centos7下源码安装nginx

1、下载nginx，并上传到服务器上

下载好的文件通过FTP上传至 /usr/src 下

2、安装nginx依赖包

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

3、解压nginx并编译安装

[root@localhost src]# cd /usr/src
[root@localhost src]# tar -zxvf nginx-1.16.1.tar.gz
[root@localhost src]# cd nginx-1.16.1
[root@localhost nginx-1.16.1]# ./configure --prefix=/usr/local/nginx
[root@localhost nginx-1.16.1]# make && make install

4、检查配置文件时否正确、查看版本

[root@localhost nginx-1.16.1]# /usr/local/nginx/sbin/nginx -t
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

　　返回OK,successful,说明成功

　　查看nginx版本

[root@localhost nginx-1.16.1]# /usr/local/nginx/sbin/nginx -V　

至此编译安装已完成

5、启动

[root@localhost etc]# /usr/local/nginx/sbin/nginx                   #启动
[root@localhost etc]# /usr/local/nginx/sbin/nginx -s reload     #重载
[root@localhost etc]# /usr/local/nginx/sbin/nginx -s stop        #停止
    

[root@localhost nginx-1.16.1]# /usr/local/nginx/sbin/nginx #按下ENTER键运行nginx 
ps -A | grep nginx 或 ps -ef | grep nginx #查看nginx是否运行

[root@localhost nginx-1.16.1]# /usr/local/nginx/sbin/nginx
[root@localhost nginx-1.16.1]# ps -A | grep nginx
 6807 ?        00:00:00 nginx
 6808 ?        00:00:00 nginx

　　

[root@localhost nginx-1.16.1]# /usr/local/nginx/sbin/nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

　提示有问题80端口已被监听

解决办法

 先关闭nginx

6、把nginx加到开机启动中

　　在/etc/init.d下创建文件nginx

　　vim /etc/init.d/nginx

需要注意的配置：

　　nginx="/usr/local/nginx/sbin/nginx" #修改成nginx执行程序的路径。

　　NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" #修改成nginx.conf文件的路径。

 保存后设置文件的执行权限

　　chmod a+x /etc/init.d/nginx

至此就可以通过下面指令控制启动停止

　　/etc/init.d/nginx start
　　/etc/init.d/nginx stop

上面的方法完成了用脚本管理nginx服务的功能，但是还是不太方便。

先将nginx服务加入chkconfig管理列表：

[root@localhost conf]# chkconfig --add /etc/init.d/nginx
service nginx does not support chkconfig

nginx服务不支持chkconfig

需在vim /etc/init.d/nginx后加入

# chkconfig: 2345 85 15
# description: Nginx is a World Wide Web server.

#号不要删，重新运行没有输出，就没有问题

[root@localhost init.d]# chkconfig --add /etc/init.d/nginx

加完这个之后，就可以使用service对nginx进行启动，重启等操作了。

service nginx start
service nginx stop
service nginx restart

最后设置开机自动启动

chkconfig nginx on

　支持 systemctl服务的，参考https://blog.csdn.net/qq_21437451/article/details/82530057
