*通过以下命令手动生成证书:
<taddm_dist_dir>/external/<jdk-for-platform>/bin/keytool -delete -alias collation -keystore <taddm_dist_dir>/etc/serverkeys -storepass <ssl-password>
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -genkey -alias collation -keystore <taddm_dist_dir>/etc/serverkeys -validity 3650 -keyAlg RSA -sigalg SHA256WithRSA -keypass <ssl-password> -storepass <ssl-password> -dname "CN=<TADDM_SERVER_FQDN>, OU=Engineering, O=IBM, L=Palo Alto, S=California, C=US"
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -export -alias collation -noprompt -keystore <taddm_dist_dir>/etc/serverkeys -keypass <ssl-password> -storepass <ssl-password> -file <taddm_dist_dir>/cert.tmp
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -delete -alias collation -noprompt -keystore <taddm_dist_dir>/etc/jssecacerts.cert -storepass <ssl-password>
<taddm_dist_dir>external/<jdk-for-platform>/bin/keytool -import -alias collation -noprompt -keystore <taddm_dist_dir>/etc/jssecacerts.cert -keypass <ssl-password> -storepass <ssl-password> -file <taddm_dist_dir>/cert.tmp
