# mac 下安装 nginx

brew install nginx
brew reinstall nginx
Docroot is: /usr/local/var/www
The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that nginx can run without sudo.
nginx will load all files in /usr/local/etc/nginx/servers/.
To start nginx:
  brew services start nginx
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/nginx/bin/nginx -g 'daemon off;'
==> Summary
🍺  /usr/local/Cellar/nginx/1.21.3: 26 files, 2.2MB
# Linux (Ubuntu) 下安装 nginx
安装依赖：
sudo apt install gcc
sudo apt install make
sudo apt install zlib1g-dev
sudo apt install libpcre3-dev
nginx版本和ssl版本：
openssl-3.4.0.tar.gz
nginx-1.27.2.tar.gz
# ⚠️ 特别注意事项（务必先看）
执行 ./configure 和 make install 时，尽量不要使用 sudo ，否则可能产生各种各样的权限问题。
  • sudo 执行时会以 root 身份运行，编译产物、生成目录会被 root 拥有，后续用普通用户操作（启动、改配置、写日志）会出现 Permission denied 。
  • root 用户与普通用户的环境变量、PATH、umask、HOME 都存在差异，可能导致依赖探测到不同版本、文件权限不一致等问题。
  • --prefix 等路径建议直接指向当前普通用户有权限的目录（如 /home/huruiyi/app/nginx ），这样全程无需 sudo 。
✅ 推荐做法：
# 普通用户身份执行，不要加 sudo
./configure \
    --prefix=/home/huruiyi/app/nginx \
    ...
make
make install
❌ 需要避免：
sudo ./configure ...
sudo make install
如果之前已经用 sudo 编译安装过，导致目录归属 root，可以先修正归属再重新编译：
sudo chown -R $USER:$USER /home/huruiyi/app/nginx
安装配置：
注意：不要加 sudo ，直接以当前普通用户身份执行。
./configure  \
    --prefix=/home/huruiyi/app/nginx  \
    --pid-path=/home/huruiyi/app/nginx/pid/nginx.pid  \
    --lock-path=/lock/nginx.lock  \
    --error-log-path=/home/huruiyi/app/nginx/log/error.log  \
    --http-log-path=/home/huruiyi/app/nginx/log/access.log  \
    --http-client-body-temp-path=/home/huruiyi/app/nginx/temp/client  \
    --http-proxy-temp-path=/home/huruiyi/app/nginx/temp/proxy  \
    --http-fastcgi-temp-path=/home/huruiyi/app/nginx/temp/fastcgi  \
    --http-uwsgi-temp-path=/home/huruiyi/app/nginx/temp/uwsgi  \
    --http-scgi-temp-path=/home/huruiyi/app/nginx/temp/scgi  \
    --with-http_ssl_module  \
    --with-http_gzip_static_module \
    --with-openssl=/home/huruiyi/soft/openssl-3.4.0

# nginx 启动相关命令
To start nginx, run the executable file. Once nginx is started, it can be controlled by invoking the executable with the -s parameter. Use the following syntax:

nginx -s signal
Where signal may be one of the following:

stop — fast shutdown
quit — graceful shutdown
reload — reloading the configuration file
reopen — reopening the log files

For example, to stop nginx processes with waiting for the worker processes to finish serving current requests, the following command can be executed:

nginx -s quit
This command should be executed under the same user that started nginx.
Changes made in the configuration file will not be applied until the command to reload configuration is sent to nginx or it is restarted. To reload configuration, execute:

nginx -s reload
Once the master process receives the signal to reload configuration, it checks the syntax validity of the new configuration file and tries to apply the configuration provided in it. If this is a success, the master process starts new worker processes and sends messages to old worker processes, requesting them to shut down. Otherwise, the master process rolls back the changes and continues to work with the old configuration. Old worker processes, receiving a command to shut down, stop accepting new connections and continue to service current requests until all such requests are serviced. After that, the old worker processes exit.

A signal may also be sent to nginx processes with the help of Unix tools such as the kill utility. In this case a signal is sent directly to a process with a given process ID. The process ID of the nginx master process is written, by default, to the nginx.pid in the directory /usr/local/nginx/logs or /var/run. For example, if the master process ID is 1628, to send the QUIT signal resulting in nginx’s graceful shutdown, execute:

kill -s QUIT 1628
For getting the list of all running nginx processes, the ps utility may be used, for example, in the following way:

ps -ax | grep nginx
