# 1.安装 #

## 1.1安装gcc gcc-c++(如新环境,未安装请先安装) ##

$ yum install -y gcc gcc-c++

## 1.2安装PCRE库 ##

$ cd /usr/local/
    $ wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.33/pcre-8.33.tar.gz
    $ tar -zxvf pcre-8.36.tar.gz
    $ cd pcre-8.36
    $ ./configure
    $ make && make install
     
    如报错:configure: error: You need a C++ compiler for C++ support
    解决:yum install -y gcc gcc-c++

## 1.3安装SSL库 ##

$ cd /usr/local/
    $ wget http://www.openssl.org/source/openssl-1.0.1j.tar.gz
    $ tar -zxvf openssl-1.0.1j.tar.gz
    $ cd openssl-1.0.1j
    $ ./config
    $ make && make install

## 1.4安装zlib库存 ##

$ cd /usr/local/
    $ wget http://zlib.net/zlib-1.2.11.tar.gz
    $ tar -zxvf zlib-1.2.11.tar.gz
    $ cd  zlib-1.2.11
    $ ./configure
    $ make && make install

## 1.5安装nginx ##

$ cd /usr/local/
    $ wget http://nginx.org/download/nginx-1.8.0.tar.gz
    $ tar -zxvf nginx-1.8.0.tar.gz
    $ cd nginx-1.8.0 
    $ ./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_gzip_static_module --with-http_realip_module --with-http_sub_module --with-http_ssl_module
    
    make && make install

## 1.6启动 ##

$ /usr/local/nginx/sbin/nginx

启动：nginx

停止：nginx -s stop

重新加载： nginx -s reload

打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。

其他部分命令:

$ pkill nginx                                    # 强制关闭
    /usr/local/nginx/sbin/nginx -s reload            # 重新载入配置文件
    /usr/local/nginx/sbin/nginx -s reopen            # 重启 Nginx
    /usr/local/nginx/sbin/nginx -s stop              # 停止 Nginx

# 2.配置tomcat #

在服务器上配置tomcatA和tomcatB。

将两个tomcat的端口改成不一样的，确保没有被占用，然后[添加开放端口][Link 1]和配置服务器安全组。

修改tomcatA配置

conf/server.xml

<?xml version="1.0" encoding="UTF-8"?>
    
    <Server port="8005" shutdown="SHUTDOWN">
      <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
      
      
      <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
      
      <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
      <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
      <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
    
      <GlobalNamingResources>
    
        <Resource name="UserDatabase" auth="Container"
                  type="org.apache.catalina.UserDatabase"
                  description="User database that can be updated and saved"
                  factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
                  pathname="conf/tomcat-users.xml" />
      </GlobalNamingResources>
    
      <Service name="Catalina">
    
        <Connector port="8080" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="8443" />
    
        <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    
        <Engine name="Catalina" defaultHost="localhost">
    
          <Realm className="org.apache.catalina.realm.LockOutRealm">
    
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                   resourceName="UserDatabase"/>
          </Realm>
    
          <Host name="localhost"  appBase="webapps"
                unpackWARs="true" autoDeploy="true">
    
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                   prefix="localhost_access_log" suffix=".txt"
                   pattern="%h %l %u %t "%r" %s %b" />
    
          </Host>
        </Engine>
      </Service>
    </Server>

修改tomcatB配置

conf/server.xml

<?xml version="1.0" encoding="UTF-8"?>
    
    <Server port="8006" shutdown="SHUTDOWN">
      <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
      
      
      <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
      
      <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
      <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
      <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
    
    
      <GlobalNamingResources>
    
        <Resource name="UserDatabase" auth="Container"
                  type="org.apache.catalina.UserDatabase"
                  description="User database that can be updated and saved"
                  factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
                  pathname="conf/tomcat-users.xml" />
      </GlobalNamingResources>
    
      <Service name="Catalina">
    
        <Connector port="8090" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="8444" />
     
        <Connector port="8010" protocol="AJP/1.3" redirectPort="8444" />
    
        <Engine name="Catalina" defaultHost="localhost">
    
          <Realm className="org.apache.catalina.realm.LockOutRealm">
    
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                   resourceName="UserDatabase"/>
          </Realm>
    
          <Host name="localhost"  appBase="webapps"
                unpackWARs="true" autoDeploy="true">
    
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                   prefix="localhost_access_log" suffix=".txt"
                   pattern="%h %l %u %t "%r" %s %b" />
    
          </Host>
        </Engine>
      </Service>
    </Server>

启动tomcatA和tomcatB

[启动报错][Link 2]

# 3.使用Nginx和tomcat做负载均衡 #

## 3.1修改Nginx文件 ##

conf/nginx.conf

upstream test {
    		server 127.0.0.1:8080;
    		server 127.0.0.1:8090;
    	}
    
        server {
            listen       80;
            server_name  localhost;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            location / {
                root   html;
                index  index.html index.htm;
    			proxy_pass http://test;  
            }
    
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
    
        }

## 3.2 启动 ##

启动tomcatA和tongcatB，加载配置文件，启动Nginx

## 3.3测试 ##
