Linux(CentOS 7)下安装配置nginx代理商多个tomcat实例和应使用

注：本文 nginx版本：1.12.2 Tomcat版本: 9.0.2

*yum安装

[root@izbp1di2a9vvogy93gw0onz local]# rpm -ivh https://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

[root@izbp1di2a9vvogy93gw0onz local]# yum install nginx

*启动

[root@izbp1di2a9vvogy93gw0onz local]# systemctl start nginx.service

启动报错：

Job for nginx.service failed because the control process exited with error code. See “systemctl status nginx.service” and “journalctl -xe” for details.

● nginx.service – nginx – high performance web server

Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)

能看到是bind to 0.0.0.0:80 fail——绑定80端口失败，

查看nginx错误日志（可可以要先改log文件权限）

[root@izbp1di2a9vvogy93gw0onz local]# /var/log/nginx/error.log

/var/log/nginx/error.log: line 1: syntax error near unexpected token ('

/var/log/nginx/error.log: line 1:2017/12/19 10:54:17 [emerg] 26705#26705: >>bind() to 0.0.0.0:80 failed (98: Address already in use)’

80端口早已被用，将占使用80端口的Tomcat关闭后启动成功

[root@izbp1di2a9vvogy93gw0onz local]# systemctl start nginx.service

可使用[root@izbp1di2a9vvogy93gw0onz local]# rpm -ql nginx | grep nginx
