1.准备安装文件

# 下载安装包
wget -c -P /tmp http://mirrors.hust.edu.cn/apache/incubator/skywalking/5.0.0-GA/apache-skywalking-apm-incubating-5.0.0-GA.tar.gz

# 解压
mkdir /opt/skywalking;\
tar xf /tmp/apache-skywalking-apm-incubating-5.0.0-GA.tar.gz -C /opt/skywalking

# 拷贝到安装位置
cd /opt/skywalking;\
mv apache-skywalking-apm-incubating 5.0.0;\
ln -s /opt/skywalking/5.0.0 /opt/skywalking/current

# 新建用户
useradd -s /sbin/nologin skywalking;\
mkdir /home/skywalking/data

2.安装Collector

2.1更改配置文件

# 备份配置文件
mv /opt/skywalking/current/config/application.yml /opt/skywalking/current/config/application.yml_bak

# 创建配置文件
tee /opt/skywalking/current/config/application.yml << 'EOF'

2.2创建服务

tee /etc/systemd/system/skywalking-collector.service << 'EOF'
[Unit]
Description=Skywalking Collector
After=network.target

[Service]
Environment="JAVA_HOME=/usr/java/default" "COLLECTOR_HOME=/opt/skywalking/current"
Type=forking
User=skywalking
Group=skywalking
LimitNOFILE=65535
ExecStart=/opt/skywalking/current/bin/collectorService.sh
Restart=on-failure
WorkingDirectory=/opt/skywalking/current

[Install]
WantedBy=multi-user.target
EOF

2.3启动脚本删除注释行

因原有脚本行首有注释导致systemd启动报错

sed -i -c -e '/^#/d' /opt/skywalking/current/bin/collectorService.sh;\
sed '1 i#!/usr/bin/env sh' -i /opt/skywalking/current/bin/collectorService.sh

2.4启动服务

chown -R skywalking. /home/skywalking /opt/skywalking;\
systemctl daemon-reload;\
systemctl enable skywalking-collector;\
systemctl start skywalking-collector;\
systemctl status skywalking-collector

2.5配置防火墙

firewall-cmd --add-port=10800/tcp --permanent;\
firewall-cmd --add-port=11800/tcp --permanent;\
firewall-cmd --add-port=12800/tcp --permanent;\
firewall-cmd --reload

3.安装UI

3.1更改配置

# 备份
mv /opt/skywalking/current/webapp/webapp.yml /opt/skywalking/current/webapp/webapp.yml_bak

# 创建配置文件
tee /opt/skywalking/current/webapp/webapp.yml << 'EOF'
server:

  ribbon:
    ReadTimeout: 10000
    listOfServers: 192.168.1.41:10800,192.168.1.42:10800,192.168.1.43:10800

security:
  user:
    admin:
      password: Password_2018
EOF

3.2启动脚本删除注释行

因原有脚本行首有注释导致systemd启动报错

sed -i -c -e '/^#/d' /opt/skywalking/current/bin/webappService.sh;\
sed '1 i#!/usr/bin/env sh' -i /opt/skywalking/current/bin/webappService.sh

3.3创建服务

tee /etc/systemd/system/skywalking-ui.service << 'EOF'
[Unit]

3.5启动服务

chown -R skywalking. /home/skywalking /opt/skywalking;\
systemctl daemon-reload;\
systemctl enable skywalking-ui;\
systemctl start skywalking-ui;\
systemctl status skywalking-ui

3.6配置防火墙
