06 | Nginx的版本发布历史

07 | 选择哪一个Nginx发行版本？

08 | 编译出适合自己的Nginx

下载Nginx到Linux上
http://nginx.org/en/download.html

# wget http://nginx.org/download/nginx-1.18.0.tar.gz
# cd nginx-1.18.0
# 会报错说缺少一些模块，根据报错安装对应模块
# ./configure --prefix=/root/nginx 
# yum install pcre-devel -y
# yum install zlib-devel -y
# ./configure --prefix=/root/nginx

09 | Nginx配置文件的通用语法介绍

10 | Nginx命令行及演示：重载、热部署、日志切割

让vim编辑器能显示Nginx语法：

cp  -r /root/nginx-1.18.0/contrib/vim/* ~/.vim/

启动Nginx：

./nginx

不停止服务的情况下重启：

./nginx -s reload

热部署-热升级

# cp nginx nginx.old
# cp ../nginx .   # 确认替换

# ps -ef | grep nginx
root      7744     1  0 11:44 ?        00:00:00 nginx: master process ./sbin/nginx
nobody    7745  7744  0 11:44 ?        00:00:00 nginx: worker process
root      7834  1650  0 11:56 pts/0    00:00:00 grep --color=auto nginx
# kill master进程，会启动新的master进程和work进程，但是老的不会被杀掉，流量会平滑的从老的切换到新的，老的master和worker继续存在，
# kill USE2 7744
# 使用kill -WINCH 7744优雅的关掉worker进程
# kill -WINCH 7744
# master进程还在，是为了做回退。
