卸载源码安装mysql_CentOS7下源码安装MySQL5.7.6+

卸载CentOS7默认携带的mariadb包

# 检查mariadb安装包

[root@wing ~]# rpm -qa | grep -i mysql

[root@wing ~]# rpm -qa | grep -i mariadb

mariadb-libs-5.5.50-1.el7_2.x86_64

# 卸载mariadb安装包

[root@wing ~]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64

error: Failed dependencies:

libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64

libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64

[root@wing ~]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64 postfix-2:2.10.1-6.el7.x86_64

安装编译软件

yum install -y cmake make gcc gcc-c++

创建MySQL安装目录

# 如MySQL安装目录为：/usr/local/mysql

mkdir -p /usr/local/mysql

解压MySQL源码包

tar -zxvf mysql-5.7.16.tar.gz

创建mysql用户和用户组

# 创建用户组

groupadd mysql

# 创建mysql用户，所属组为mysql

useradd -s /bin/bash -m -g mysql mysql

安装MySQL相关依赖包

yum install -y ncurses-devel openssl-devel bison-devel libaio libaio-devel

boost库安装

# 该步骤可以省略，在cmake阶段添加参数-DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost即可

# boost库安装

wget http://sourceforge.net/projec...

tar -zxvf boost_1_59_0.tar.gz -C /usr/local

mv /usr/local/boost_1_59_0 /usr/local/boost

cd /usr/local/boost

./bootstrap.sh

./b2 stage threading=multi link=shared

./b2 install threading=multi link=shared

创建MySQL相关目录

目录 含义 配置参数

bin_log 二进制日志目录 log_bin_basename

log_bin_index

mydata 数据文件目录 datadir

innodb_log InnoDB重做日志目录 innodb_log_group_home_dir

innodb_ts InnoDB共享表空间目录 innodb_data_home_dir

log 日志文件目录(error log+general log+slow log) log_error

general_log_file

slow_query_log_file

relay_log InnoDB中继日志目录 relay_log_basename

relay_log_index

tmpdir 临时文件目录 tmpdir

undo_log InnoDB回滚日志目录 innodb_undo_directory

mkdir -p /data/mysql/mysql3306/bin_log

mkdir -p /data/mysql/mysql3306/db_file

mkdir -p /data/mysql/mysql3306/innodb_log

mkdir -p /data/mysql/mysql3306/innodb_ts

mkdir -p /data/mysql/mysql3306/log

mkdir -p /data/mysql/mysql3306/relay_log

mkdir -p /data/mysql/mysql3306/tmpdir

mkdir -p /data/mysql/mysql3306/undo_log

修改步骤9创建的目录的所属用户与所属组为mysql:mysql

chown -R mysql:mysql /data/mysql/mysql3306

将MySQL配置文件my.cnf放置到/etc目录下
