centos 6.10源码安装mysql5.5.62实验
查看系统版本
[root@ABC ~]# cat /etc/redhat-release
CentOS release 6.10 (Final)
下载mysql5.5.62源码包，解压后安装
tar –zxf mysql-5.5.62.tar.gz -C /usr/local/src
根据提示安装必要的依赖库文件
yum install -y gcc gcc-c++ ncurses-devel git cmake
预编译规划
Mysql软件安装目录/usr/local/mysql；mysql数据目录为/usr/local/mysql/data;
Mysql错误日志文件保存目录为/var/log/mysql/error.log,创建相应目录和用户并赋权
groupadd mysql&&useradd –r –g mysql –s /sbin/false
mkdir –p /usr/local/mysql/data&&chown –R mysql:mysql /usr/local/mysql
mkdir /var/log/mysql&&chown –R mysql:mysql /var/log/mysql
进入解压包目录，使用cmake预编译
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data/ -DSYSCONFDIR=/etc -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1
编译安装
make –j 4&& make install –j 4
进入安装目录执行操作
cd /usr/local/mysql
拷贝mysql服务脚本文件到系统目录
cp support-files/mysql.server /ect/init.d/mysqld
设置mysqld服务为开机自启动
chkconfig - -level 3 mysqld on
chkconfig - -list mysqld
启动mysql服务
service mysqld start
启动报错，无法正常启动
安装完5.5.62的mysql后，必需要先执行mysql_install_db才能执行后续操作
[root@ABC mysql]#/usr/local/mysql/ scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
/usr/local/mysql/bin/mysqladmin -u root password 'new-password'
/usr/local/mysql/bin/mysqladmin -u root -h 主机名 password 'new-password'
Alternatively you can run:
/usr/local/mysql/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
启动mysql服务
[root@ABC mysql]# service mysqld start
Starting MySQL SUCCESS!
修改环境变量，将mysql命令添加到系统中
PATH=$PATH:/usr/local/mysql/bin
要想使命令永久生效，需要将该命令添加到$HOME/.bashrc_profile文件末尾即可，
使用source $HOME/.bashrc_profile 让命令生效
安全初始化mysql
[root@ABC ~]# mysql_secure_installation
登陆mysql
[root@ABC ~]# mysql –u root –p password
查看端口和状态
[root@ABC mysql]# netstat -ntulp

重启测试
[root@b mysql]# service mysqld restart
ERROR! MySQL server PID file could not be found!
无法启动，提示server PID无法找到关闭selinux防火墙并重启测试
[root@b mysql]# vim /etc/selinux/config
[root@b mysql]# reboot
[root@ABC ~]# service mysqld restart
Shutting down MySQL. SUCCESS!
Starting MySQL.. SUCCESS!
至此数据库安装成功。
