Nginx-基本安装
1.安装编译工具及库文件
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
2.安装PCRE
PCRE的作用是让Nginx支持Rewrite功能。
- 下载PCRE安装包
cd /opt
wget https://nchc.dl.sourceforge.net/project/pcre/pcre/8.44/pcre-8.44.tar.gz --no-check-certificate
- 解压安装包
tar zxvf pcre-8.44.tar.gz
- 进入安装包目录
cd pcre-8.44
- 编译安装
./configure
make && make install
- 查看pcre版本
pcre-config --version
3.安装Nginx
nginx网址（如果文档中下载的版本有问题可自行下载新版）：
https://nginx.org/en/download.html
- 下载Nginx
cd /opt
wget https://nginx.org/download/nginx-1.24.0.tar.gz
- 解压安装包
tar zxvf nginx-1.24.0.tar.gz
- 进入解压后文件目录
cd nginx-1.24.0
- 编译安装（注意命令中–prefix=后跟的路劲为nginx编译安装后的服务器文件目录，–with-pcre=后的路劲为安装pcre的目录）
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/opt/pcre-8.44
make && make install
- 查看Nginx版本
/usr/local/webserver/nginx/sbin/nginx -v
4.Nginx配置
- 创建Nginx运行使用的用户nginx
groupadd nginx
useradd -g nginx nginx
chown -R nginx:nginx /usr/local/webserver/nginx
- 配置nginx.conf
#user nobody;
user nginx nginx; #定义运行的用户和组
worker_processes 1; #进程数，建议与CPU数相同#error_log logs/error.log;
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #设置日志位置和日志级别，由高到低，[ debug | info | notice | warn | error | crit ]#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;
pid /usr/local/webserver/nginx/nginx.pid; #进程pid文件worker_rlimit_nofile 65535; #指定进程可以打开的最多文件数目events {#use epoll; #参考事件模型，use [ kqueue | rtsig | epoll | /dev/poll | select | poll ],建议使用epollworker_connections 1024; #单个进程的最大连接数

- 检查配置文件nginx.conf的正确性命令
/usr/local/webserver/nginx/sbin/nginx -t
5.启动Nginx
- 启动
/usr/local/webserver/nginx/sbin/nginx
- 查看状态
ps -ef|grep nginx
6.访问站点
http://172.30.250.21/
7.Nginx的其他常用命令
/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
