编译安装nginx出现报错，以及启动nginx服务时80端口被占用怎么解决？

Posted 2020-12-04

1.准备基础环境
[[email protected] ~]# yum -y install gcc gcc-c++ make wget

---

2.解压源码包，进入目录
[[email protected] ~]# tar xf nginx-1.12.2.tar.gz
[[email protected] ~]# cd nginx-1.12.2
[[email protected] nginx-1.12.2]#

---

3.配置相关的选项，并生产Makefile
[[email protected] nginx-1.12.2]# ./configure --help|head

--help print this message

--prefix=PATH set installation prefix
--sbin-path=PATH set nginx binary pathname
--modules-path=PATH set modules path
--conf-path=PATH set nginx.conf pathname
--error-log-path=PATH set error log pathname
--pid-path=PATH set nginx.pid pathname
--lock-path=PATH set nginx.lock pathname

---

验证，是0则成功
[[email protected] nginx-1.12.2]# echo $?
0

---

4.指定编译参数
[[email protected] nginx-1.12.2]# ./configure --prefix=/opt/nginx-1.12.2
[[email protected] nginx-1.12.2]# echo $?
0

在这里，按一次补全所有，解决报错。安装完后再次指定编译即可

：yum -y install openssl-devel  

[[email protected] nginx-1.12.2]# ./configure --prefix=/opt/nginx-1.12.2

---

5.编译安装
[[email protected] nginx-1.12.2]# make
[[email protected] nginx-1.12.2]# make install
echo $?

---

6.建立软连接
[[email protected] nginx-1.12.2]# ln -s /opt/nginx-1.12.2 /opt/nginx

[[email protected] nginx-1.12.2]# /opt/nginx/sbin/nginx 启动服务

如80端口被占用，一般是httpd仓库导致
使用 killall httpd 命令，杀掉进程即可

---

5.使用ps命令查看 nginx 服务
ps -ef|grep nginx

---

6.使用ss 命令查看nginx端口是否起来
ss -anlt
