tomcat安装以及配置
# 一、tomcat安装
#使用mkdir指令生成新的路径，用于解压tomcat压缩包
cd /usr/local
mkdir tomcat
#跳转到tomcat解压路径
cd /usr/local/tomcat
#下载tomcat压缩包（下载链接自己去apache官网复制即可）
wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.93/bin/apache-tomcat-7.0.93.tar.gz
#解压tomcat压缩包
tar -zxvf apache-tomcat-7.0.93.tar.gz
#查看是否已经解压成功
ls
#新建tomcat1和tomcat2文件目录，分别用于不同的项目发布
mkdir tomcat1
mkdir tomcat2
#将解压的apache-tomcat-7.0.93分别复制到tomcat1以及tomcat2路径下
cp apache-tomcat-7.0.93 tomcat1 -rf
cp apache-tomcat-7.0.93 tomcat2 -rf
#二、tomcat文件配置以及环境变量的配置
#配置环境变量，分别将tomcat1、tomcat2文件路径都添加到/etc/profile文件下
vi /etc/profile
#tomcat1
export CATALINA_HOME1=/usr/local/services/tomcat/tomcat1/apache-tomcat-7.0.93
export CATALINA_BASE1=/usr/local/services/tomcat/tomcat1/apache-tomcat-7.0.93
export TOMCAT_HOME1=/usr/local/services/tomcat/tomcat1/apache-tomcat-7.0.93
#tomcat2
export CATALINA_HOME2=/usr/local/services/tomcat/tomcat2/apache-tomcat-7.0.93
export CATALINA_BASE2=/usr/local/services/tomcat/tomcat2/apache-tomcat-7.0.93
export TOMCAT_HOME2=/usr/local/services/tomcat/tomcat2/apache-tomcat-7.0.93
#退出并保存配置文件，并且执行配置文件的更新
source /etc/profile
#修改tomcat2的相关配置文件（tomcat1的配置文件保持默认状态即可）
cd /usr/local/services/tomcat/tomcat2/apache-tomcat-7.0.93/conf
vi server.xml
#tomcat2仲的server.xml文件修改内容如下：，共三处
#8005修改为8006
<Server port="8005" shutdown="SHUTDOWN">
#8080端口号修改为8081
<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
#8009端口修改为8010
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
#修改好conf路径下的server.xml文件后，修改bin文件目录下的catalina.sh
vi catalina.sh
#在catalina.sh 文件下添加一下内容
#先在catalina.sh文件下，找到
# OS specific support. $var _must_ be set to either true or false
#并且添加以下的内容
export CATALINA_BASE=$CATALINA_BASE2
export CATALINA_HOME=$CATALINA_HOME2
#分别执行tomcat1和tomcat2的启动脚本，浏览器访问对应端口，启动tomcat1、tomcat2成功
/usr/local/services/tomcat/tomcat1/apache-tomcat-7.0.93/bin/startup.sh
/usr/local/services/tomcat/tomcat2/apache-tomcat-7.0.93/bin/startup.sh
#显示以下提示信息表示已经启动成功

Tomcat started
#配置两台tomcat完成！！最后添加对应的war包到对应的tocmat中的webapp文件夹下重新启动即可！！nginx安装：
#三、nginx安装
#安装相关依赖
yum -y install gcc
yum -y install pcre-devel
yum -y install zlib zlib-devel
yum -y install openssl openssl-devel
#nginx压缩包下载
cd /usr/local/services/nginx
wget http://nginx.org/download/nginx-1.12.2.tar.gz
#解压安装包
tar -zxvf nginx-1.12.2.tar.gz
#执行脚本文件
cd /usr/local/services/nginx/nginx-1.12.2
./configure
#编译
make
make install
# 查看nginx安装到哪里
whereis nginx
#默认安装路径如下；
/usr/local/nginx/sbin/nginx
#四、nginx配置
#配置开机启动 打开配置文件
vi /etc/rc.d/rc.local
# 添加 nginx 启动指令
/usr/local/nginx/sbin/nginx
# 赋予执行权限
chmod 755 /etc/rc.d/rc.local#添加nginx快速启动脚本
vi /usr/bin/nginx
#添加脚本内容如下：
