Linux环境下(CentOS 7)安装/卸载nginx及配置系统服务_删除nginx的系统服务

一、安装nginx

1、安装所需的依赖

1. # 安装gcc
2. yum install gcc-c++
4. # 安装PCRE pcre-devel
5. yum install -y pcre pcre-devel
6.  
7. # 安装zlib
8. yum install -y zlib zlib-devel
9.  
10. # 安装Open SSL
11. yum install -y openssl openssl-devel

2、下载nginx稳定版

nginx官网下载
http://nginx.org/en/download.html
http://nginx.org/download/

1. cd /home/
2. # 下载
    
3. wget http://nginx.org/download/nginx-1.23.2.tar.gz
4. # tar zxvf 命令进行解压
5. tar zxvf nginx-1.23.2.tar.gz
6. # 重命名 nginx-1.23.2文件夹
7. mv nginx-1.23.2 nginx

3、编译&安装

 # 进入nginx目录，默认安装目录：/usr/local/nginx(进入nginx文件夹，运行configure脚本)
cd /home/nginx/ 
# 执行命令 （默认会安装在/usr/local/nginx）这里通过configure命令指定安装目录
./configure --prefix=/webnginx
# 执行make命令(要是执行不成功请检查最开始安装的四个有没有安装成功)
# 执行make install命令
make && make install
# 查看编译参数命令
./configure --help | more

最后生成的文件夹具体如下

4、启动nginx

1.进入nginx下的sbin目录

cd /webnginx/sbin

2.执行启动

./nginx

3.查看nginx是否启动

ps -ef | grep nginx

4.浏览器访问你的IP

二、卸载nginx

1.查看nginx是否运行
ps aux | grep nginx

2.进入nginx下的sbin目录
cd /webnginx/sbin

3.停止nginx运行
./nginx -s stop

4.查看与Nginx有关的文件夹
find / -name nginx

5.删除与Nginx有关的文件
rm -rf file /webnginx*

6.再查看
find / -name nginx*

7.卸载Nginx的依赖
yum remove nginx
 

三、Nginx操作命令

1.进入nginx下的sbin目录

cd /webnginx/sbin

2.启动

./nginx

3.关闭 

./nginx -s stop

4.重启 

./nginx -s reload

四、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=/webnginx/logs/nginx.pid
ExecStartPre=/webnginx/sbin/nginx -t -c /webnginx/conf/nginx.conf
ExecStart=/webnginx/sbin/nginx
ExecReload=/webnginx/sbin/nginx -s reload
ExecStop=/webnginx/sbin/nginx -s stop
PrivateTmp=true
 
[Install]
WantedBy=default.target
 
 
3.改权限
chmod 755 /usr/lib/systemd/system/nginx.service
 
4.文件生效  
systemctl daemon-reload
 
5.设置开机自启 
systemctl enable nginx.service 
 

五、系统服务Nginx基本命令

1.启动
systemctl start nginx
 
2.停止
systemctl stop nginx
 
3.重启
systemctl restart nginx
 
4.重新加载配置文件
systemctl reload nginx
 
5. 查看Nginx状态
systemctl status nginx
 
6.开机自动
systemctl enable nginx

六、nginx.conf文件基本配置详解
