Nginx

一键自动安装

CentOS 7.6

# yum 安装
yum update
yum install -y nginx

# apt-get 安装
apt-get update
apt-get install nginx

# 配置文件路径
/etc/nginx/nginx.conf
/etc/nginx/conf.d/*.conf

# 启动
systemctl start nginx

# 停止
systemctl stop nginx

# 重启
systemctl restart nginx

# 加载配置文件而不需要重启 nginx
service nginx reload

# 开机启动
systemctl enable nginx

# 各种配置，看单独的模块介绍，不再说明

配置PHP时注意

location ~ \.php(.*)$ {
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  PATH_INFO  $fastcgi_path_info;
    fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
    include        fastcgi_params;
}

# 如果 conf.d 里面有一个 php-fpm.conf 文件，里面内容如下时，需要将 127.0.0.1:9000 替换成 php-fpm

# PHP-FPM FastCGI server
# network or unix domain socket configuration

upstream php-fpm {
         server unix:/run/php-fpm/www.sock;
}

# 替换后的参数配置如下
location ~ \.php(.*)$ {
    fastcgi_pass   php-fpm;
    fastcgi_index  index.php;
    fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  PATH_INFO  $fastcgi_path_info;
    fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
    include        fastcgi_params;
}

简单配置

server {
        listen        80;
        server_name   laravel6.com;
        root   /data/www/laravel_6/public;

        location / {
            index  index.php index.html index.htm;
            if (!-e $request_filename) {
                rewrite ^(.*)$ /index.php?s=/$1 last;
            }
        }

        location ~ \.php(.*)$ {
            fastcgi_pass   php-fpm;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

一些报错

出现 403 404 等，查 nginx 日志，有这么一条 is forbidden (13: Permission denied)

一、查看文件或文件夹权限，试着给 777

二、nginx 配置文件缺少指引文件 index index.php index.html index.htm;

三、坑爹的这个 selinux，临时关闭一下 setenforce 0 关闭后如果正常，就是他的问题了

# 彻底关闭方法
vim /etc/selinux/config

# 修改 SELINUX=enforcing 改为 SELINUX=disabled

#修改后
SELINUX=enable

源码安装

# 安装必要扩展
yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

# 下载
wget http://nginx.org/download/nginx-1.18.0.tar.gz

# 解压
tar -zxvf nginx-1.18.0.tar.gz

# 进入
cd nginx-1.18.0

# 配置，其实默认执行 ./configure 即可，除非你要自定义
./configure \
--user=nginx \
--group=nginx \
--prefix=/usr/local/nginx-1.18.0 \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_gzip_static_module

# 编译 && 安装，默认安装位置 /usr/local/nginx
make
make && install

一些基本命令

# 查看版本
/usr/local/nginx/sbin/nginx -v

# 启动
/usr/local/nginx/sbin/nginx

# 重新载入配置文件
/usr/local/nginx/sbin/nginx -s reload

# 快速关闭 Nginx
/usr/local/nginx/sbin/nginx -s stop

# 关闭 Nginx
/usr/local/nginx/sbin/nginx -s quit

配置 systemctl 启动

vim  /usr/lib/systemd/system/nginx.service
输入以下内容后保存：
[Unit]
Description=nginx
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPost=/bin/sleep 0.1
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

后续启动可以用：systemctl start nginx

设置开机启动： systemctl enable nginx
