========================配置
vim /opt/nginx/conf/nginx.conf

修改前面几行为：

user www-data www-data;

worker_processes 1;

error_log logs/error.log crit;

pid logs/nginx.pid;

events{

use epoll;

worker_connections 65535;

}

chmod 400 /root/.ssh/id* 
chown -R www-data:www-data /yigao

4.7 测试和运行

[root@centos ~]# cd /opt/nginx

[root@centos ~]# ldconfig

[root@centos ~]# ./sbin/nginx -t

如果显示下面信息，即表示配置没问题

nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /opt/nginx/conf/nginx.conf test is successful

 

输入代码运行nginx服务

[root@centos ~]# ./sbin/nginx　

输入代码检测是否支持加速

查看是否生效

[root@centos ~]# lsof -n | grep jemalloc

#停止firewall 

[root@centos ~]# systemctl stop firewalld.service 

#禁止firewall开机启动

[root@centos ~]# systemctl disable firewalld.service

安装 iptables

[root@centos ~]# yum install iptables-services 

设置防火墙规则 (增加80端口)

[root@centos ~]# vim /etc/sysconfig/iptables

打开文件，增加80端口那一行

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

 

:wq #保存退出

 

#重启防火墙使配置生效

[root@centos ~]# systemctl restart iptables.service

#设置防火墙开机启动

[root@centos ~]# systemctl enable iptables.service  

 4.9 作为服务，开机后启动

[root@centos ~]# vim /usr/lib/systemd/system/tengine.service

增加以下内容

[Unit]
Description=The nginx HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/opt/nginx/logs/nginx.pid

:wq 保存退出

 

 [root@centos ~]# systemctl stop tengine

 [root@centos ~]# systemctl start tengine

 [root@centos ~]# systemctl reload tengine

 [root@centos ~]# systemctl enable tengine

 [root@centos ~]# shutdown -r now
