第一步,安装mysql,
一、检查系统是否安装老版本,有的话干掉
#yum list installed | grep mysqlmysql-libs.x86_64 5.1.73-5.el6_6 @anaconda-CentOS-201508042137.x86_64/6.7 #yum -y remove mysql-libs.x86_64
二、安装及配置
# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm # rpm -ivh mysql-community-release-el6-5.noarch.rpm # yum repolist all | grep mysql
安装MYSQL数据库(网络原因,下载时间过长,这是唯一的缺点,如果机房网络环境好可以这样装)
# yum install mysql-community-server -y
设置为开机启动)
# chkconfig --list | grep mysqld # chkconfig mysqld on
三、设置远程root1.启动mysql和设置密码、登录
# service mysqld start # mysql_secure_installation
# mysql -uroot -p 2.建立远程root用户 mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘你设置的密码‘ WITH GRANT OPTION; mysql> flush privileges; 四、设置utf-8编码查看mysql原本编码: mysql> show variables like ‘character%‘; 设置编码 # vi /etc/my.cnf 如下(少补): [mysqld] character-set-server=utf8 collation-server=utf8_general_ci performance_schema_max_table_instances=400 table_definition_cache=400 table_open_cache=256 # 修改 sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION [mysql] default-character-set = utf8 [mysql.server] default-character-set = utf8 [mysqld_safe] default-character-set = utf8 [client] default-character-set = utf8 重启mysql # service mysqld restart 再次查看编码: # mysql -uroot -p mysql> show variables like ‘character%‘; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+8 rows in set (0.00 sec)
第二步,安装jdk,从网上下载jdk1.8,的rpm包,用sftp传到服务器上,rpm -ivh xxxx.rpm 即可。在安装前,检查旧版本,若有删掉。
安装后,自动配置好了,jdk和jre环境,可以用java -version,和 javac -version,查看版本。
第三步,安装tomcat,若有旧版本,先删除,
yum list installed | grep tomcat
yum -y remove xxx.xx
删除后,然后下在tomcat8.5,tar -xf xxxxx.tar.gz 到根目录下。
在/lib/systemd/system
目录下创建一个脚本文件tomcat.service,里面的内容如下
[Unit]
Description=Tomcat
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/tomcat/pid
ExecStart=/usr/local/tomcat/bin/catalina.sh start
ExecReload=/usr/local/tomcat/bin/catalina.sh restart
ExecStop=/usr/local/tomcat/bin/catalina.sh stop
[Install]
WantedBy=multi-user.target
在/usr/local/下面,建立tomcat的目录。确保路径真实有效。
在tomcat的bin/catalina.sh里面,添加
CATALINA_PID=/usr/local/tomcat/pid # OS specific support. $var _must_ be set to either true or false. cygwin=false ....略..
创建软链接
ln -s /lib/systemd/system/tomcat.service /etc/systemd/system/multi-user.target.wants/tomcat.service
创建好了,重载一下
systemctl daemon-reload
设置开机自启
systemctl enable tomcat
另外,需要改8080端口,在server.xml里修改。
