centos6.5主机安装Nginx设置服务和开机自启的方法

ssh -t 用户名@主机IP或者域名 -p 22
<!--用户名一般是root，方便操作，我的登录代码如下-->
ssh -t root@acheng1314.cn -p 22

<!--切换到安装目录下-->
cd /usr/src
<!--创建Nginx文件夹用来存放Nginx相关的资源和依赖-->
mkdir Nginx
<!--下载资源和依赖-->
yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel 
<!--上面的命令一般来说会是不需要安装什么，不过这都不重要，我们接着会重新安装指定的版本-->
<!--下载pcre-->
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz
<!--解压-->
tar -zxvf pcre-8.40.tar.gz
<!--切换到pcre目录-->
cd pcre-8.40
<!--设置-->
./configure
<!--编译-->
make
<!--安装-->
make install
<!--切换到Nginx主目录-->
cd ..
<!--下载及安装zlib-->
wget http://zlib.net/zlib-1.2.11.tar.gz
<!--解压-->
tar -zxvf zlib-1.2.11.tar.gz
<!--切换到zlib目录-->
cd zlib-1.2.11
<!--设置、编译、安装-->
./configure
make
make install

<!--切换到Nginx主目录-->
cd ..
<!--下载及准备ssl-->
wget http://www.openssl.org/source/openssl-fips-2.0.14.tar.gz
<!--解压-->
tar -zxvf openssl-fips-2.0.14.tar.gz
<!--yum安装ssl-->
yum -y install openssl openssl-devel
<!--下载及安装nginx-->
wget http://nginx.org/download/nginx-1.4.2.tar.gz
tar -zxvf nginx-1.4.2.tar.gz
cd nginx-1.4.2
<!--设置Nginx安装目录/opt/nginx，且添加ssl支持-->
./configure --prefix=/opt/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre
make
make install

<!--切换到nginx设置目录-->
cd /opt/nginx/conf
<!--vim编辑nginx配置文件-->
vi nginx.conf

#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid    logs/nginx.pid;

  worker_connections 1024;

  #         '$status $body_bytes_sent "$http_referer" '
  #         '"$http_user_age

<!--检查我们的设置是否正确，正确或者错误都有对应的提示-->
/opt/nginx/sbin/nginx -t
<!--配置正确，则启用nginx-->
/opt/nginx/sbin/nginx
<!--重新载入配置文件-->
/opt/nginx/sbin/nginx -t
<!--当然到了这里的时候肯定还不能通行，毕竟我们防火墙还把443端口拦截的，所以接着走起来。-->
<!--添加443端口到防火墙-->
/sbin/iptables -I INPUT -p tcp --dport 443 -j ACCEPT
<!--保存防火墙配置-->
/etc/rc.d/init.d/iptables save
<!--是配置文件生效-->
/etc/init.d/iptables status
