centos6.5生产环境编译安装nginx-1.11.3并增加第三方模块ngx_cache_purge、nginx_upstream_check、ngx_devel_kit、lua-nginx

1.安装依赖包
yum install -y gcc gcc-c++ pcre-devel openssl-devel geoip-devel


2.下载需要的安装包
LuaJIT-2.0.4.zip
lua-nginx-module-master.zip
nginx_upstream_check_module-master.zip
nginx-1.11.3.tar.gz
ngx_cache_purge-2.3.tar.gz
ngx_devel_kit-master.zip


3.编译安装LuaJIT-2.0.4.zip(lua-nginx-module-master依赖uaJIT)
unzip LuaJIT-2.0.4.zip
cd LuaJIT-2.0.4
make && make install
ln -s /usr/local/lib/libluajit-5.1.so.2 /usr/lib64/libluajit-5.1.so.2


解压其他第三方模块压缩包
tar -zxvf nginx-1.11.3.tar.gz 
tar -zxvf ngx_cache_purge-2.3.tar.gz 
unzip nginx_upstream_check_module-master.zip 
unzip ngx_devel_kit-master.zip 
unzip lua-nginx-module-master.zip


cd nginx-1.11.3


隐藏版本信息
方法1(需要安装成功后修改配置文件缺点是仍然显示nginx)：
vim /etc/nginx/nginx.conf
加入：
server_tokens off;
http {
    include       mime.types;
    server_tokens off;


fastcgi.conf
sed -i 's#fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;#fastcgi_param  SERVER_SOFTWARE    yaya;#g' /etc/nginx/fastcgi.conf
找到：
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
改为：
fastcgi_param SERVER_SOFTWARE yaya;


方法2推荐(修改源码头文件信息编译)：
vim src/core/nginx.h


#define NGINX_VER          "yaya"
#define NGINX_VAR          "yaya"


测试环境编译参数(增加--with-debug)：


./configure --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --with-debug --pid-path=/var/run/nginx/nginx.pid --with-pcre --with-http_gzip_static_module --with-http_ssl_module --with-http_realip_module --with-http_geoip_module --add-module=../nginx_upstream_check_module-master --add-module=../ngx_cache_purge-2.3 --add-module=../ngx_devel_kit-master/ --add-module=../lua-nginx-module-master/ --with-http_stub_status_module


生产环境编译参数：
./configure --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx/nginx.pid --with-pcre --with-http_gzip_static_module --with-http_ssl_module --with-http_realip_module --with-http_geoip_module --add-module=../nginx_upstream_check_module-master --add-module=../ngx_cache_purge-2.3 --add-module=../ngx_devel_kit-master/ --add-module=../lua-nginx-module-master/ --with-http_stub_status_module


make && make install


4.服务脚本添加/etc/init.d/nginx、隐藏版本信息
/etc/init.d/nginx


#! /bin/bash
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#   proxy and IMAP/POP3 proxy server
#
# processname: nginx
# config:  /etc/nginx/nginx.conf
# pidfile: /var/run/nginx/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/nginx.lock  
start() {
  [ -x $nginx ] || exit 5
  [ -f $NGINX_CONF_FILE ] || exit 6
  echo -n $"Starting $prog: "
  daemon $nginx -c $NGINX_CONF_FILE
  retval=$?
  echo
  [ $retval -eq 0 ] && touch $lockfile
  return $retval
}
stop() {
  echo -n $"Stopping $prog: "
  killproc $prog -QUIT
  retval=$?
  echo
  [ $retval -eq 0 ] && rm -f $lockfile
  return $retval
}
restart() {
  configtest || return $?
  stop
  sleep 1
  start
}
reload() {
  configtest || return $?
  echo -n $"Reloading $prog: "
  killproc $nginx -HUP
  RETVAL=$?
  echo
}
force_reload() {
  restart
}
configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
  status $prog
}
rh_status_q() {
  rh_status >/dev/null 2>&1
}
case "$1" in
  start)
    rh_status_q && exit 0
    $1
    ;;
  stop)
    rh_status_q || exit 0
    $1
    ;;
  restart|configtest)
    $1
    ;;
  reload)
    rh_status_q || exit 7
    $1
    ;;
  force-reload)
    force_reload
    ;;
  status)
    rh_status
    ;;
  condrestart|try-restart)
    rh_status_q || exit 0
      ;;
  *)
    echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
    exit 2
esac


chmod +x /etc/init.d/nginx
groupadd -r nginx
useradd -r -g nginx nginx


5.开启debug测试功能(前提是需要加入--with-debug编译选项)
vim /etc/nginx/nginx.conf


测试环境打开debug:
error_log  /data/logs/error.log  debug;
生产环境：
error_log  /data/logs/error.log  info;
access_log  /data/logs/access.log;


6.启动服务
/usr/sbin/nginx -c /etc/nginx/nginx.conf


/usr/sbin/nginx -V 
显示详细编译信息
configure arguments: --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx/nginx.pid --with-pcre --with-http_gzip_static_module --with-http_ssl_module --with-http_realip_module --with-http_geoip_module --add-module=../nginx_upstream_check_module-master --add-module=../ngx_cache_purge-2.3 --add-module=../ngx_devel_kit-master/ --add-module=../lua-nginx-module-master/ --with-http_stub_status_module




重新编译需要删除的文件：
rm -rf /usr/local/nginx/
rm -rf /etc/nginx/
rm -rf /var/run/nginx/


关于debug日志的说明：
一般来讲，Nginx 的错误日志级别是 error，作为 Nginx 用户来讲，你设置成 info 就足够用了。
        但有时有些难以挖掘的 bug，需要看到更详细的 debug 级别的日志，这时候，单单把 error_log 级别设置成 debug 是不行的，Nginx 记录下来的还是 info 级别以上的信息。你需要激活 Nginx 的 debug 日志才可以得到 debug 级别的日志信息。本文简要介绍了 Nginx debug 日志的激活和配置使用。官方正文如下：
        要激活 debug 日志，Nginx 在构建时需要配置为支持 debug：
./configure --with-debug ...
        然后可以通过 error_log 指令设置 debug 级别：
error_log /path/to/log debug;
        Windows 下的 Nginx 的二进制版本一般都支持 debug 日志，因此只需设置 debug 级别即可。
        注意如果你重新指定日志时没有配置 debug 级别的话，将会禁用 debug 日志。在下面的例子中，在 server 层面上重新指定的日志将会禁用这台服务器的 debug 日志：
error_log /path/to/log debug;


http {
    server {
        error_log /path/to/log;
        ...
        为了避免这种现象的发生，要么你就注释掉重新定义的那行日志，要么你就在那行也加上 debug 级别：
error_log /path/to/log debug;




http {
    server {
        error_log /path/to/log debug;
        ...
        也可以只为特定的客户端地址发来的请求开启 debug 日志：
error_log /path/to/log;




events {
    debug_connection 192.168.1.1;
    debug_connection 192.168.10.0/24;
}

附带一份nginx的参数：
