(启动报错处理：
nginx: [alert] could not open error log file: open() "/usr/local/app/nginx-1.16.1/logs/error.log" failed (2: No such file or directory)
2021/04/15 10:26:26 [emerg] 7596#0: open() "/usr/local/app/nginx-1.16.1/logs/access.log" failed (2: No such file or directory)
)
一：安装基础工具：
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
二：安装 Nginx
地址：http://nginx.org/en/download.html
查找需要的版本，这里以1.16.1 为例：
wget https://nginx.org/download/nginx-1.16.1.tar.gz
解压：
tar -zxvf nginx-1.16.1.tar.gz
cd nginx-1.16.1
./configure
./configure --prefix=/usr/local/app/nginx (指定安装目录)
make
make install
启动nginx
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf (最安全的启动方式）
或者
cd /usr/local/nginx/sbin/
./nginx
./nginx -s stop # 此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程。
./nginx -s quit # 此方式停止步骤是待nginx进程处理任务完毕进行停止。
./nginx -s reload #启动
重启Nginx （cd /usr/local/nginx/sbin)
./nginx -s quit
./nginx
设置开机自启动：
即在rc.local增加启动代码就可以了。
vi /etc/rc.local
增加一行 /usr/local/nginx/sbin/nginx
设置执行权限：
chmod 755 rc.local
