systemctl 启动编译安装nginx
一、通过yum安装nginx 获取nginx的启动脚本(或直接复制我下面的脚本,只需要改变路径即可)
/usr/lib/systemd/system/nginx.service
脚本内容如下:
[Unit] Description=nginx - high performance web server Documentation=http://nginx.org/en/docs/ After=network-online.target remote-fs.target nss-lookup.target Wants=network-online.target [Service] Type=forking PIDFile=/var/run/nginx.pid ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat /var/run/nginx.pid)" ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat /var/run/nginx.pid)" [Install] WantedBy=multi-user.target
二、修改路径
1、修改二进制文件路径
我这里安装的路径是:
/apps/nginx/sbin/nginx
配置文件路径是:
/apps/nginx/conf/nginx.conf
修改下面这行:
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
修改为:
ExecStart=/apps/nginx/sbin/nginx -c /apps/nginx/conf/nginx.conf
2、修改PID文件路径
## PID文件路径要和nginx配置中的路径一样,pid文件和配置文件中不一样,会导致这个脚本永不了,默认没配置,这里修改配置文件
/apps/nginx/conf/nginx.conf 取消注释pid这行
pid logs/nginx.pid;
## 这里的log是我安装目录里的logs。我安装的位置是/apps/nginx/
修改这行:
PIDFile=/var/run/nginx.pid
修改为:
PIDFile=/apps/nginx/logs/nginx.pid
[Unit] Description=nginx - high performance web server Documentation=http://nginx.org/en/docs/ After=network-online.target remote-fs.target nss-lookup.target Wants=network-online.target [Service] Type=forking PIDFile=/apps/nginx/logs/nginx.pid ExecStart=/apps/nginx/sbin/nginx -c /apps/nginx/conf/nginx.conf ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat /apps/nginx/logs/nginx.pid)" ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat /apps/nginx/logs/nginx.pid)" [Install] WantedBy=multi-user.target
## 标绿的两行,看配置模板文件版本可能需要修改,也可能不需要修改,我这里使用的是nginx/1.20.1 版的配置文件,这里的路径不修改不会影响开启和关闭,但当我Systemctl reload nginx 时候会提示错误:“Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.“”记得修改完之后systemctl daemon-reload下
三、将修改好的配置移动到:
/usr/lib/systemd/system
四、测试:
1、停止nginx服务
systemctl stop nginx
2、开启nginx服务
systemctl start nginx
3、重读nginx配置文件(会回收之前空闲的工作进程,并启动新的工作进程)
systemctl reload nginx
