1. Gerrit镜像机器配置
安装与主Gerrit相同版本的Gerrit，认证方式跟主Gerrit保持一致。
gerrit.config增加如下配置
| [cache "accounts"]
maxAge = 3 min
[cache "groups"]
maxAge = 3 min
[cache "sshkeys"]
maxAge = 3 min
[cache "groups_byuuid"]
maxAge = 3 min
[cache "projects"]
maxAge = 3 min
|
| #!/bin/bash
ipaddr=192.168.IP
echo "***"
echo "Can't push commit to this server!"
echo "please run the commands below and push again:"
echo " git config --global --add url.\"\".pushinsteadof http://${ipaddr}:8080"
echo " git config --global --add url.\"ssh://${uploader_name}@gerritURL:29418\".pushinsteadof ssh://${uploader_name}@${ipaddr}:29418"
echo "***"
exit 1
|
2. Gerrit主机配置
配置gerrit主机到所有镜像服务器的ssh信任关系，主机和镜像机器均使用gerrit的安装账号。
| ssh-copy-id linux@replication1
ssh-copy-id linux@replication2
ssh-copy-id linux@replication3
ssh-copy-id linux@replication4
|
| [gerrit]
autoReload = true
replicateOnStartup = true
[remote "mirror_xian"]
url = linux@replication1:/home/linux/review/git/${name}.git
url = linux@replication2:/home/linux/review/git/${name}.git
url = linux@replication3:/home/linux/review/git/${name}.git
url = linux@replication4:/home/linux/review/git/${name}.git
push = +refs/heads/*:refs/heads/*
push = +refs/tags/*:refs/tags/*
push = +refs/users/*:refs/users/*
push = +refs/meta/external-ids:refs/meta/external-ids
push = +refs/starred-changes/*:refs/starred-changes/*
push = +refs/sequences/accounts:refs/sequences/accounts
push = +refs/groups/*:refs/groups/*
push = +refs/meta/group-names:refs/meta/group-names
push = +refs/sequences/groups:refs/sequences/groups
push = +refs/meta/config:refs/meta/config
mirror = true
threads = 3
|
配置完成最好重启下Gerrit。
3. 负载均衡主机
需要安装ipvsadm工具， apt install ipvsadm
创建/etc/start_lvs.sh，内容如下，保存后增加执行权限并手动运行一次。
| #!/bin/bash
sleep 15
echo 1 > /proc/sys/net/ipv4/ip_forward
VIP=192.168.IP
PORT=29418
ip addr add $VIP/32 broadcast $VIP dev enp3s0 label enp3s0:0
#ip route add $VIP dev enp3s0:0
ipvsadm -A -t $VIP:$PORT -s wrr
ipvsadm -a -t $VIP:$PORT -r replication1:$PORT -g -w 2
ipvsadm -a -t $VIP:$PORT -r replication2:$PORT -g -w 2
ipvsadm -a -t $VIP:$PORT -r replication3:$PORT -g -w 2
ipvsadm -a -t $VIP:$PORT -r replication4:$PORT -g -w 1
exit 0
|
然后配置/etc/rc.local为以下内容实现开机启动。
| #!/bin/bash
/etc/start_lvs.sh &
exit 0
|
4. Gerrit镜像机器配置
/etc/rc.local配置为以下内容。
| #!/bin/bash
echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
ip addr add 192.168.IP broadcast 192.168.IP dev lo label lo:0
ip route add 192.168.IP dev lo:0
exit 0
|
保存后增加执行权限并手动运行一次。
| chmod +x /etc/rc.local
/etc/rc.local
|
5. 研发本地配置
因为使用的是ssh协议，所以所有研发需要在本地的~/.ssh/config文件增加如下配置，没有就新建这个文件，当然如果使用http协议的话则没有这个问题。
| StrictHostKeyChecking no
UserKnownHostsFile /dev/null
|
还要使用如下命令配置pushinsteadof，因为是读写分离，拉代码都是从镜像服务器上拉取，提交的时候则需要提交到主gerrit服务器。
| git config --global --add url."ssh://账号@gerritURL:29418".pushinsteadof ssh://账号@192.168.IP:29418
