一次机器初始化安装软件的经过

来了一台华为的服务器，需要安装java以及mysql。

好吧，开干

• 安装java

cd /usr/localwget http://soft.ops.ac.cn/java/jdk-7u79-linux-x64.tar.gztar xzvf jdk-7u79-linux-x64.tar.gzln -s jdk-7u79-linux-x64 javaecho 'export PATH=/usr/local/java/bin' >> /etc/profileecho 'export JAVA_HOME=/usr/local/java' >> /etc/profile

• 安装mysql

yum install mysql mysql-server mysql-devel --enablerepo=mysql-community

总结：
1. 排障的时候，如果是shell程序，可以用 set -x在开头，这样就可以debug shell程序了。
2. selinux没有特别要求就关闭吧，否则mysql这种，调整路径后，也没法启动
3. 虽然只是安装java和mysql，但是还是花了3个小时左右，有点太浪费了。
