percona-server-5.7.18-14安装

说明

percona-server-5.7 的安装对硬件配置的要求较高，至少需要4G内存或者2G物理内存+2Gswap。

编译安装过程中注意所在分区的空间大小，编译安装需要使用到大量的临时空间。

环境配置

[root@ ~]# groupadd mysql
[root@ ~]# useradd -g mysql -M mysql

使用 yum 命令安装以下软件，已安装的可以略去：

[root@ ~]# yum install -y gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel*  readline-devel 

percona-server 从 5.7 开始要求使用高于2.8版本的 cmake 进行编译

[root@ ~]# yum update -y cmake

TCMalloc(Thread-Caching Malloc)与标准glibc库的malloc实现一样的功能， 与标准的glibc库的malloc相比，TCMalloc在内存的分配效率和速度要高，可以在高并发的情况下很好的控制内存的使用，提高服务器的性能，降低负载。TCMalloc的安装这里省略

安装percona-server-5.7.18-14

编译安装

[root@ ~]# CPUcount=`cat /proc/cpuinfo  | grep processor | wc -l`
[root@ ~]# cd /dist/dist
[root@ dist]# wget https://www.percona.com/downloads/Percona-Server-LATEST/Percona-Server-5.7.18-14/source/tarball/percona-server-5.7.18-14.tar.gz
[root@ dist]# cd /dist/src
[root@ src]# tar xf /dist/dist/percona-server-5.7.18-14.tar.gz

percona-server 从 5.7 开始需要使用 boost_1.59.x

[root@ src]# cd percona-server-5.7.18-14/
[root@ percona-server-5.7.18-14]#wget https://sourceforge.mirrorservice.org/b/bo/boost/boost/1.59.0/boost_1_59_0.tar.gz

5.7版本，不再支持： innodb_additional_mem_pool_size、table_cache 两个参数

[root@ percona-server-5.7.18-14]# make -j $CPUcount
[root@ percona-server-5.7.18-14]# make install

生成初始数据库

5.7版本使用 bin/mysqld --initialize 进行初始化

[root@ mysql]#/usr/local/mysql/bin/mysqld --initialize --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/var/ --user=mysql

MySQL数据库初始化完成以后，会产生一个 root@localhost 用户，从MySQL 5.7开始，root用户的密码不再是空，而是随机产生一个密码。初始化过程中将随机生成root密码：

[Note] A temporary password is generated for root@localhost: KJ1foE6BFX;3

这个密码在第一次登录时会被要求重制。

启动数据库

[root@ ~]# /usr/local/mysql/bin/mysqld_safe  & 

数据库启动时，可能会启动失败并提示没有错误日志文件，手动创建并授权即可

2017-06-30T06:24:07.752061Z mysqld_safe Logging to '/data/database/mysql//localhost.err'.
2017-06-30T06:24:07.761038Z mysqld_safe error: log-error set to '/data/database/mysql//localhost.err', however file don't exists. Create writable for user 'mysql'.
