目录
5.默认会安装在/usr/local/nginx这里通过configure命令指定安装目录
前言
最近斥巨资买了台服务器现记录下nginx安装配置过程。
一、下载安装解压
1.进入临时文件夹里随便一个都行
cd /tmp/2.下载并安装nginx压缩包
wget http://nginx.org/download/nginx-1.23.3.tar.gz3.解压该压缩包
tar -xvf nginx-1.23.3.tar.gz4.创建目标文件夹
cd /tmp/nginx-1.23.35.默认会安装在/usr/local/nginx这里通过configure命令指定安装目录
./configure --prefix=/data/nginx6.编译安装
make && make install7.最后生成的文件夹具体如下
二、运行
1.进入nginx下的sbin目录
cd /data/nginx/sbin2.执行启动
./nginx3.查看nginx是否启动
ps -ef | grep nginx 
4.浏览器访问你的IP如下就是成功了
三、卸载
1.查看nginx是否运行
ps aux | grep nginx2.进入nginx下的sbin目录
cd /data/nginx/sbin3.停止nginx运行
./nginx -s stop4.查看与Nginx有关的文件夹
find / -name nginx5.删除与Nginx有关的文件
rm -rf file /data/nginx*6.再查看
find / -name nginx*7.卸载Nginx的依赖
yum remove nginx
四、Nginx的基本操作命令
1.进入nginx下的sbin目录
cd /data/nginx/sbin2.启动
./nginx3.关闭
./nginx -s stop4.重启
./nginx -s reload
五、配置成系统服务
1.创建nginx.service文件
vim /usr/lib/systemd/system/nginx.service
2.nginx.service文件中写入内容
[Unit]
Description=nginx web service
Documentation=http://nginx.org/en/docs/
After=network.target
[Service]
Type=forking
PIDFile=/data/nginx/nginx/logs/nginx.pid
ExecStartPre=/data/nginx/nginx/sbin/nginx -t -c /data/nginx/nginx/conf/nginx.conf
ExecStart=/data/nginx/nginx/sbin/nginx
ExecReload=/data/nginx/nginx/sbin/nginx -s reload
ExecStop=/data/nginx/nginx/sbin/nginx -s stop
PrivateTmp=true
[Install]
WantedBy=default.target3.改权限
chmod 755 /usr/lib/systemd/system/nginx.service4.文件生效
systemctl daemon-reload
5.设置开机自启
systemctl enable nginx.service
六、系统服务操作Nginx基本命令
1.启动
systemctl start nginx2.停止
systemctl stop nginx3.重启
systemctl restart nginx4.重新加载配置文件
systemctl reload nginx5. 查看Nginx状态
systemctl status nginx6.开机自动
systemctl enable nginx七、nginx.conf文件基本配置详解
