nginx笔记.

安装：

依赖的软件包：

gcc gcc-c++ autoconf automake
zlib zlib-devel openssl opensll-devel pcre pcre-devel

到官方网站上下载nginx包：

解压:

tar -zxf nginx-x.x.tar.gz

安装三步走：./configure------- make------make install

./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx 
--error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx/nginx.pid 
--lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module 
--with-http_gzip_static_module --with-http_ssl_module --http-log-path=/var/log/nginx/access.log 
--http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/
 --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ 

[root@localhost ~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf   启动nginx

查看nginx是否启动：

[root@localhost ~]# lsof -i:80
COMMAND  PID  USER   FD   TYPE DEVICE SIZE NODE NAME
nginx   7802  root    6u  IPv4  22039       TCP *:http (LISTEN)

/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf #检查配置文件的正确性。

nginx.conf 配置文件定义：

events {
    worker_connections  1024; #允许最大连接数

}

1.从容停止nginx（nginx启动停止由其pid决定）：

kill -QUIT nginx主进程号
kill -QUIT 7802 或者 kill -QUIT `cat /var/run/nginx/nginx.pid`

2.快速停止nginx：

kill -TERM ngixID 或者 kill -INT nginxID   nginxID-----主进程号
[root@localhost ~]# kill -TERM 7886
[root@localhost ~]# 
[root@localhost ~]# ps -ef | grep nginx
root      7900  3696  0 10:04 pts/3    00:00:00 grep nginx

3.强制停止nginx：

pkill -9 nginx

4.平滑启动nginx：

kill -HUP nginxID

Nginx信号控制说明：

TERM,INT 快速关闭nginx
QUIT 从容关闭；
HUP 平滑启动；
USR1 重新打开日志文件（日志切割很有用）
USR2  平滑升级可执行程序。
WINCH  从容关闭工作。升级新版本关闭旧版本时用WINCH。

检查nginx配置文件的正确与否：

/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
[root@localhost ~]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost ~]#
