1、准备软件包 在运维主机`HDSS7-200.host.com`上： 安装下载：https://github.com/ctripcorp/apollo/releases/download/v1.3.0/apollo-adminservice-1.3.0-github.zip ``` mkdir /data/dockerfile/apollo-adminservice && unzip -o apollo-adminservice-1.3.0-github.zip -d /data/dockerfile/apollo-adminservice ``` 2、制作Docker镜像 在运维主机`HDSS7-200.host.com`上： 配置数据库连接串 ``` /data/dockerfile/apollo-adminservice cat config/application-github.properties spring.datasource.url = jdbc:mysql://mysql.od.com:3306/ApolloConfigDB?characterEncoding=utf8 spring.datasource.username = apolloconfig spring.datasource.password = 123456 ``` 更新starup.sh /data/dockerfile/apollo-adminservice/scripts/startup.sh ``` #!/bin/bash SERVICE_NAME=apollo-adminservice ## Adjust log dir if necessary LOG_DIR=/opt/logs/apollo-adminservice ## Adjust server port if necessary SERVER_PORT=8080 APOLLO_ADMIN_SERVICE_NAME=$(hostname -i) # SERVER_URL="http://localhost:${SERVER_PORT}" SERVER_URL="http://${APOLLO_ADMIN_SERVICE_NAME}:${SERVER_PORT}" ## Adjust memory settings if necessary #export JAVA_OPTS="-Xms2560m -Xmx2560m -Xss256k -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=384m -XX:NewSize=1536m -XX:MaxNewSize=1536m -XX:SurvivorRatio=8" ## Only uncomment the following when you are using server jvm #export JAVA_OPTS="$JAVA_OPTS -server -XX:-ReduceInitialCardMarks" ########### The following is the same for configservice, adminservice, portal ########### export JAVA_OPTS="$JAVA_OPTS -XX:ParallelGCThreads=4 -XX:MaxTenuringThreshold=9 -XX:+DisableExplicitGC -XX:+ScavengeBeforeFullGC -XX:SoftRefLRUPolicyMSPerMB=0 -XX:+ExplicitGCInvokesConcurrent -XX:+PrintGCDetails -XX:+HeapDumpOnOutOfMemoryError -XX:-OmitStackTraceInFastThrow -Duser.timezone=Asia/Shanghai -Dclient.encoding.override=UTF-8 -Dfile.encoding=UTF-8 -Djava.security.egd=file:/dev/./urandom" export JAVA_OPTS="$JAVA_OPTS -Dserver.port=$SERVER_PORT -Dlogging.file=$LOG_DIR/$SERVICE_NAME.log -XX:HeapDumpPath=$LOG_DIR/HeapDumpOnOutOfMemoryError/" # Find Java if [[ -n "$JAVA_HOME" ]] && [[ -x "$JAVA_HOME/bin/java" ]]; then javaexe="$JAVA_HOME/bin/java" elif type -p java > /dev/null 2>&1; then javaexe=$(type -p java) elif [[ -x "/usr/bin/java" ]]; then javaexe="/usr/bin/java" else echo "Unable to find Java" exit 1 fi if [[ "$javaexe" ]]; then version=$("$javaexe" -version 2>&1 | awk -F '"' '/version/ {print $2}') version=$(echo "$version" | awk -F.
