服务器配置及优化
变更内容请参考实战教程第二章2.4，如何初始化服务器环境(https://open.oceanbase.com/blog/8600144)，内容比较详细。
下载软件
从https://www.oceanbase.com/softwareCenter/community下载3个软件，分别是obproxy-3.2.0-1.el7.x86_64.rpm、oceanbase-ce-3.1.1-4.el7.x86_64.rpm、oceanbase-ce-libs-3.1.1-4.el7.x86_64.rpm。
安装软件
使用root用户执行安装：
[root ~] # rpm -ivh oceanbase-ce-3.1.1-4.el7.x86_64.rpm [root ~] # rpm -ivh oceanbase-ce-libs-3.1.1-4.el7.x86_64.rpm [root ~] # rpm -ivh obproxy-3.2.0-1.el7.x86_64.rpm
查看安装后的信息：
[root ~] # rpm -ql oceanbase-ce /home/admin/oceanbase/bin /home/admin/oceanbase/bin/import_time_zone_info.py /home/admin/oceanbase/bin/observer /home/admin/oceanbase/etc /home/admin/oceanbase/etc/timezone_V1.log [root ~] # rpm -ql oceanbase-ce-libs /home/admin/oceanbase/lib /home/admin/oceanbase/lib/libaio.so /home/admin/oceanbase/lib/libaio.so.1 /home/admin/oceanbase/lib/libaio.so.1.0.1 /home/admin/oceanbase/lib/libmariadb.so /home/admin/oceanbase/lib/libmariadb.so.3 [root ~] # rpm -ql obproxy /home/admin/obproxy-3.2.0/bin /home/admin/obproxy-3.2.0/bin/obproxy /home/admin/obproxy-3.2.0/bin/obproxyd.sh
创建admin用户
OceanBase建议使用admin进行维护，创建admin用户。
[root ~] # useradd admin [root ~] # passwd admin # 修改admin用户密码
给予admin用户sudo root权限：
[root ~] # cd /etc/sudoers.d/ # 创建admin(文件可随意),并写入如下内容： [root ~] # more admin %admin ALL=(ALL) NOPASSWD: ALL
创建运行目录
[root ~] # mkdir /data
[root ~] # chown admin:admin /data
## 切换到admin用户下执行.
[admin ~]$ mkdir -p /data/{observer01,observer02,observer03,obproxy}
[admin ~]$ mkdir -p /data/observer{01,02,03}/store/{sort_dir,sstable,clog,ilog,slog}
配置lib信息
[admin ~]$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/admin/oceanbase/lib/
# 也可以将以上内容写入到admin用户的.bash_profile中，然后执行source ~/.bash_profile生效。
启动OB进程
[admin ~]$ cd /data/observer01/ && /home/admin/oceanbase/bin/observer -r "192.168.211.54:2882:2881;192.168.211.54:3882:3881;192.168.211.54:4882:4881" -o __min_full_resource_pool_memory=268435456,memory_limit=8G,system_memory=4G,stack_size=512K,cpu_count=16,cache_wash_threshold=1G,workers_per_cpu_quota=10,schema_history_expire_time=1d,net_thread_count=4,sys_bkgd_migration_retry_num=3,minor_freeze_times=10,enable_separate_sys_clog=0,enable_merge_by_turn=False,datafile_size=50G,enable_syslog_recycle=True,max_syslog_file_count=10 -z zone1 -p 2881 -P 2882 -c 1 -d /data/observer01/store -i eth0 -l INFO
