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
