I bought an Alibaba Cloud server in the past two days to play
First install jdk, tomcat, this is relatively simple
Then modify the configuration file profile in etc.
add on the last line
JAVA_HOME=/usr/local/java/jdk1.7.0_76 PATH=$JAVA_HOME/bin:/sbin:/usr/bin:/usr/sbin:$PATH CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export JAVA_HOME export PATH export CLASSPATH export TOMCAT_HOME=/usr/local/java/tomcat
Then execute source /etc/profile and it will be ok
Execute java -version to view the jdk version
The following mainly talks about the installation of mysql
This really took a lot of effort. I started to download mysql.tar.gz and installed it. As a result, various errors occurred. Baidu has been modifying various files. In the end, I still reported some pid errors, so I gave up decisively after a day.
Now download the rpm file from the mysql official website
Uninstall mariadb-lib before installing
[root@5201351 ~]# rpm -qa|grep mariadb mariadb-libs-5.5.41-2.el7_0.x86_64 [root@5201351 ~]# rpm -e mariadb-libs-5.5.41-2.el7_0.x86_64 --nodeps
Go to mysql's official website to download the latest version of mysql's rpm collection package
It's a 550M package
Then tar -xf the bundle.tar package
After getting the following rpm packages, we mainly use four community-libs, community-common, community-client, community-server
We install it one by one, using rpm -ivh to install
When installing, you may encounter
libaio.so.1: cannot open shared object file: No such file or directory 这样的问题
可以yum install libaio* 来解决 ,如果还是不行,直接在安装命令的后面加--nodeps --force 解决依赖 强制装
可以解决
四个安装好了之后 执行
# mysqld --initialize
会在/var/log/mysqld.log生成随机密码
找到自动生成的密码
更改mysql数据库目录的所属用户及其所属组,然后启动mysql数据库
[root@5201351 ~]# chown mysql:mysql /var/lib/mysql -R [root@5201351 ~]# systemctl start mysqld.service
根据之前的密码登录到mysql,更改root用户的密码,新版的mysql在第一次登录后更改密码前是不能执行任何命令的
[root@5201351 ~]# mysql -uroot -p'ij+xyCYm:9&X' mysql> set password=password('root');
此时mysql 已经安装好了,并且有了一个用户名为root,密码也为root的用户
若要在自己的客户端远程登录 则还要赋权限,因为它默认只能本机登录
根据上面的步骤,或者自己直接百度就ok
