私はlibがtomcat7するためのmysql-connetorsをコピーします。

sudoのLN -s /var/lib/tomcat7/webapps/ScadaBR/WEB-INF/lib/mysql-connector-java-3.1.8 -bin.jar /usr/share/tomcat7/lib/mysql-connector-java-3.1.8-bin.jar

sudo ln -s/var/lib/tomcat7/webapps/ScadaBR/WEB-INF/lib /mysql-connector-java-5.1.38-bin.jar /usr/share/tomcat7/lib/mysql-connector-java-5.1.38-bin.jar

sudo ln -s/var/lib/tomcat7 /webapps/ScadaBR/WEB-INF/lib/mysql-connector-java-5.1。 7-bin.jar /usr/share/tomcat7/lib/mysql-connector-java-5.1.7-bin.jar

私はそれが問題ではないと思うが、私は何があるかわからない。 ？

Answer 1

大丈夫です。

ScadaLTSは、いくつかの方法でデータベースに接続するように設定できます。直接

db.type=mysql 
db.url=jdbc:mysql://localhost:3306/scadalts 
db.username=xxxxx 
db.password=xxxxx 
db.pool.maxActive=10 
db.pool.maxIdle=10 

は*ライブラリTomcatにmysqlの-connetorを取り付ける必要がありませんScadaLTS/WebContentを/ WEB-INF/env.propertiesでデータベース

設定に接続する

1。 Tomcatの/ Tomcatの/ CONFの

2 JNDIを使用したデータベースへの接続（デフォルト）

設定ScadaLTS/WebContentを/ WEB-INF/env.propertiesで

db.type=mysql 
db.datasource=true 
db.datasourceName=java:comp/env/jdbc/scadalts 
#db.url=jdbc:mysql://localhost:3306/scadalts (commented for comparison) 
#db.username=xxxxx       (commented for comparison) 
#db.password=xxxxx       (commented for comparison) 
#db.pool.maxActive=10      (commented for comparison)

は、コピーのmysql-connector-あなたがよくあるのtomcat/libににmysqlのコネクタをコピーしたよりも、結論として

More about JNDI Datasource HOW-TO

のtomcat/libsのディレクトリに*が必要です。

Configured system available in docker scadalts-dev

それでも接続の問題を持っているなら、あなたはチェックしている：あなたはMySQLデータベースが設定

1. 持っていますか？ （スキャンダルなど）
2. 正しく設定されたユーザーとパスワードがありますか？
3. 設定ファイルに正しいデータがありますか？

設定ScadaLTS/WebContent/WEB-INF/env。私はScadaLTS/WebContentを/ WEB-INF /にScadaBR/WEB-INF /クラスからenv.propertiesをコピーしようとTomcatの/tomcat/conf/context.xml
