# 首先安装必要的库（nginx 中gzip模块需要 zlib 库，rewrite模块需要 pcre 库，ssl 功能需要openssl库）yum install gcc-c++ -yyum install pcre pcre-devel -yyum install zlib zlib-devel -yyum install openssl openssl-devel -y
# 安装之前，最好检查一下是否已经安装有nginxfind -name nginx# 如果系统已经安装了nginx，那么就先卸载yum remove nginx# 首先进入/usr/local目录cd /usr/local# 从官网下载最新版的nginxwget http://nginx.org/download/nginx-1.17.7.tar.gz# 解压nginx压缩包tar -zxvf nginx-1.17.7.tar.gz
# 会产生一个nginx-1.17.7 目录，这时进入nginx-1.17.7目录cd nginx-1.17.7# 接下来安装，使用--prefix参数指定nginx安装的目录,make、make install安装# --prefix 指定安装目录，默认为 /usr/local/nginx# --with-http_ssl_module 启用ssl模块./configure --with-http_ssl_modulemakemake install# 如果没有报错，顺利完成后，最好看一下nginx的安装目录whereis nginx# 安装完毕后，进入安装后目录（/usr/local/nginx）便可以启动或停止它了。# 到此，使用CentOS安装nginx已经完成了，其实看看还是蛮简单的。
/usr/local/nginx/sbin/nginx# 检查是否启动成功：# 打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。# 如果运行的时候不带-c参数，那就采用默认的配置文件，即/usr/local/nginx/conf/nginx.conf# 查看运行进程状态：ps aux | grep nginx
# 部分命令如下：# 重启：/usr/local/nginx/sbin/nginx –s reload# 停止：/usr/local/nginx/sbin/nginx –s stop# 测试配置文件是否正常：/usr/local/nginx/sbin/nginx –t# 强制关闭：pkill nginx
