Installation and Startup of nginx

Installation: reference link - Novice bird tutorial
Start:

find / -name nginx
/usr/local/nginx/sbin/nginx
ps -ef|grep nginx

Configure nginx startup self-start:

vim /etc/rc.d/rc.local

touch /var/lock/subsys/local
/usr/bin/fdfs_tracked /etc/fdfs/tracker.conf restart
/usr/bin/fdfs_storaged /etc/fdfs/storage.conf restart
/usr/local/nginx/sbin/nginx

Open log for nginx

I have a configuration like this
location /test {
alias /home/lmj/;
index test.html;
}

View error log:
vim /usr/local/nginx/logs/error.log
"/home/lmj/" failed (13: Permission denied)
Open access to resources
chmod 777 /home/lmj chmod 777 /home/lmj/test.html
Specify the installation directory for nginx at installation time
./configure --prefix=/xx/xx

–with-debug enable debug logging
–modules-path=PATH set modules path
–with-select_module enable select module
–without-select_module disable select module

@RequestMapping("testRedisson")

Browser access http://192.168.43.14/testRedisson
With load balancing, requests are randomly assigned to ports 8082, 8083, 8084, with the following forwarded paths:
http://192.168.43.107:8082/testRedisson
http://192.168.43.107:8083/testRedisson
