如何在centos7系统下编译安装mysql5.7?
一、安装约定
mysql安装路径: /usr/local/mysql
mysql数据库路径: /data/mysql
my配置文件路径: /usr/local/mysql/my.cnf
二、卸载mariadb
# rpm -qa | grep mariadb # rpm -e --nodeps mariadb-libs-5.5.37-1.el7_0.x86_64 包名是上一条查询得知
三、创建用户组、用户
添加mysql组 groupadd mysql
添加用户 useradd -g mysql mysql -s /bin/false
#下载源码包
在官网如下地址下载最新版
http://dev.mysql.com/downloads/mysql/5.7.html#downloads
http://download.savannah.gnu.org/releases/libunwind/
https://github.com/gperftools/gperftools/releases
# cd /usr/local/src/ # wget http://download.savannah.gnu.org/releases/libunwind/libunwind-1.1.tar.gz # wget http://gperftools.googlecode.com/files/gperftools-2.5.tar.gz # wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.x.tar.gz
libunwind安装
# tar zxvf libunwind-1.1.tar.gz # cd libunwind-1.1 # ./configure # make # make install
gperftools安装
# cd .. # tar zxvf gperftools-2.1.tar.gz # cd gperftools-2.1 # ./configure # make # make install # echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf # ldconfig
mysql安装
# cd .. # tar zxvf mysql-5.7.x.tar.gz # cd mysql-5.7.x
编译前可用如下命令查看编译参数说明
# cmake . -LH | more
如果中间过程有报错,请删除CMakeCache.txt,在重新编译
rm -rf CMakeCache.txt
mysq编译安装
# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/data/mysql \ -DSYSCONFDIR=/etc \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DMYSQL_UNIX_ADDR=/dev/shm/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DMYSQL_USER=mysql \ -DWITH_DEBUG=0 \ -DDOWNLOAD_BOOST=1 \ -DWITH_BOOST=/usr/local/boost # make # make install ``` 更改权限 ``` # chmod 755 /var/lib/mysql # cd /usr/local/mysql # chown -R mysql:mysql .
初始化mysql
/usr/local/mysql/bin/mysqld --initialize --basedir=/usr/local/mysql --datadir=/data/mysql --user=mysql --explicit_defaults_for_timestamp=1
创建mysql配置文件
# cp support-files/my-default.cnf /usr/local/mysql/my.cnf
