Nginx
Nevermore 2023-12-17 CNET
# 安装
下载 (opens new window)后解压到相应目录
安装依赖库：libz-dev libprce3-dev libssl-dev
生成安装文件（root）
./configure --prefix=path #/usr/local/nginx make make install #会将make生成的文件copy到path1
2
3将./contrib/vim文件拷贝到.vim中
# 第三方模块
拉取对应的模块，如nginx-rtmp-module (opens new window)
将模块添加到配置文件：./configure --add-dynamic-module=/ModulePath
make modules，在objs目录里有生成的文件，若有.so文件，将其拷贝到/usr/local/nginx/modules/
配置文件首行添加：load_module modules/动态库名字
# 基本使用
sbin/nginx
- -v/-V ：版本信息
- -c ：指定配置文件
- -t ：检查配置文件语法错误
- -s ：quit（优雅关闭） stop（立即关闭） reload
不能同时启动两个nginx进程，pid都会存到同一个pid_file里；若一定要启动两个，将pid打开，将两个nginx进程的pid存储到不同名字的文件，日志文件最好也修改。
# 配置文件
【1】MDN (opens new window)type查询
【3】正则匹配：location ~* /(.*)a
忽略大小写~后的*；
