Nginx 安装配置¶

Nginx("engine x")是一款是由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和反向代理服务器，也是一个 IMAP/POP3/SMTP 代理服务器。在高连接并发的情况下，Nginx是Apache服务器不错的替代品。 Nginx 安装系统平台：CentOS release 6.6 (Final) 64位。一、安装编译工具及库文件 yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel 二、首先要安装 PCRE PCRE 作用是让 Nginx 支持 Rewrite 功能。 1、下载 PCRE 安装包 wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz 2、解压安装包: tar zxvf pcre-8.35.tar.gz 3、进入安装包目录 cd pcre-8.35 4、编译安装 ./configure make && make install 5、查看pcre版本 pcre-config --version

安装 Nginx 1、下载 Nginx wget http://nginx.org/download/nginx-1.6.2.tar.gz 2、解压安装包 tar zxvf nginx-1.6.2.tar.gz 3、进入安装包目录 cd nginx-1.6.2 4、编译安装 ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35 make make install 5、查看nginx版本 /usr/local/webserver/nginx/sbin/nginx -v 到此，nginx安装完成。

Nginx 配置创建 Nginx 运行使用的用户 www： /usr/sbin/groupadd www /usr/sbin/useradd -g www www 配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容 cat /usr/local/webserver/nginx/conf/nginx.conf

user www www; worker_processes 2; #设置值和CPU核心数一致 error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别 pid /usr/local/webserver/nginx/nginx.pid;

Specifies the value for maximum file descriptors that can be opened by this process.¶

    }
    access_log off;
  }

}

检查配置文件nginx.conf的正确性命令： /usr/local/webserver/nginx/sbin/nginx -t

启动 Nginx Nginx 启动命令如下： /usr/local/webserver/nginx/sbin/nginx

访问站点从浏览器访问我们配置的站点ip：

Nginx 其他命令以下包含了 Nginx 常用的几个命令： /usr/local/webserver/nginx/sbin/nginx -s reload # 重新载入配置文件 /usr/local/webserver/nginx/sbin/nginx -s reopen # 重启 Nginx /usr/local/webserver/nginx/sbin/nginx -s stop # 停止 Nginx

编译安装¶

安装编译环境 APT apt-get install build-essential apt-get install libtool YUM yum -y install gcc automake autoconf libtool make yum install gcc gcc-c++ 选定源码目录 cd /usr/local/src 编译安装PCRE（rewrite），zlib（压缩）和openssl（https） PCRE wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.42.tar.gz # 不是pcre2 或 curl -O ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.42.tar.gz tar -zxvf pcre-8.42.tar.gz cd pcre-8.42 ./configure # 检测你的安装平台的目标特征，创建Makefile make # 编译 make install # 安装到指定位置

ZLIB cd /usr/local/src wget https://jaist.dl.sourceforge.net/project/libpng/zlib/1.2.11/zlib-1.2.11.tar.gz tar -zxvf zlib-1.2.11.tar.gz cd zlib-1.2.11 ./configure make make install

SSL cd /usr/local/src wget https://www.openssl.org/source/openssl-1.1.1a.tar.gz tar -zxvf openssl-1.1.1a.tar.gz

安装nginx cd /usr/local/src wget http://120.52.51.15/nginx.org/download/nginx-1.15.8.tar.gz tar -zxvf nginx-1.15.8.tar.gz cd nginx-1.15.8 sudo ./configure --sbin-path=/usr/local/nginx/nginx \ --conf-path=/usr/local/nginx/nginx.conf \ --pid-path=/usr/local/nginx/nginx.pid \ --with-http_ssl_module \ --with-pcre=/usr/local/src/pcre-8.42 \ --with-zlib=/usr/local/src/zlib-1.2.11 \ --with-openssl=/usr/local/src/openssl-1.1.1a make make install

安装完成验证启动 sudo /usr/local/nginx/nginx

停止 sudo /usr/local/nginx/nginx -s stop 或 ps -aux |grep nginx # 查找nginx进程或ps -ef kill -9 [PID] # nginx的PID进程号或 netstat -apn |grep 80 # 查找80端口占用 kill -9 [PID] # nginx的PID进程号或 sudo /usr/local/nginx/nginx -s quit 或 killall nginx

查看端口号占用 ntestat -tlnp # t查看TCP，l查看监听服务，n不解析名称，p端口号

注意firewalld放行端口帮助 sudo /usr/local/nginx/nginx -h

后续操作¶

添加到环境变量 ln -s /usr/local/nginx/nginx /usr/local/sbin/nginx # 添加软连接（快捷方式）此时可以在任意目录以nginx命令运行程序

配置文件¶

启动启动代码格式：nginx安装目录地址 -c nginx配置文件地址例如： $ /usr/local/nginx/nginx -c /usr/local/nginx/nginx.conf

检查配置文件的正确性 sudo /usr/local/nginx/nginx -t

添加服务¶

nginx一般启动 sudo /usr/local/nginx/nginx

向/etc/init.d/添加启动文件 touch nginx 添加启动脚本 NGINX Init Scripts | NGINX centos7 记得修改脚本里的路径 vim /etc/init.d/nginx 修改PATH和DAEMON路径 PATH=/usr/bin:/usr/sbin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/usr/local/nginx/nginx 给脚本添加运行权限 sudo chmod +x /etc/init.d/nginx

守护进程重载（关键步骤） systemctl daemon-reload
