一、安装依赖包
yum install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre-devel
二、下载
cd /usr/local/src/
wget http://nginx.org/download/nginx-1.14.2.tar.gz
三、编译
tar -zxvf nginx-1.14..tar.gz
cd nginx-1.14.
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
四、将nginx设置为服务
centos 7 中采用 systemd 来管理系统，我们为 nginx 创建服务文件
vim /lib/systemd/system/nginx.service
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
这里的 PIDFile 的配置要和前面的 配置保持一致。
设置自启动
[root@node2 logs]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
五、启动nginx
[root@node2 logs]# systemctl start nginx
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
提示报错，查看查看状态
[root@node2 logs]# systemctl status nginx

提示80端口被占用，此时执行：
[root@node2 sbin]# killall - nginx
-bash: killall: 未找到命令
安装killall
yum install psmisc
再执行
killall - nginx
启动服务
[root@node2 sbin]# systemctl start nginx
[root@node2 sbin]#
没有报错，查看状态
[root@node2 sbin]# systemctl status nginx

获取页面成功
建立软连接
ln -s /usr/local/nginx/sbin/nginx /usr/sbin/
此时nginx可以在任意目录下执行命令
