Gitlab-多实例搭建

操作系统：CentOS

所有服务如下:

节点A：OpenResty、grafana-server
节点B：PGSQL、Redis
节点C：Gitlab_1
节点D：Gitlab_2
节点E：Gitlab_3
..............
节点N：Gitlab_n

节点A

OpenResty

装置参考https://openresty.org/cn/inst…

# 装置相干依赖
yum install pcre-devel openssl-devel gcc curl

# 下载源码包
wget https://openresty.org/download/openresty-1.19.9.1.tar.gz

# 装置源码包，VERSION=1.19.9.1
tar -xzvf openresty-VERSION.tar.gz
cd openresty-VERSION/
./configure --prefix=/opt/openresty \
            --with-luajit \
            --without-http_redis2_module \
            --with-http_iconv_module \
            --with-http_postgres_module
make
sudo make install

# 启动openresty
# 重启服务 sudo /opt/openresty/bin/openresty -s reload
# 进行服务 sudo /opt/openresty/bin/openresty -s stop
sudo /opt/openresty/bin/openresty

grafana-server

装置参考https://grafana.com/docs/graf…

# 装置，这里的<rpm package url>和<local rpm package>
# 替换成所需版本的包
sudo yum install initscripts urw-fonts wget
wget <rpm package url>
sudo rpm -Uvh <local rpm package>

# 启动
sudo systemctl daemon-reload
sudo systemctl start grafana-server
sudo systemctl status grafana-server
sudo systemctl enable grafana-server

节点B

搭建redis

参考https://hub.docker.com/_/redis

# 拉取最新的redis镜像
docker pull redis

# 启动redis服务
docker run \
    -v <your_conf>:/usr/local/etc/redis \
    --name <your_redis> redis \
    redis-server \
    /usr/local/etc/redis/redis.conf

搭建PGSQL

参考https://hub.docker.com/_/post…

# 拉取最新的PGSQL镜像
docker pull postgres

# 启动redis服务
docker run \
    --name postgresql -p 15432:5432 \
    -e POSTGRES_USER=<your_pg_user> \
    -e POSTGRES_DB=<your_pg_db> \
    -e POSTGRES_PASSWORD=<your_pg_passwd> \
    -d postgres

节点C~N

搭建gitlab

参考https://docs.gitlab.com/ee/up…

# 装置依赖
yum -y install policycoreutils openssh-server openssh-clients postfix

# 开启postfix反对gitlab发信性能
# postfix启动过程会报错：fatal: parameter inet_interfaces: no local interface found for ::1 
# 须要批改/etc/postfix/main.cf里的inet_interfaces = localhost改为inet_interfaces = all 保留配置后重启postfix即可
systemctl enable postfix && systemctl start postfix 

# 装置gitlab
# 手动下载安装包
# 国内镜像源网址 https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/
rpm -ivh <package_name>
