Linux下源码安装nginx服务器以及部分配置

Nginx ("engine x") 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru站点开发的，第一个公开版本0.1.0发布于2004年10月4日。其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。2011年6月1日，nginx 1.0.4发布。
Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，并在一个BSD-like 协议下发行。由俄罗斯的程序设计师Igor Sysoev所开发，供俄国大型的入口网站及搜索引擎Rambler（俄文：Рамблер）使用。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有：京东、新浪、网易、腾讯、淘宝等。

一、这里为大家演示nginx的源码安装过程：
首先是要去网上download安装所需要的软件包，这里默认为大家yum源已经配好。
1、#download nginx-1.8.1.tar.gz &&tar -zxf nginx-1.8.1.tar.gz #下载并解压软件包
2、# cd nginx-1.8.1/src/core/ #修改配置文件，这里是将版本号进行了自定义
修改配置文件nginx-1.8.1/src/core/nginx.h
#define nginx_version 1008001
#define NGINX_VERSION "1.8.1"
#define NGINX_VER "nginx/" NGINX_VERSION
修改如下所示：
#define nginx_version 1008001
#define NGINX_VERSION "1.8.1"
#define NGINX_VER "nginx/"

3、#cd auto/cc/
修改配置文件：vimauto/cc/gcc的179行文件
178 # debug
179 CFLAGS="$CFLAGS -g"
修改如下所示：
178 # debug
179 #CFLAGS="$CFLAGS -g" #将这一行注释掉

4、执行configure文件
[root@pt2 nginx-1.8.1]# ./configure--prefix=/usr/local/lnmp/nginx --with-http_ssl_module--with-http_stub_status_module #进行编译并制定目录与参数

# ./configure --prefix=/usr/local/lnmp/nginx--with-http_ssl_module --with-http_stub_status_module --add-module=/root/nginx-sticky-module-1.0 #需要sticky时加上这个参数，指向文件存放的位置

5、#make && make install

二、安装完成好以后，我们进行相关的配置：
1、首先把nginx的启动脚本路径加入到环境变量中，
# vim ~/.bash_profile
PATH:/usr/bin:/usr/sbin:/bin:/usr/local/lnmp/nginx/sbin #在这句后面加入nginx的sbin路径

# source ~/.bash_profile #把更改的文件刷新一遍就可以使用了

[root@pt1 conf]# nginx #开启nginx服务，默认端口为80，注意不要和httpd服务冲突

测试结果可以看到信息：




编辑/etc/security/limits.conf文件，增加条目 如下：




编辑nginx配置文件nginx.conf




查看系统所允许的最大数




下面是压测结果：

编辑配置文件nginx.conf
server {
listen 443 ssl; #监听端口，这里为https的请求
server_name localhost;

ssl_certificate cert.pem; #证书
ssl_certificate_key cert.pem; #钥匙

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; #默认发布页文件
}

生成自定义证书，并把它移动到/usr/local/lnmp/nginx/conf/下：
[root@pt1 conf]# cd /etc/pki/tls/certs/
[root@pt1 certs]# make cert.pem
umask 77 ; \
PEM1=`/bin/mktemp/tmp/openssl.XXXXXX` ; \
PEM2=`/bin/mktemp/tmp/openssl.XXXXXX` ; \
/usr/bin/opensslreq -utf8 -newkey rsa:2048 -keyout $PEM1 -nodes -x509 -days 365 -out $PEM2-set_serial 0 ; \
cat$PEM1 > cert.pem ; \
echo"" >> cert.pem ; \
cat$PEM2 >> cert.pem ; \
rm-f $PEM1 $PEM2
