.41.tar.gz && cd mysql-5.1.41 && ./configure --prefix=/usr/local/mysql/ --enable-assembler --with-extra-charsets=complex (2)、mysql安装完毕,创建mysql用户和组并初始化数据库,并启动数据库。 cd /usr/local/mysql && useradd mysql && chown -R mysql:mysql /usr/local/mysql && /usr/local/mysql/bin/mysql_install_db --user=mysql && chown -R mysql:mysql var/ && ./bin/mysqld_safe --user=mysql & 【如果mysql启动报错,请检查 /usr/local/mysql/var 目录,mysql是否有权限】 三、安装 php : cd /usr/src &&tar xzf php-5.3.5.tar.gz && cd php-5.3.5 && ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/u sr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-li bxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fpm --enable-sockets && make &&make install 安装完毕!【注意这个参数在此可以不加--enable-fastcgi;其他之前版本需要加上,以上安装根据自己的选择添加,如果报错,根据具体报错找原因】 四、整合Nginx和php(FastCGI)安装完php-5.3.5后支持fastCGI (1)、配置nginx ,拷贝nginx配置文件: user www www; worker_processes 8; error_log /usr/local/nginx/logs/error.log crit; pid /usr/local/nginx/nginx.pid; #Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 51200; events { use epoll; worker_connections 51200; } http { include mime.types; default_type application/octet-stream; charset utf-8; error_page 400 404 403 500 502 503 http://blog.mgcrazy.com; server_names_hash_bucket_size 128; client_header_buffer_size 2k; large_client_header_buffers 4 4k; client_max_body_size 8m; sendfile on; tcp_nopush on; keepalive_timeout 60; fastcgi_cache_path /usr/local/nginx/fastcgi_cache levels=1:2 keys_zone=TEST:10m inactive=5m; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 4k; fastcgi_buffers 8 4k; fastcgi_busy_buffers_size 8k; fastcgi_temp_file_write_size 8k; ##如下设置fastcGI_cache缓存,加速你的web站点! fastcgi_cache TEST; fastcgi_cache_valid 200 302 1h; fastcgi_cache_valid 301 1d; fastcgi_cache_valid any 1m; fastcgi_cache_min_uses 1; fastcgi_cache_use_stale error timeout invalid_header http_500; fastcgi_cache_key http://$host$request_uri; open_file_cache max=204800 inactive=20s; open_file_cache_min_uses 1; open_file_cache_valid 30s; tcp_nodelay on; 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; ##设置301跳转,让二级域名跳转到你规定的url; server { listen 80; server_name blog.mgcrazy.com wgkgood.gicp.net linux.mgcrazy.com; if ($host = 'wgkgood.gicp.net' ) { rewrite ^/(.*)$ http://blog.mgcrazy.com/$1 permanent; } if ($host = 'linux.mgcrazy.com' ) { rewrite ^/(.*)$ http://blog.mgcrazy.com/$1 permanent; } index index.php index.htm index.html; root /home/webapps/www; #limit_conn crawler 20; location ~ .*/.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*/.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*/.(js|css)?$ { expires 1h; } log_format access '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; access_log /usr/local/nginx/logs/access.log access; } } Nginx配置完毕!启动nginx ; (2)、配置fcgi.conf文件如下 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-redirect fastcgi_param REDIRECT_STATUS 200; 五、配置php配置文件: cd /usr/local/php5/etc/ && cp php-fpm.conf.default php-fpm.conf 然后根据提示编辑php-fpm.conf里面的选项。 开启php-fpm cp 六、安装apc配置: cd /usr/src && tar xzf APC-3.1.4.tgz &&cd APC-3.1.4 /usr/local/php5/bin/phpize && ./configure --enable-apc --enable-apc-mmap --with-php-config=/usr/local/php5/bin/php-config &&make&& make install 安装完后会生成一个apc.so在 七、安装memcached,使fastcGI支持memcached 首先安装libevent cd /usr/src && tar xzf libevent-1.4.12-stable.tar.gz && cd libevent-1.4.12-stable && ./configure –prefix=/usr/local/libevent &&make && make install 然后安装memcached //缓存加速 tar xzf memcache-2.2.5.tar.gz && cd memcache-2.2.5 && /usr/local/php5/bin/phpize && ./configure –prefix=/usr/local/memcached --with-libevent=/usr/local/libevent --with-php-config=/usr/local/php5/bin/php-config &&make &&make install 本文出处: https://www.toutiao.com/a6974376287594988040/ |
