Nginx+Tomcat+Https 服务器负载均衡配置实践方案详解

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/jdk JRE_HOME=$JAVA_HOME/jre CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH export 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

location = /50x.html {

}
}
}
启动服务器
/usr/local/nginx/sbin/nginx
浏览器访问出现小猫即成功。
