Nginx 安装

安装环境：CentOS Linux release 7.6
安装nginx版本：1.16.1

$cat /etc/redhat-release

CentOS Linux release 7.6.1810 (Core)

1､安装步骤

$yum install gcc-c++

$yum install -y pcre pcre-devel

$yum install -y zlib zlib-devel

$yum install -y openssl openssl-devel

$wget http://nginx.org/download/nginx-1.16.1.tar.gz

$tar -zxvf nginx-1.16.1.tar.gz -C /usr/local

$cd /usr/local/nginx-1.16.1

$./configure --prefix=/usr --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/tem/nginx/client --http-proxy-temp-path=/var/tem/nginx/proxy --http-fastcgi-temp-path=/var/tem/nginx/fcgi --with-http_stub_status_module

Configuration summary
  + using system PCRE library
  + using system OpenSSL library
  + using system zlib library

  nginx path prefix: "/usr"
  nginx binary file: "/usr/sbin/nginx"
  nginx modules path: "/usr/modules"
  nginx configuration prefix: "/etc/nginx"
  nginx configuration file: "/etc/nginx/nginx.conf"
  nginx pid file: "/var/run/nginx/nginx.pid"
  nginx error log file: "/var/log/nginx/error.log"
  nginx http access log file: "/var/log/nginx/access.log"
  nginx http client request body temporary files: "/var/tem/nginx/client"
  nginx http proxy temporary files: "/var/tem/nginx/proxy"
  nginx http fastcgi temporary files: "/var/tem/nginx/fcgi"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

$make && make install

2、启动

nginx -c /etc/nginx/nginx.conf

3、Trouble Shooting

出现[emerg] getpwnam("nginx") failed 错误

$useradd -s /sbin/nologin -M nginx
$id nginx

出现nginx: [emerg] mkdir() "/var/tem/nginx/client" failed (2: No such file or directory)

sudo mkdir -p /var/tem/nginx/client

如果您正在运行防火墙，请运行以下命令以允许HTTP和HTTPS通信

sudo firewall-cmd --permanent --zone=public --add-service=http 
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

4、重启

可选方法如下：

4.1､进入nginx可执行目录sbin下，输入命令./nginx -s reload 即可

$cd /usr/sbin
$ls -lh nginx 
$./nginx -s reload

4.2､查找当前nginx进程号，然后输入命令：kill -HUP 进程号 实现重启nginx服务

$ps -ef | grep nginx
root     18446     1  0 18:35 ?        00:00:00 nginx: master process nginx -c /etc/nginx/nginx.conf
nginx    18448 18446  0 18:35 ?        00:00:00 nginx: worker process
root     18487 13105  0 18:39 pts/2    00:00:00 grep --color=auto nginx
$kill -HUP 18446

5、停止

$cd /usr/sbin
$ls -lh nginx 
$./nginx -s stop

6、帮助

$cd /usr/sbin
$ls -lh nginx 
$./nginx -h
nginx version: nginx/1.16.1
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:

  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /usr/)
  -c filename   : set configuration file (default: /etc/nginx/nginx.conf)
  -g directives : set global directives out of configuration file

7、查看版本

$cd /usr/sbin
$ls -lh nginx 
$./nginx -v
nginx version: nginx/1.16.1
