Linux7-nginx运行环境编译安装及配置

  • 安装环境(centos7)

centos 3.10.0-957.1.3.el7.x86_64

  • 安装nginx所需要的依赖库
yum -y install gcc-c++ zlib-devel openssl-devel pcre-devel
  • 下载nginx源码并解压然后进入解压目录.(源码去官网下载, 以下是官方链接)
    wget -c http://nginx.org/download/nginx-1.15.8.tar.gz
    tar -zxvf nginx-1.15.8.tar.gz
    cd nginx-1.15.8
  • 建立nginx用户及用户组
    groupadd -r nginx
    useradd  -s /sbin/nologin -g nginx -r nginx
  • 配置安装环境
./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_addition_module --with-http_flv_module --with-http_gzip_static_module --with-http_realip_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_dav_module --with-http_v2_module
#注:这里--with开头的选项为nginx自带的模块,需要什么就添加,默认是不安装,
  • 编译安装
make && make install
  • 启动nginx
/usr/local/nginx/sbin/nginx
  • 修改nginx.conf配置文件
vi /usr/local/nginx/conf/nginx.conf

#user  nobody; #把前面的#号去掉,把nobody修改为上面建立的用户名:nginx
worker_processes  1;#cpu几个线程,一般修改为几。

#error_log  logs/error.log; #去掉前面#,开启错误日志    
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

}
  • 重新加载nginx.conf配置文件
/usr/local/nginx/sbin/nginx -s reload
  • nginx添加开机启动
chmod +x /etc/rc.d/rc.local  #给予执行权限
echo "/usr/local/nginx/sbin/nginx" >>/etc/rc.local #设置开机启动
  • 检查nginx启动是否正常,我这里CPU是双线程,所以有二个工作线程
[root@localhost ~]# ps ax | grep nginx
 3396 ?        Ss     0:00 nginx: master process /usr/local/nginx/sbin/nginx
13657 ?        S      0:10 nginx: worker process
13658 ?        S      0:11 nginx: worker process
16189 pts/0    S+     0:00 grep --color=auto nginx

启动后,我们输入服务器的公网IP,就可以正常打开nginx的默认欢迎页面,若是启动正常了,就是网站打不开,那就看下防火墙( firewalld )是否开启了80端口或是http服务
