1.nginx安装

1.安装nginx环境

uname -aLinux localhost.localdomain 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

2.安装nginx需提前安装的软件

#查询软件安装目录rpm -qarpm -ql xxxxxxxxxxx#安装gcc编译器yum -y install gcc#nginx使用到正则表达式的话必须安装的软件，用于解析正则表达式。默认安装在 /usr/lib64/yum -y install pcre pcre-devel#安装zlib。用于响应体重压缩gzib。默认安装 /usr/lib64/yum -y install zlib zlib-devel#安装openssl。安装目录 /usr/lib64/opensslyum -y install openssl oepnssl-devel /usr/lib64/

3.安装nginx

cd ~mkdir softcd  softwget http://nginx.org/download/nginx-1.11.4.tar.gztar -zxvf nginx-1.11.4.tar.gz cd nginx-1.11.4./configure --prefix=/usr/local/nginxmakemake install

4.修改nginx配置

cd /usr/local/nginx/cd conf/vi ./nginx.conf

nginx 配置

5.启动,访问和停止nginx

cd ../sbin./nginxcurl http://127.0.0.1:80

6.常用命令

#启动指定配置文件/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf#指定nginx 安装目录/usr/local/nginx/sbin/nginx -p /usr/local/nginx#临时全局指定一些全局配置项。不能和已有的写在配置文件中的配置项相冲突，执行其他命令也要带上-g/usr/local/nginx/sbin/nginx -g "pid /usr/local/nginx/log/test.pid" #测试配置文件是否正确/usr/local/nginx/sbin/nginx -t#显示版本信息/usr/local/nginx/sbin/nginx -v#快速停止服务/usr/local/nginx/sbin/nginx -s stop#==等效于直接向master进程发送TERM和INT信号量ps -ef | grep nginx#显示如下进程：root       7309      1  0 19:05 ?        00:00:00 nginx: master process ./nginxnobody     7310   7309  0 19:05 ?        00:00:00 nginx: worker processroot       7405   2269  0 21:54 pts/0    00:00:00 grep --color=auto nginx#执行:kill -s SIGTERM 7309 orkill -s SIGINT 7309 #优雅的退出服务。关闭监听端口，停止接收请求。处理完目前的任务后停止服务/usr/local/nginx/sbin/nginx -s quit#==等效于直接向master进程发送QUIT信号量。#或者优雅的停止worker进程发送WINCH信号量#nginx重读配置项并生效。实际上会检查配置项，优雅的关闭，再启动服务/usr/local/nginx/sbin/nginx -s reload#==等效于直接向master进程发送HUP信号量。#日志文件回滚。重新生成日志文件，我们可以拷贝日志文件，以至于日志文件不会过大/usr/local/nginx/sbin/nginx -s reopen#==等效于直接向master进程发送USR1信号量。#平滑升级#向master进程发送USR2信号量。此时同时存在两个进程，可以手工平滑停止老进程

7.总结

无。
