[操作系统]Nginx+Tomcat+Https 服务器负载均衡配置


由于需要,得搭建个nginx+tomcat+https的服务器,搜了搜网上的发现总是有错,现在整理了些有用的,备忘。

环境:Centos6.5、JDK1.8、Tomcat8、Nginx1.10.1
准备材料:
1.JDK1.8安装包jdk-8u102-linux-x64.tar.gz

2.Tomcat8安装包apache-tomcat-8.0.37.tar.gz

3.Nginx1.10安装包nginx-1.10.1.tar.gz

 

1、JDK安装配置
解压并安装到/usr/local/jdk

[root@localhost ~]# tar zxvf jdk-8u102-linux-x64.tar.gz[root@localhost ~]# mv jdk1.8.0_102 /usr/local/jdk

配置JDK环境变量

[root@localhost ~]# vi /etc/profile

在底部加入以下内容

JAVA_HOME=/usr/local/jdkJRE_HOME=$JAVA_HOME/jreCLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATHPATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATHexport JAVA_HOME JRE_HOME PATH CLASSPATH

应用环境变量

[root@localhost ~]# source /etc/profile

检测是否成功,显示版本说明成功

[root@localhost ~]# java -version

2、Tomcat安装配置
解压并安装到/usr/local/tomcat

[root@localhost ~]# tar zxvf apache-tomcat-8.0.37.tar.gz[root@localhost ~]# mv apache-tomcat-8.0.37 /usr/local/tomcat

默认tomcat是root身份运行的,这样不安全,这里设置普通用户运行

[root@localhost ~]# groupadd tomcat[root@localhost ~]# useradd -g tomcat tomcat[root@localhost ~]# passwd tomcat[root@localhost ~]# chown tomcat.tomcat -R /usr/local/tomcat

运行tomcat

[root@localhost ~]# su - tomcat /usr/local/tomcat/bin/startup.sh

设置开机启动

[root@localhost ~]# echo "su - tomcat /usr/local/tomcat/bin/startup.sh" >> /etc/rc.local

3、Nginx安装配置
配置Nginx用户

[root@localhost ~]# groupadd nginx[root@localhost ~]# useradd -g nginx -s /sbin/nologin nginx

安装依赖包

[root@localhost ~]# yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc gcc-c++

解压并进入文件夹内

[root@localhost ~]# tar zxvf nginx-1.10.1.tar.gz[root@localhost ~]# cd nginx-1.10.1

配置安装

[root@localhost nginx-1.10.1]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module[root@localhost nginx-1.10.1]# make && make install

配置Nginx

[root@localhost ~]# vi /usr/local/nginx/conf/nginx.conf

这一步需要手动将ssl证书放入/usr/local/nginx/conf/目录下,分别为cert.crt和cert.key文件
如果证书文件是其他格式,可以自行搜索转换方法
如果无须配置https,更改443端口即可

启动服务器

/usr/local/nginx/sbin/nginx

浏览器访问出现小猫即成功。
