jdk1.8.0 安装配置

#wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install -y java-1.8.0-openjdk*
java -version # java -verbose 查看jdk安装位置

tomcat-8.5.42 安装配置 负载均衡

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.5.42/bin/apache-tomcat-8.5.42.tar.gz
tar zxf apache-tomcat-8.5.42.tar.gz
mv apache-tomcat-8.5.42 /usr/local/tomcat-8080
cp -r tomcat-8080 tomcat-8081

vi /etc/profile
(
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64
export JAVA_HOME

export CLASSPATH PATH
)
source /etc/profile
/usr/local/tomcat-8080/bin/version.sh #查看tomcat版本
vi /usr/local/tomcat-8081/conf/server.xml #改三个端口避免冲突
vi catalina.sh
（
#OS specific support. var must be set to either true or false.
在上面代码的下面增加如下代码
第二个tomcat:
export CATALINA_BASE=$CATALINE_BASE1
export CATALINA_HOME=$TOMCAT_HOME1
）

firewall-cmd --permanent --add-port=8080/tcp #firewall-cmd --permanent --remove-port=8080/tcp
firewall-cmd --permanent --add-port=8081/tcp
firewall-cmd --reload

netstat -anpt | grep java #查看端口监听信息

vi /usr/local/tomcat-8080/conf/server.xml #找到对应位置 添加jvmRoute 和Context


vi /usr/local/tomcat-8081/conf/server.xml

redis-5.0.5 安装配置 实现会话保持

wget http://download.redis.io/releases/redis-5.0.5.tar.gz
tar zxf redis-5.0.5
cd redis-5.0.5
make && make install #默认安装到/usr/local,/usr/local/bin,/usr/local/share,/usr/local/include,/usr/local/lib,/usr/local/share/man目录下

./install_server.sh #初始化 中间提示Please select the redis executable path [] 输入 /usr/local/bin/redis-server
#配置文件为/etc/redis/6379.conf ，日志文件为/var/log/redis_6379.log
#数据文件dump.rdb存放到/var/lib/redis/6379目录 ，启动脚本为/etc/init.d/redis_6379

#启动redis

配置tomcat session redis同步

#将redisson-all-3.11.0.jar和redisson-tomcat-8-3.11.0.jar上传到tomcat的lib目录下
vi /usr/local/tomcat-8080/conf/context.xml vi /usr/local/tomcat-8081/conf/context.xml
configPath="${catalina.base}/redisson.conf" readMode=“REDIS” updateMode=“DEFAULT”/>
vi /usr/local/tomcat-8080/redisson.conf (context.xml里配置的catalina.base 是tomcat的根目录)
{
“singleServerConfig”:{
“idleConnectionTimeout”:10000,
“pingTimeout”:1000,
“connectTimeout”:10000,
“timeout”:3000,
“retryAttempts”:3,
“retryInterval”:1500,
“password”:“redis@123”,
“subscriptionsPerConnection”:5,
“clientName”:null,
“address”: “redis://127.0.0.1:6379”,
“subscriptionConnectionMinimumIdleSize”:1,
“subscriptionConnectionPoolSize”:50,
“connectionMinimumIdleSize”:32,
“connectionPoolSize”:64,
“database”:0,
“dnsMonitoringInterval”:5000
},
“threads”:0,
“nettyThreads”:0,
“codec”:{
“class”:“org.redisson.codec.JsonJacksonCodec”
},
“transportMode”:“NIO”
}
#重启tomcat访问测试效果 http://192.168.0.205:8089/index.jsp
###如果遇到后来又装了一个redis导致覆盖无法正常启动的问题时，删除对应的pid文件和dump文件，重启即可
#执行systemctl status redis_6379.service 报错信息如下/var/run/redis_6379.pid exists, process is already running or crashed
#rm -rf /var/run/redis_6379.pid
#rm -rf /var/lib/redis/6379/dump.rdb
#systemctl restart redis_6379.service

mysql5.7.26 安装配置

tar -xvzf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
