arm服务器centos下安装mysql_Centos服务器搭建（4）——安装mysql
1.先检查系统有没有安装mysql
[root@iZ2873rjubzZ opt]# rpm -qa|grep mysql
# 我们看到，并没有安装mysql，但是有一个mysql的libs开发包插件，他是干什么的呢？
# 解释：由于CentOS6.4系统自带就有postfix服务，而这个mysql-libs呢就是支持这个postfix服务的，如果我们不使用到postfix，那就卸载掉吧，而且每一个mysql-server安装的时候，后自带安装上这个mysql-libs。
#删除mysl-;ib，系统就干净了
[root@iZ2873rjubzZ opt]# yum remove mysql-libs
2 下载mysql-5.6.21.tar.gz, 我们准备安装在/user/local 数据放在/uer/local/data 下
[root@iZ2873rjubzZ ~]# groupadd mysql #创建用户组mysql
[root@iZ2873rjubzZ~]# useradd -g mysql mysql -s /bin/false #创建用户mysql 不能远程登录[root@iZ2873rjubzZ~]# mkdir /usr/local/mysql
[root@iZ2873rjubzZ~]# mkdir /usr/local/mysql/data
[root@iZ2873rjubzZ~]# cp mysql-5.6.21.tar.gz /usr/local
[root@iZ285pj7jhrZ ~]# cd /usr/local/
[root@iZ285pj7jhrZ local]# tar -xzvf mysql-5.6.21.tar.gz #解压
#安装cmake编译环境和依赖包
[root@iZ285pj7jhrZ local]# yum -y install make gcc-c++ cmake openssl openssl-devel bison-devel ncurses ncurses-devel wget perl perl-devel
3.开始编译安装mysql
cmake --no-warn-unused-cli \-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DMYSQL_DATADIR=/usr/local/mysql/data \-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \-DEXTRA_CHARSETS=all \-DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_unicode_ci \-DENABLE_PROFILING=1\-DENABLED_LOCAL_INFILE=1\-DWITH_READLINE=1\-DWITH_SSL=system \-DWITH_MYISAM_STORAGE_ENGINE=1\-DWITH_INNOBASE_STORAGE_ENGINE=1\-DWITH_ARCHIVE_STORAGE_ENGINE=1\-DWITH_BLACKHOLE_STORAGE_ENGINE=1\-DWITH_MEMORY_STORAGE_ENGINE=1\-DMYSQL_USER=mysql \-DMYSQL_TCP_PORT=3306
[root@iZ2873rjubzZ mysql-5.6.21]# make && make install #等待较长时间
[root@iZ2873rjubzZ mysql-5.6.21]# make clean #安装完后 清理一下临时文件
4.配置mysql
[root@iZ2873rjubzZ local]# chown -R mysql:mysql /usr/local/mysql #修改mysql目录的所属用户权限
#初始化脚本
[root@iZ2873rjubzZ data]# cd mysql/data
[root@iZ2873rjubzZ data]# /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
#设置mysql服务开机自动启动
[root@iZ2873rjubzZ mysql]# cp support-files/mysql.server /etc/init.d/mysql
[root@iZ2873rjubzZ mysql]# chkconfig mysql on
[root@iZ2873rjubzZ mysql]# service mysql start
Starting MySQL. SUCCESS![root@iZ2873rjubzZ mysql]#
[root@iZ2873rjubzZ mysql]# vim /etc/profile #修改环境变量 使得可以使用mysql命令 PATH添加/usr/local/mysql/bin
[root@iZ2873rjubzZ mysql]# source/etc/profile #使得配置文件生效
[root@iZ2873rjubzZ mysql]# mysql-uroot #使用root(这时没有密码)登录
