1、系统初始化

# 关闭防火墙

systemctl stop firewalld

systemctl disable firewalld

 

# 关闭selinux

sed -i 's/enforcing/disabled/' /etc/selinux/config #永久

setenforce 0 # 临时

 

# 关闭THP

echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo never > /sys/kernel/mm/transparent_hugepage/defrag

 

# 时间同步

yum install ntpdate -y

ntpdate time.windows.com

echo "*/5 * * * * /usr/sbin/ntpdate ntp.api.bz >/dev/null 2 >&1" >> /var/spool/cron/root

 

2、安装JAVA环境

tar -xzf jdk-11.0.9_linux-x64_bin.tar.gz -C /usr/local/

cd /usr/local/

mv jdk-11.0.9 java

 

启用环境变量:

cat << EOF >> /etc/profile

JAVA_HOME=/usr/local/java

JAVA_BIN=$JAVA_HOME/bin

PATH=$PATH:$JAVA_BIN

CLASSPATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export JAVA_HOME JAVA_BIN PATH CLASSPATH

EOF

然后source 使其生效

ln -vs /usr/local/java/bin/java /usr/bin/java

source /etc/profile

java -version

3、安装并配置MySQL

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar

rpm -qa | grep mariadb

rpm -e mariadb-libs-5.5.60-1.el7_5.x86_64 --nodeps

tar -xvf mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar

rpm -ivh mysql-community-common-8.0.28-1.el7.x86_64.rpm --nodeps --force

rpm -ivh mysql-community-libs-8.0.28-1.el7.x86_64.rpm --nodeps --force

use mysql;

update user set host='%' where user ='root';

alter user 'root'@'%' identified with mysql_native_password by '123456';

flush privileges;

4、安装并配置Maven

wget https://dlcdn.Apache.org/maven/maven-3/3.8.4/binaries/apache-maven-3.8.4-bin.tar.gz --no-check-certificate

tar -xzf apache-maven-3.8.4-bin.tar.gz -C /usr/local/

cd /usr/local/

mv apache-maven-3.8.4 maven

vim /etc/profile

export MAVNE_HOME=/usr/local/maven

export PATH=$PATH:$JAVA_HOME/bin:$MAVNE_HOME/bin

source /etc/profile

# 检查maven安装

mvn -version

5、配置apollo数据库

wget https://raw.githubusercontent.com/ctripcorp/apollo/master/scripts/sql/apolloconfigdb.sql

wget https://raw.githubusercontent.com/ctripcorp/apollo/master/scripts/sql/apolloportaldb.sql

mysql -uroot -p123456

source /root/apolloconfigdb.sql;

source /root/apolloportaldb.sql;

6、配置并启动apollo

wget https://github.com/ctripcorp/apollo/releases/download/v1.9.1/apollo-adminservice-1.9.1-github.zip

wget https://github.com/ctripcorp/apollo/releases/download/v1.9.1/apollo-configservice-1.9.1-github.zip

wget https://github.com/ctripcorp/apollo/releases/download/v1.9.1/apollo-portal-1.9.1-github.zip

 

unzip apollo-adminservice-1.9.1-github.zip -d /data/apollo/apollo-adminservice

unzip apollo-configservice-1.9.1-github.zip -d /data/apollo/apollo-configservice

unzip apollo-portal-1.9.1-github.zip -d /data/apollo/apollo-portal

 

修改配置

vi /data/apollo/apollo-adminservice/config/Application-github.properties

# DataSource

spring.datasource.url = jdbc:mysql://192.168.52.20:3306/ApolloConfigDB?characterEncoding=utf8

spring.datasource.username = root

spring.datasource.password = 123456

 

vi /data/apollo/apollo-configservice/config/application-github.properties

# DataSource

spring.datasource.url = jdbc:mysql://192.168.52.20:3306/ApolloConfigDB?characterEncoding=utf8

spring.datasource.username = root

spring.datasource.password = 123456

 

vi /data/apollo/apollo-portal/config/application-github.properties

# DataSource

spring.datasource.url = jdbc:mysql://192.168.52.20:3306/ApolloPortalDB?characterEncoding=utf8

spring.datasource.username = root

spring.datasource.password = 123456

 

修改端口启动和日志路径

vi /data/apollo/apollo-adminservice/scripts/startup.sh

LOG_DIR=/data/logs/apollo-adminservice

export JAVA_OPTS="-Xms2048m -Xmx2048m -Xss256k -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m -XX:NewSize=256m -XX:MaxNewSize=1024m -XX:SurvivorRatio=8"

 

vi /data/apollo/apollo-configservice/scripts/startup.sh

LOG_DIR=/data/logs/apollo-configservice

export JAVA_OPTS="-Xms2048m -Xmx2048m -Xss256k -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m -XX:NewSize=256m -XX:MaxNewSize=1024m -XX:SurvivorRatio=8"

 

vi /data/apollo/apollo-portal/scripts/startup.sh

LOG_DIR=/data/logs/apollo-portal

export JAVA_OPTS="-Xms2048m -Xmx2048m -Xss256k -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m -XX:NewSize=256m -XX:MaxNewSize=1024m -XX:SurvivorRatio=8"

修改protal组件的apollo-env.properties

vi /data/apollo/apollo-portal/config/apollo-env.properties

local.meta=http://localhost:8080

dev.meta=http://localhost:8080

fat.meta=http://fill-in-fat-meta-server:8080

uat.meta=http://fill-in-uat-meta-server:8080

lpt.meta=${lpt_meta}

pro.meta=http://fill-in-pro-meta-server:8080

#启动脚本

cat apollo-start.sh

/data/apollo/apollo-configservice/scripts/startup.sh

/data/apollo/apollo-adminservice/scripts/startup.sh

/data/apollo/apollo-portal/scripts/startup.sh

 

#停止脚本

7、配置 apollo测试样例

1、maven 生成 jar 包

vi /usr/local/maven/conf/settings.xml

### 修改为国内源 ###

<mirror>

<id>alimaven</id>

<name>aliyun maven</name>

<url>https://maven.aliyun.com/repository/public/</url>

<mirrorOf>*</mirrorOf>

</mirror>

tar xf springboot-apollo-demo.tar.gz -C /data/

cd /data/springboot-apollo-demo/

cat src/main/resources/application.yaml

server:

port: 7070

spring:

application:

name: apollo-demo

app:

id: apollo-demo # 应用ID 对应 apollo 项目中的AppId

apollo:

cacheDir: /opt/data/ # 配置本地配置缓存目录

meta: http://localhost:8080 # 配置中心地址


autoUpdateInjectedSpringProperties: true # 是否开启 Spring 参数自动更新

bootstrap:

enabled: true # 是否开启 Apollo

eagerLoad:

enabled: false # 将Apollo加载提到初始化日志系统之前

mvn clean package

cd target/

java -jar apollo-demo-0.0.1.jar
