構建LANMP架構二：源碼安裝nginx及簡單應用

yum install pcre-devel -y
yum install openssl-devel -y

tar zxvf nginx-1.0.2.tar.gz

優化安裝

cd nginx-1.0.8

vi auto/cc/gcc   

#CFLAGS=」$CFLAGS -g」 (註釋掉這行，去掉debug模式編譯，編譯之後程序只有幾百k)

vi src/core/nginx.h
#define NGINX_VERSION "1.0.2」
#define NGINX_VER "nginx" (修改此行,去掉後面的「NGINX_VERSION」,爲了安全，這樣編譯後
外界沒法獲取程序的版本號)

useradd -M -s /sbin/nologin nginx

./configure --prefix=/usr/local/lnmp/nginx --user=nginx --with-http_stub_status_module --withhttp_
ssl_module
make && make install

vi /usr/local/lnmp/nginx/conf/nginx.conf
user nginx nginx;
worker_processes 1;
events {
use epoll; /wiki.nginx.org/ 能夠查到調優參數
worker_connections 1024;

}
server {
listen 80;
server_name desktop144.example.com;
/usr/local/lnmp/nginx/sbin/nginx 啓動程序
vi ~/.bash_profile                                   
PATH=$PATH:$HOME/bin:/usr/local/lnmp/mysql/bin:/usr/local/lnmp/nginx/sbin
nginx -t                                           檢測語法
nginx 運行
nginx -s                                          reload stop

nginx  加密

vi nginx.conf
server {
listen 443;
server_name desktop144.example.com;
ssl on;
ssl_certificate cert.pem; 同時指定pem
ssl_certificate_key cert.pem;
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;
}
}

在 /etc/pki/tls/certs下建立證書
mv cert.pem /usr/local/lnmp/nginx/conf/    將證書放到指定位置

虛擬主機   編輯nginx主配置文件nginx.conf

log_format main '$remote_addr - $remote_user [$time_local] "$request" ' 指定日誌格式
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main; 指定日誌main                       取消"#"

server {
listen 80;
server_name www.example1.com;
access_log logs/example2.access.log main;
location / {
index index.html;
root html/example1.com;
}
}
server {
listen 80;
server_name www.example2.com;
access_log logs/example2.access.log main;
location / {
index index.html;
root html/example2.com;
}
}

負載均衡

主ip192.168.0.144
輔助2apache 192.168.0.66 192.168.0.126           爲方便輔助就用apache了   
vi nginx.conf
http {
upstream myproject {
server 192.168.0.66:80 weight=3; 權重：連續3次後切換126
server 192.168.0.126:80;
}
server {
listen 80;
server_name www.example.com;
location / {
proxy_pass http://myproject;
}
vi /etc/hosts
192.168.0.144 www.example.com 在客戶機上添加主機名 能夠訪問
