Installation command:

yum -y install gcc pcre-devel zlib-devel openssl openssl-devel

nginx download address: https://nginx.org/download/

Download "nginx-1.9.9.tar.gz" and move it to /usr/local/.

## 解压
tar -zxvf nginx-1.9.9.tar.gz
##进入nginx目录
cd nginx-1.9.9
## 配置
./configure --prefix=/usr/local/nginx
# make
make
make install

OK, now you can execute make.

Execute make and make install commands

Test whether the installation is successful

# cd到刚才配置的安装目录/usr/loca/nginx/
./sbin/nginx -t

Error message:

nginx: [alert] could not open error log file: open() "/usr/local/nginx/logs/error.log" failed (2: No such file or directory)
2016/09/13 19:08:56 [emerg] 6996#0: open() "/usr/local/nginx/logs/access.log" failed (2: No such file or directory)

Cause analysis: There is no logs folder in the nginx/ directory

Solution:

mkdir logs
chmod 700 logs

Normal information output:

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

Start nginx

cd /usr/local/nginx/sbin
./nginx //启动nginx

Enter the server's IP address in the browser, such as: 192.168.1.12

Unfortunately, the link cannot be opened. Let’s troubleshoot the cause:

It means that port 80 of the server cannot be opened.

Because the Linux system version I am using is CentOS7, I can execute the following command on the server to verify》》

firewall-cmd --query-port=80/tcp

Obviously port 80 is not open.

Next we open port 80:

firewall-cmd --add-port=80/tcp --permanent
#重启防火墙
systemctl restart firewalld

--permanent #Effective permanently, without this parameter it will become invalid after restarting

Refresh the browser
