如何在本地运行vitess范例

社区秘书 2019-11-18 13:57:50 686

最近在研究 mysql水平扩展,有朋友推荐 vitess . 自己在 oracle linux 7.6 上搭了个环境测试了下。 计划是使用 sysbench 连接 vitess 然后 将 mysql 发布在 3台物理机上,看看 是否能正确运行, 然后看看性能跟单机对比如何。 sysbench 符合 tpcc 规范, 是标准的 oltp 类似应用程序。 用来测试性能。 可以看外网的可以看看 。https://github.com/gaogaolulu/how_to_run_vitess_locally 首先准备 oracle linux , 下载安装 7.6 关闭 selinux 和 firewall 。 关闭 ipv6

/*** there are several options(onl linux here) we can choose for running vitess: Redhat, Oracle Linux, CentOS, Debian, Ubuntu. for me, the company which I am woring with only uses Oracle Linux, so I use it ot setup Vitess. please use root to finish following steps.
/ Step 1. / installing Oracle Linux 7.6 from scatch , please refer to official doc. / Step 2. / disable IPV6 : I tried a lot of time to execute the first script 101_initial_cluster.sh ,and foud vitess listens both IPV4 and IPV6 port , and Vitess other part only access IPV4 port. ash-4.2$ netstat -lnt Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 127.0.0.1:47814 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:199 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:17100 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:17101 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:17102 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN tcp 0 0 10.87.200.72:28883 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:21811 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:21812 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:21813 0.0.0.0:* LISTEN tcp 0 0 192.168.42.1:53 0.0.0.0:* LISTEN tcp 0 0 192.168.122.1:53 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN tcp 0 0 10.87.200.72:38881 0.0.0.0:* LISTEN tcp 0 0 10.87.200.72:38882 0.0.0.0:* LISTEN tcp 0 0 10.87.200.72:38883 0.0.0.0:* LISTEN tcp6 0 0 :::16101 :::* LISTEN tcp6 0 0 :::16102 :::* LISTEN tcp6 0 0 :::2224 :::* LISTEN tcp6 0 0 :::22 :::* LISTEN tcp6 0 0 :::15000 :::* LISTEN tcp6 0 0 :::15100 :::* LISTEN tcp6 0 0 :::15101 :::* LISTEN tcp6 0 0 :::15102 :::* LISTEN tcp6 0 0 :::15999 :::* LISTEN tcp6 0 0 :::16100 :::* LISTEN bash-4.2$ / vi /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.wlp0s26f7u1.disable_ipv6 = 1 net.ipv6.conf.enp0s25.disable_ipv6 = 1 step 3. / modify grub.cfg , add: ipv6.disable=1 to startup parameter / cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bkk vi /etc/default/grub GRUB_CMDLINE_LINUX="rd.lvm.lv=ol/root rd.lvm.lv=ol/swap rhgb quiet ipv6.disable=1" step 4. / generate cfg file / grub2-mkconfig -o /boot/grub2/grub.cfg step 5. / disable selinux , fire wall / systemctl disable firewalld systemctl stop firewalld vi /etc/selinux/config SELINUX=disabled step 6. / add user: mysql , due to PAM , we must use login system with GUI, and add user manually. ****/ login system with GUI , and add user mysql step 7. reboot
