Nginx+Tomcat+Https 伺服器負載均衡配置

由於需要，得搭建個nginx+tomcat+https的伺服器，搜了搜網上的發現總是有錯，現在整理了些有用的，備忘。

環境：Centos6.5、JDK1.8、Tomcat8、Nginx1.10.1
準備材料：
1.JDK1.8安裝包jdk-8u102-linux-x64.tar.gz

2.Tomcat8安裝包apache-tomcat-8.0.37.tar.gz

3.Nginx1.10安裝包nginx-1.10.1.tar.gz

1、JDK安裝配置
解壓並安裝到/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環境變數

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

在底部加入以下內容

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

應用環境變數

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

檢測是否成功，顯示版本說明成功

[root@localhost ~]# java -version

2、Tomcat安裝配置
解壓並安裝到/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

預設tomcat是root身份運行的，這樣不安全，這裡設置普通用戶運行

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

運行tomcat

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

設置開機啟動

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

3、Nginx安裝配置
配置Nginx用戶

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

安裝依賴包

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

解壓併進入文件夾內

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

配置安裝

[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

這一步需要手動將ssl證書放入/usr/local/nginx/conf/目錄下，分別為cert.crt和cert.key文件
如果證書文件是其他格式，可以自行搜索轉換方法
如果無須配置https，更改443埠即可

        location = /50x.html {

        }
    }
}
