一、配置yum源
# 注意,阿里云和腾讯云的yum源二选一即可
mv /etc/yum.repos.d/CentOS-Base.repo{,.orig} #阿里云 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo #腾讯云 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo #替换完后,更新缓存 yum clean all yum makecache
二、安装jemalloc
# 运行GreatSQL可能需要依赖jemalloc库,因此请先先安装上 cd /opt/ yum -y install jemalloc jemalloc-devel
#也可以把自行安装的lib库so文件路径加到系统配置文件中,例如:
[root@mgr131 ~]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
[root@mgr131 ~]#
而后执行下面的操作加载libjemalloc库,并确认是否已存在
[root@mgr131 ~]# ldconfig [root@mgr131 ~]# ldconfig -p | grep libjemalloc libjemalloc.so.1 (libc6,x86-64) => /lib64/libjemalloc.so.1 libjemalloc.so (libc6,x86-64) => /lib64/libjemalloc.so [root@mgr131 ~]#
三、修改/etc/hosts
# 请修改/etc/hosts cat <<EOF >>/etc/hosts 192.168.29.131 mgr131 192.168.29.132 mgr132 192.168.29.133 mgr133 EOF
四、修改主机名
# 修改主机名 hostnamectl set-hostname mgr131 hostnamectl set-hostname mgr132 hostnamectl set-hostname mgr133
五、安装系统依赖包
# 这里是Centos7最小化安装,所以将常用的都安装一下
yum -y install make gcc-c++ cmake bison-devel ncurses-devel readline-devel >/dev/null 2>&1 yum -y install libaio-devel libaio wget lrzsz vim libnuma* bzip2 xz tree >/dev/null 2>&1 yum -y install perl grep glibc libgcc libstdc++ numactl cyrus-sasl-lib coreutils-libs >/dev/null 2>&1 yum -y install epel-release >/dev/null 2>&1 yum -y install perl-DBD-MySQL >/dev/null 2>&1 yum -y install perl-Config-Tiny >/dev/null 2>&1 yum -y install perl-Digest-MD5 >/dev/null 2>&1 yum -y install perl-Log-Dispatch perl-Time-HiRes >/dev/null 2>&1 yum -y install perl-Parallel-ForkManager ntp perl cpan >/dev/null 2>&1 yum -y install perl perl-devel perl-Time-HiRes perl-DBD-MySQL >/dev/null 2>&1 yum -y install zlib-devel bzip2-devel openssl-devel tk-devel gcc make >/dev/null 2>&1 yum -y install gcc automake autoconf bzr bison libtool ncurses5-devel >/dev/null 2>&1
六、关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config setenforce 0 2>/dev/null
七、修改系统限制参数
cat <<EOF >> /etc/security/limits.conf # ###########################custom######## # * soft nproc 20480 * hard nproc 65535 * hard nofile 1000000 * soft nofile 1000000 ########################################## EOF
八、创建用户
groupadd mysql >/dev/null 2>&1 useradd -g mysql -s /sbin/nologin -d /usr/local/mysql -MN mysql >/dev/null 2>&1
九、下载安装包
cd /opt/ wget https://product.greatdb.com/8.0.25-15/GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64.tar.xz
十、拷贝软件包
# 我这里是三台测试环境,为之后的mgr准备 [root@mgr131 opt]# for i in 192.168.29.132 192.168.29.133; do scp GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64.tar.xz root@$i:/opt ; done GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64.tar.xz 100% 506MB 58.8MB/s 00:08 GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64.tar.xz 100% 506MB 107.4MB/s 00:04 [root@mgr131 opt]#
十一、创建目录并修改权限
mkdir -p /data/GreatSQL/mgr/data/{data,logs,tmp} chown -R mysql.mysql /data/GreatSQL
十二、初始化数据库
# my.cnf配置文件具体内容详见下文附录部分 # 执行下面的命令进行MySQL实例初始化,会自动创建InnoDB系统表空间、redo log、undo log的文件: cd /opt/ tar -xJf GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64.tar.xz -C /usr/local cd /usr/local ln -s GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64 mysql chown -R mysql:mysql /usr/local/mysql chown -R mysql.mysql /data/GreatSQL chown -R mysql.mysql GreatSQL-8.0.25-15-Linux-glibc2.17-x86_64
初始化
#/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/data/GreatSQL/mgr/data/data --initialize & /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/data/GreatSQL/mgr/data/data --initialize-insecure &
十三、配置mysql命令环境
echo "export PATH=$PATH:/usr/local/mysql/bin" >>/etc/profile source /etc/profile
十四、启动、停止、重启GreatSQL
cp /usr/local/mysql/support-files/mysql.server /usr/local/mysql/bin/ /usr/local/mysql/bin/mysql.server start #/usr/local/mysql/bin/mysql.server stop #/usr/local/mysql/bin/mysql.server restart
十五、登录测试
[root@mgr131 local]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 9 Server version: 8.0.25-15 GreatSQL, Release 15, Revision c7feae175e0 Copyright (c) 2021-2021 GreatDB Software Co., Ltd Copyright (c) 2009-2021 Percona LLC and/or its affiliates Copyright (c) 2000, 2021, Oracle and/or its affiliates.
