1.安装说明：
系统环境：Ubuntu 14.04.3 LTS
软件：nginx-1.8.0.tar.gz
安装位置：/opt/nginx
2.安装
需要用到的安装包：
openssl-fips-2.0.10.tar.gz
zlib-1.2.8.tar.gz
pcre-8.37.tar.gz
nginx-1.8.0.tar.gz
安装顺序依次为:openssl、zlib、pcre, 然后安装Nginx包
2.1安装openssl-fips-2.0.2.tar.gz
tar –zxvf openssl-fips-2.0.10.tar.gz
cd openssl-fips-2.0.10
./config
make
make install
2.2 安装zlib-1.2.8.tar.gz
tar –zxvf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make
make install
2.3安装pcre-8.37.tar.gz (需安装编译c++环境: apt-get install build-essential)
在安装pcre-8.37.tar.gz之前需要安装c++编译环境，否则在执行./configure时会报错。
apt-get install build-essential
tar –zxvf pcre-8.37.tar.gz
cd pcre-8.37
./configure
make
make install
2.4安装nginx-1.8.0.tar.gz
tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --with-pcre=../pcre-8.37 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-fips-2.0.10
make
make install
至此Nginx的安装完成!
检测nginx是否安装成功
cd /usr/local/nginx/sbin
./nginx –t
出现如下所示提示,表示安装成功
root :/usr/local/nginx/sbin# ./nginx -t
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
./ngixn
查看端口：
netstat -tnlp | grep nginx
root :/usr/local/nginx/sbin# netstat -tnlp | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 2957/nginx
并且通过浏览器访问
3.nginx负载均衡配置
打开 /usr/local/nginx/conf/nginx.conf 配置文件，做如下配置即可：
user root root;worker_processes 1; #error_log logs/error.log;#error_log logs/error.log notice;error_log logs/error.log warn; pid logs/nginx.pid; events { worker_connections 1024;} http { include mime.types; default_type application/octet-stream; #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; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; #设定负载均衡的服务器列表 upstream myserver{ server 192.168.1.171:8080; server 192.168.1.172:8080; server 192.168.1.173:8080; } #侦听服务器信息 server { listen 80; server_name 192.168.1.110; #charset koi8-r; #access_log logs/host.access.log main; location / { #root html; #index index.html index.htm; proxy_pass http://myserver; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # 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 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
