https://blog.csdn.net/qq_36454337/article/details/81136775 1、安装依赖包 [root@host-10-1-1-161 ~]# yum -y install gcc gcc-c++ autoconf automake [root@host-10-1-1-161 ~]# yum -y install zlib zlib-devel openssl openssl-devel pcre-devel [root@host-10-1-1-161 ~]# yum -y install gcc automake autoconf libtool gcc-c++ gd zlib zlib-devel openssl openssl-devel libxml2 libxml2-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libmcrypt libmcrypt-devel pcre pcre-devel 2、安装nginx [root@host-10-1-1-161 ~]# cd /usr/local [root@host-10-1-1-161 local]# wget http://nginx.org/download/nginx-1.9.9.tar.gz [root@host-10-1-1-161 local]#tar xf nginx-1.9.9.tar.gz [root@host-10-1-1-161 local]# cd nginx-1.9.9 [root@ecs-01 nginx-1.9.9]# ./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx/nginx.conf --with-stream --with-http_stub_status_module --with-http_ssl_module #这个为主，不行的话再用下面 [root@ecs-01 nginx-1.9.9]# ./configure --prefix=/usr/local/nginx --conf-path=/usr/local/nginx/nginx.conf --with-stream --with-http_stub_status_module --with-http_ssl_module [root@ecs-01 nginx-1.9.9]# make [root@ecs-01 nginx-1.9.9]# make install
[root@ecs-01 nginx-1.9.9]# echo 'export PATH=$PATH:/usr/local/nginx/sbin' >> /etc/profile
[root@host-10-1-1-161 logs]# /usr/local/nginx/sbin/nginx -c /etc/nginx/nginx.conf
添加开机自启文件
[root@bogon ~]# cat /lib/systemd/system/nginx.service
#!/bin/bash
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target
设置nginx服务开机自启
[root@bogon ~]# systemctl enable nginx
启动nginx方式一、
nginx //启动
nginx -t //检查配置文件是否正常
nginx -s reload //重新载入配置文件
nginx -s stop //停止
nginx -s reopen //重启
启动nginx方式二、
启动nginx服务
systemctl start nginx.service
设置开机自启动
systemctl enable nginx.service
停止开机自启动
systemctl disable nginx.service
查看服务当前状态
systemctl status nginx.service
重新启动服务
systemctl restart nginx.service
查看所有已启动的服务
systemctl list-units --type=service
3、安装完成后加上下面两句话，否则报错
重要：修改配置文件使用虚拟机，否则怎么配置都不生效，添加如下用户
[root@host-10-1-1-161 html]# ll /etc/nginx/nginx.conf
-rw-r--r-- 1 root root 345 Aug 26 10:41 /etc/nginx/nginx.conf
[root@host-10-1-1-161 html]# vi /etc/nginx/nginx.conf
user root root; #说明：这里的user根据 自己的nginx.conf文件所在的目录的属主属性而定
worker_processes 1;
--with-stream ---支持TCP的意思
4、设置Nginx开机启动
编辑/etc下的rc.local文件
# vi /etc/rc.local
添加：
/usr/local/nginx/sbin/nginx
5、使用nginx
启动和停止 nginx
cd /usr/local/nginx/sbin
./nginx
./nginx -s stop
./nginx -s quit
./nginx -s reload
./nginx -s quit :此方法停止步骤是待 Nginx 进程处理任务完毕进行停止
./nginx -s stop :此方法相当于先查出 nginx 进程 id 再使用 kill 命令强制杀掉进程
查询 nginx 进程
ps aux | grep nginx
重启 nginx
先停止在启动（推荐），对 nginx 进行重启相当先停止再启动，即先执行停止命令再执行启动命令
./nginx -s quit
./nginx
重新加载配置文件，当 nginx 的配置 nginx.conf 修改后，想让配置生效需要重启 nginx，使用 -s reload 不用先停止 nginx 再 nginx 即可配置信息在 nginx 中生效，如下：
./nginx -s reload
报错解决：
1、centos安装nginx 报错：cp: `conf/koi-win' and `/usr/local/nginx/conf/koi-win' are the same file
解决：
删除/usr/local下的nginx,建一个空的nginx文件夹
将这一步改一下
./configure --prefix=/usr/local/nginx
TO
./configure --prefix=/usr/local/nginx --conf-path=/usr/local/nginx/nginx.conf
2、nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"
[root@host-10-1-1-161 ~]# nginx -s reload
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid"
[root@host-10-1-1-161 nginx]# cd /usr/local/nginx/logs/
[root@host-10-1-1-161 logs]# ls
access.log error.log nginx.pid
[root@host-10-1-1-161 logs]# rm -rf nginx.pid
3、nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
[root@host-10-1-1-161 ~]# nginx -s reload
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
[root@host-10-1-1-161 logs]# /usr/local/nginx/sbin/nginx -c /etc/nginx/nginx.conf
[root@host-10-1-1-161 logs]# /usr/local/nginx/sbin/nginx -s reload
[root@host-10-1-1-161 logs]# nginx -s reload
