获取源码包并解压

登录http://nginx.org/en/download.html

wget http://nginx.org/download/nginx-1.20.2.tar.gz
tar -zxvf nginx-1.20.2.tar.gz

安装Nginx

cd nginx-1.20.2
./configure

make
make install

启动与退出

直接执行Nginx二进制程序

/usr/local/nginx/sbin/nginx

读取默认路径下的配置文件

cat /usr/local/nginx/conf/nginx.conf

优雅退出

/usr/local/nginx/sbin/nginx -s quit

脚本控制nginx启动和退出以及更新

nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
# nginx退出后该文件自动删除
nginx_pid=/usr/local/nginx/logs/nginx.pid
res=0
prog="nginx"

# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network

# 确认网络已经开启
[ ${NETWORKING} = "yes" ] || exit 0
# 确认nginx二进制文件有可执行权限
[ -x $nginxd ] || exit 0

        echo
        [ $res = 0 ] && rm -f /var/lock/subsys/nginx
}
# reload nginx service functions.
reload() {
    echo -n $"Reloading $prog: "
    killproc $nginxd -HUP
    res=$?
    echo
