2.二进制安装(自定义安装目录)
1)上传包
[root@db03 ~]# rz
2)安装依赖
[root@db03 ~]# yum install -y ncurses-devel libaio-devel cmake glibc autoconf gcc-c++
3)解压
[root@db03 ~]# tar xf mysql-5.6.42-linux-glibc2.12-x86_64.tar.gz
4)创建自定义目录
[root@db03 ~]# mkdir /service
5)移动并改名
[root@db03 ~]# mv mysql-5.6.42-linux-glibc2.12-x86_64 /service/mysql-5.6.42
6)做软连接
[root@db03 ~]# ln -s /service/mysql-5.6.42 /service/mysql
7)创建用户
[root@db03 ~]# useradd mysql -s /sbin/nologin -M
8)拷贝启动文件和配置文件
[root@db03 ~]# cd /service/mysql/support-files/
[root@db03 /service/mysql/support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite '/etc/my.cnf'? y
[root@db03 /service/mysql/support-files]# cp mysql.server /etc/init.d/mysqld
9)初始化
[root@db03 ~]# cd /service/mysql/scripts/
[root@db03 /service/mysql/scripts]# ./mysql_install_db --user=mysql --basedir=/service/mysql --datadir=/service/mysql/data
10)配置system管理启动MySQL
[root@db03 ~]# vim /usr/lib/systemd/system/mysqld.service
[Unit]
Description=MySQL Server
Documentation=man:mysqld(8)
Documentation=https://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=mysql
Group=mysql
ExecStart=/service/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf
LimitNOFILE = 5000
[root@db03 ~]# systemctl daemon-reload
11)启动数据库
#1.使用system启动
[root@db03 ~]# systemctl start mysqld
#查看进程启动失败,没有任何报错
#2.使用mysqld启动脚本启动
[root@db03 ~]# /etc/init.d/mysqld start
/etc/init.d/mysqld: line 244: my_print_defaults: command not found
/etc/init.d/mysqld: line 264: cd: /usr/local/mysql: No such file or directory
Starting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe)
#原因:二进制的包是源码包已经生成编译安装完成的,在cmake阶段已经指定了所有的目录都是/usr/local/mysql,所以启动时所有程序都去找/usr/local/mysql目录,没有该目录,所以启动失败
#3.解决启动问题
1)方法一:做软连接
[root@db03 ~]# ln -s /service/mysql /usr/local/mysql
2)方法二:修改启动文件
[root@db03 ~]# vim /etc/init.d/mysqld
basedir=/service/mysql
datadir=/service/mysql/data
#4.再次测试启动
[root@db03 ~]# /etc/init.d/mysqld start
Starting MySQL. SUCCESS!
#或者
[root@db03 ~]# systemctl start mysqld
12)设置环境变量
[root@db02 ~]# vim /etc/profile.d/mysql.sh
export PATH=/service/mysql/bin:$PATH
[root@db02 ~]# source /etc/profile
