Web - nginx安装
about
使用yum安装
centos7.9
直接yum进行安装，顺便把ab压测工具也安装了：
[root@cs ~]# yum install nginx httpd-tools -y
[root@cs ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
# 推荐使用systemctl来管理nginx
[root@cs ~]# systemctl start nginx
[root@cs ~]# lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

其他：
/var/log/nginx/access.log # nginx的日志位置
/var/log/nginx/error.log # nginx错误日志
/usr/share/nginx/ # nginx安装目录
# 压测，生成一些数据, -n表示访问多少次；-c表示多少个并发，注意，路径最后一定跟/
ab -n 100 -c 10 http://10.0.0.200/
that's all
