Persediaan alam sekitar

1. Sediakan pelayan nginx ip192.168.1.133 port 81

Proses pemasangan: 

＃首先安装依赖：
yum -y install gcc-c++ 
yum -y install pcre pcre-devel 
yum -y install zlib zlib-devel 
yum -y install openssl openssl—devel
#注意 ： 安装nginx必须使用 root 用户安装
#创建一个nginx目录
mkdir /usr/local/src/nginx
#进入到nginx目录
cd /usr/local/src/nginx
#下载或上传安装包
wget http://nginx.org/download/nginx.tar.gz 或 rz上传
#解压安装包
tar -xvf nginx.tar.gz
#进入到解压后的目录
cd nginx
# 下面 才开始正式安装
#把nginx安装到指定用户的目录
mkdir -p /ucenter/soft/nginx
#安装配置 prefix为安装目录 user为用户 group为 组
./configure --prefix=/ucenter/soft/nginx --user=ucenter --group=ucenter
#编译
make 
#安装
make install
#在linux系统中由于非root用户不能占用80端口，所以需要使普通用户以root身份启动nginx。 
cd /ucenter/soft/nginx/sbin
#把soft文件下所有的文件所属者修改为ucener -r 表示递归
chown ucenter:ucenter ./soft/ -r
#修改 ./nginx 的所属为root
chown root nginx
#让普通用户可以使用80端口，可以使用root权限启用nginx
chmod u+s nginx
#修改配置文件 在修改配置文件之前 ，要备份该文件
cd conf/
# 要注意nginx 的工作进程，一般根据cpu的核数去修改
vim nginx.conf
#关闭防火墙，打开80端口
service iptables stop
#启动nginx
./nginx
#重启nginx
./nginx -s reload
#关闭nginx
./nginx -s stop

Sediakan pelayan tomcat, sediakan dahulu persekitaran java, tinggalkan langkah pemasangan jdk

Kemudian pasang 3 alamat IP pelayan tomcat: 192.168.1.143, port tomcat1 8080, port tomcat2 8081, tomcat83 Port 8083 .

Pada masa ini, mulakan tiga kucing jantan dan nginx masing-masing, akses dan muat semula setiap kali Halaman akan mengakses 8080 atau 8081 atau 8082 secara rawak, dan ID sesi yang muncul pada halaman juga berbeza Bagaimana kita harus membuat sesi perkongsian tiga kucing jantan ini.


Pada masa ini, pasang redis pada pelayan 192.168.1.143 yang mempunyai tiga tomcats Langkah-langkah pemasangan adalah seperti berikut: 

$ wget http://download.redis.io/releases/redis-3.2.3.tar.gz
$ tar xzf redis-3.2.3.tar.gz
$ cd redis-3.2.3
$ make malloc=libc
#启动redis src前面是安装的路径
$ src/redis-server &

#关闭redis
src/redis-cli shutdown
#使用redis 放入键值对 key value
$ src/redis-cli
127.0.0.1:6379> set foo bar
ok
127.0.0.1:6379> get foo
"bar"
$

Selepas memasang redis, pasang tiga tomcat libs. lima balang bergantung dalam folder masing-masing, iaitu

commons-pool2-2.0.jar

jedis-2.5.2.jar

tomcat-redis -session-manager1 .2.jar

tomcat-juli.jar

tomcat-juli-adapters.jar

Semua balang ada di sini,

Kemudian baiki konteksnya. xml fail tiga kucing jantan masing-masing dan tambahkan konfigurasi berikut 

<?xml version=&#39;1.0&#39; encoding=&#39;utf-8&#39;?>

<context>

 <!-- default set of monitored resources -->
 <watchedresource>web-inf/web.xml</watchedresource>

 
 <!-- 这里增加redis session共享的配置 6379是redis的端口-->
 <valve classname="com.orangefunction.tomcat.redissessions.redissessionhandlervalve" /> 
 <manager classname="com.orangefunction.tomcat.redissessions.redissessionmanager" 
 host="127.0.0.1" 
 port="6379" 
 database="0" 
 maxinactiveinterval="60" /> 
</context>

Pada masa ini, mulakan semula tiga kucing jantan dan nginx masing-masing Selepas menyemak log kucing jantan, kami mendapati tiada ralat luar biasa, yang bermakna kami berjaya. , kemudian mulakan ujian.

Kami mengakses alamat pelayan nginx:


Apa yang kami perolehi ialah tomcat1 port 8080, id sesi ialah 1a0625767f27ba95ef4d5f061fe0568d

Pada masa ini Tekan f5 untuk memuat semula halaman yang anda perolehi ialah tomcat2 port 8081. ID sesi masih 1a0625767f27ba95ef4d5f061fe0568dPada masa ini, ini bermakna kami telah berjaya membina tomcat + nginx load balancing + penyegerakan sesi redis! nginx membantu mengagihkan permintaan kami secara sama rata kepada tiga kucing jantan --> tomcat1, tomcat2 dan tomcat3 redis membantu kami menyegerakkan sesi, supaya prestasi pelayan kami akan bertambah baik Ramai, jika mana-mana tomcat gagal, ada tidak akan memberi kesan kepada keseluruhan perkhidmatan.
