Linux系统下编译安装Nginx服务器

http://sourceforge.net/projects/pcre/files/pcre (PCRE正则表达式库官方网址) 

安装NGINX前要先安装PCRE正则表达式库:

./configure --prefix=/usr/local/pcre 出现以下错误 (一般./configure即可, 笔者这里是直接./configure命令)

configure: error: You need a C++ compiler for C++ support. (解决办法: yum install -y gcc gcc-c++)

make

make install

下面开始安装NGINX:

安装NGINX:

yum install libtool

yum install zlib zlib-devel

yum install openssl

./configure --prefix=/usr/local/nginx --with-http_stub_status_module

make

make install

检查是否安装成功:

cd /usr/local/nginx/sbin

./nginx -t

./nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

从错误看出是缺少lib文件导致，进一步查看下:

ldd $(which /usr/local/nginx/sbin/nginx)

可以看出 libpcre.so.1 => not found 并没有找到，进入/lib目录中手动链接下(这里的/lib目录指的是系统的根目录下面的lib目录)

32位系统 [[email protected] lib]# ln -s /usr/local/lib/libpcre.so.1 /lib

64位系统 [[email protected] lib]# ln -s /usr/local/lib/libpcre.so.1 /lib64

结果显示：

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

启动nginx:

cd /usr/local/nginx/sbin 目录下面 输入 ./nginx 启动nginx

ps -ef|grep nginx

netstat -nap|grep :80//查看80端口被哪个进程占用

service iptables stop//把防火墙打开,否则nginx不能被访问

--------------------------------------------------------------------------------------------------

安装完nginx后需要配置监听的IP地址和端口，笔者这里是针对memcached+tomcat6做的配置，进入nginx的安装目录，笔者这里是/usr/local/nginx/conf这个目录，打开nginx.conf这个文件做如下修改:

[[email protected] conf]# less nginx.conf

#user nobody;

#user www www;

worker_processes 1;

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid;

pid /usr/local/nginx/logs/nginx.pid;

events {

use epoll;

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

include /usr/local/nginx/conf/proxy.conf; #一定要指向代理文件

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

# '$status $body_bytes_sent "$http_referer" '

# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;

#tcp_nopush on;

tcp_nopush on;

#keepalive_timeout 0;

keepalive_timeout 65;

#gzip on;

upstream backend {

# ip_hash;

server 192.168.0.93:8080;

server 192.168.0.92:8080;

#jvm_route $cookie_JSESSIONID|sessionid reverse;

}

server {

listen 80;

server_name 192.168.0.93;

#charset koi8-r;

charset utf-8;

#access_log logs/host.access.log main;

location / {

root html;

index index.html index.htm;

proxy_pass http://backend;

#proxy_redirect default;

proxy_set_header XReal-IP $remote_addr;

proxy_connect_timeout 10;

#client_max_body_size 100m;

}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html

#

location ~^/(WEB-INF)/ {

deny all;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#

#location ~ .php$ {

# proxy_pass http://127.0.0.1;

#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

#location ~ .php$ {

# root html;

# fastcgi_pass 127.0.0.1:9000;

# fastcgi_index index.php;

# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

# include fastcgi_params;

#}

# deny access to .htaccess files, if Apache's document root

# concurs with nginx's one

#

#location ~ /.ht {

# deny all;

#}

}

# another virtual host using mix of IP-, name-, and port-based configuration

#

#server {

# listen 8000;

# listen somename:8080;

# server_name somename alias another.alias;

# location / {

# root html;

# index index.html index.htm;

# }

#}

# HTTPS server

#

#server {

# listen 443;

# server_name localhost;

# ssl on;

# ssl_certificate cert.pem;

# ssl_certificate_key cert.key;

# ssl_session_timeout 5m;

# ssl_protocols SSLv2 SSLv3 TLSv1;

# ssl_ciphers HIGH:!aNULL:!MD5;

# ssl_prefer_server_ciphers on;

# location / {

# root html;

# index index.html index.htm;

# }

#}

}

还需要在/usr/local/nginx/conf目录下手动建立proxy.conf文件，内容如下:

proxy_redirect off;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr; #获取真实IP

#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #获取代理者的真实ip

client_max_body_size 10m;

client_body_buffer_size 128k;

proxy_connect_timeout 90;

proxy_send_timeout 90;

proxy_read_timeout 90;

proxy_buffer_size 4k;

proxy_buffers 4 32k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

最后的/usr/local/nginx/conf目录下文件截图如下:

--------------------------------------------------------------------------------------------------

最后再多提一句日志的问题，nginx的默认日志目录为/usr/local/nginx/logs目录，这个目录下面有3个文件，分别是access.log,error.log和nginx.pid，其中error.log是错误日志，如果在启动nginx时遇到错误可以到这里来查看错误问题。
